  1. 0:00If you've been unable to get on with
  2. 0:01hearing aids, your team may have talked
  3. 0:03to you about the option of bone
  4. 0:05conduction technology. It's a great time
  5. 0:07for patients as there are now more
  6. 0:08choices than ever before. But that also
  7. 0:10means a challenge. How do you figure out
  8. 0:12which is best for you? I'm a hearing
  9. 0:14implant surgeon at University College
  10. 0:16London. And in 2023, I made a video for
  11. 0:19my own patients comparing each bone
  12. 0:21conduction device to help them navigate
  13. 0:23this choice. It ended up being shared
  14. 0:25and used by colleagues in a number of
  15. 0:27different cities. But technology also
  16. 0:29moves fast and it's now 2025. The
  17. 0:31landscape has changed and it's time for
  18. 0:33an update. So, this is your complete
  19. 0:36unbiased and unsponsored guide to bone
  20. 0:38conduction hearing devices. We're going
  21. 0:40to cover the fundamentals of bone
  22. 0:42conduction hearing, a full review of all
  23. 0:44the main options available today, a
  24. 0:46head-to-head comparison of how they
  25. 0:48differ in terms of surgery, visibility,
  26. 0:51power, and MRI compatibility, and
  27. 0:53finally, the key further questions that
  28. 0:56you might choose to ask to help you
  29. 0:57decide. I've included chapters in the
  30. 0:59timeline so you can easily find what
  31. 1:01you're looking for. And if spoken
  32. 1:02English isn't your first language, then
  33. 1:04there are also different language
  34. 1:06captions available if you're watching on
  35. 1:08YouTube. Right, let's get started.
  36. 1:10Hearing is precious and yet the impact
  37. 1:12of hearing loss and deafness is often so
  38. 1:14underestimated because it is so
  39. 1:16invisible. It's so easy to be mistaken
  40. 1:18for being rude when you've not actually
  41. 1:20heard something. And people are maybe
  42. 1:22just less likely to adjust for your
  43. 1:23needs in a way that's so different to if
  44. 1:25you, for example, had two broken legs
  45. 1:28where people would be clearly showing
  46. 1:29you empathy and holding doors open for
  47. 1:31you. But we know that unmanaged hearing
  48. 1:33loss has direct impact on social
  49. 1:36isolation, on marriage and relationship
  50. 1:38strain, employment prospects and overall
  51. 1:40daily listening effort and the mental
  52. 1:42fatigue that that brings. Even more
  53. 1:44underestimated even by us ENT surgeons
  54. 1:47than the previous generation is the
  55. 1:49impact of even having hearing loss in
  56. 1:51just one ear. Even if the other ear is
  57. 1:52fine in a quiet room, it's going to be
  58. 1:54far less noticeable to the doctor
  59. 1:55looking after you. But single-sided
  60. 1:57hearing loss will particularly make
  61. 1:59difficult noisy environments. And to
  62. 2:01localize where a sound is coming from,
  63. 2:03it also leads to what we call a head
  64. 2:05shadow effect where you miss one half of
  65. 2:07your environment. Think about the car
  66. 2:08coming down the street or someone
  67. 2:10calling you from that side. And of
  68. 2:12course that high listening effort again
  69. 2:14and the tiredness that comes with it. So
  70. 2:15what can we do about all of this in
  71. 2:172025? Well, to understand the solutions,
  72. 2:20it's first worth understanding how
  73. 2:22exactly hearing works. Each of your ears
  74. 2:24delivers sound to your brain via, if you
  75. 2:26like, a conduction system connected to a
  76. 2:29microphonic system. The conduction
  77. 2:31system is made up of your outer ear,
  78. 2:33including your ear canal, and also your
  79. 2:35eard drum and three bones behind the
  80. 2:37eardrum that carry sound vibrations and
  81. 2:39concentrate them onto a small window
  82. 2:41into the inner ear, the microphonic part
  83. 2:43of the ear, the coccleia as we call it,
  84. 2:45which converts mechanical vibrations
  85. 2:47into electrical signals that are then
  86. 2:49delivered to the brain. Now, people can
  87. 2:51lose hearing as a result of problems
  88. 2:52anywhere along that pathway. But if we
  89. 2:54focus in on that conduction system,
  90. 2:56problems can include scarring up of the
  91. 2:58ear canal, damage to the eardrum itself,
  92. 3:00or damage to the hearing bones behind.
  93. 3:02And some people are even born with some
  94. 3:04of those components missing. Now, in
  95. 3:06these cases, a surgeon will first ask
  96. 3:08the question whether some of this can be
  97. 3:10reconstructed and recreated with
  98. 3:12microscopic surgery. So, you might hear
  99. 3:14the terms canal plasty or tempanoplasty
  100. 3:16or stapecttomy used for this type of
  101. 3:19surgery. And these should generally be
  102. 3:20considered first where possible and this
  103. 3:23is something your surgeon will usually
  104. 3:24discuss with you. Now in some cases
  105. 3:26though these procedures are either not
  106. 3:28technically possible or deemed too risky
  107. 3:31or have already even been tried and in
  108. 3:33this case the next step is to then ask
  109. 3:36is a conventional hearing aid an option.
  110. 3:38However, there are a number of reasons
  111. 3:39why this might also not be suitable.
  112. 3:42Whether that be because of the ear size
  113. 3:44and shape causing recurrent infections
  114. 3:46or if the hearing levels are too low for
  115. 3:48even the strongest hearing aid. Now for
  116. 3:50those that have reached this scenario,
  117. 3:52we can potentially use the magic of bone
  118. 3:54conduction to provide good hearing.
  119. 3:56Again, now to establish whether your
  120. 3:58hearing might be suitable for a bone
  121. 4:00conduction device, we look at your
  122. 4:01aiogram. And rather than looking at your
  123. 4:04overall hearing levels, usually the
  124. 4:05lower line or what we call your air
  125. 4:07conduction thresholds, we instead pay
  126. 4:09particular attention to where your bone
  127. 4:11conduction thresholds are. In many
  128. 4:13cases, people with outer and middle ear
  129. 4:15problems can have quite poor hearing,
  130. 4:16but their bone conduction thresholds are
  131. 4:18actually still quite good. And this is
  132. 4:20then a route we can utilize in a way
  133. 4:22that we can't with a regular hearing
  134. 4:24aid. With bone conduction, instead of
  135. 4:26sending sound vibrations through a
  136. 4:28poorly functioning ear canal and middle
  137. 4:30ear, we bypass that part entirely. The
  138. 4:32device picks up sound and vibrates it
  139. 4:34through the skull directly to the inner
  140. 4:37ear. The vibrations reaching the inner
  141. 4:39ear are then converted to electrical
  142. 4:40signal to the brain as normal. In fact,
  143. 4:42a fascinating fact about this is that
  144. 4:44the composer Beethoven, as he became
  145. 4:47deaf, found that he could bite on his
  146. 4:49conductor's batn and press the other end
  147. 4:51to his piano to hear the music through
  148. 4:53the bones in his jaw. Now, we can also
  149. 4:55use this route for people that have no
  150. 4:58even microphonic hearing on one side.
  151. 5:00You might hear this term single-sided
  152. 5:02deafness or more accurately unilateral
  153. 5:05profound deafness. This is because if a
  154. 5:07device is placed on the deaf side, the
  155. 5:09vibration it creates travels across the
  156. 5:11entire skull and stimulates the ear on
  157. 5:14the other side, the side that does have
  158. 5:15hearing, it effectively rroots that
  159. 5:17sound, overcoming that head shadow
  160. 5:19effect and stops you missing an entire
  161. 5:22hemisphere's worth of sound. Whether
  162. 5:23that's someone calling you from your
  163. 5:25deaf side or traffic coming down the
  164. 5:27road without warning. Now, before any
  165. 5:29discussion of surgery, a trial with a
  166. 5:30non-surgical device is important. It's
  167. 5:33the only way for you to experience this
  168. 5:35unique way of hearing and for your
  169. 5:36aiology team to measure the potential
  170. 5:38benefit. And actually, this kind of
  171. 5:40device can even be a long-term solution
  172. 5:42for some people who actually want to
  173. 5:44avoid surgery altogether. The classic
  174. 5:46non-surgical bone conduction solution is
  175. 5:48the Baja on softband. A processor, the
  176. 5:51same one that you would use with a
  177. 5:52surgical implant, actually instead
  178. 5:54clicks onto a plastic plate and an
  179. 5:56elastic headband holds it firmly against
  180. 5:58the mastoid bone behind the ear. This is
  181. 6:00the starting point for babies and young
  182. 6:02children where time is precious to give
  183. 6:04them access to sound. The BHM contact
  184. 6:06mini is a further available device used
  185. 6:08by a number of aiology units now that's
  186. 6:10very low in cost. For many older
  187. 6:12children and adults, the cosmetic
  188. 6:13element to these devices may be a
  189. 6:15drawback. And so the sound arc made by
  190. 6:18the company Cockia seeks to address this
  191. 6:20with a more stylish lightweight frame
  192. 6:22that you can wear a bit like a pair of
  193. 6:24glasses holding that vibrating component
  194. 6:26in just the right place. Now for some
  195. 6:28this is a more cosmetically acceptable
  196. 6:29option but there are still some
  197. 6:31limitations in terms of headaches and
  198. 6:33whistling feedback from any non-surgical
  199. 6:35device. Now to avoid that pressure there
  200. 6:37is also an adhesive solution out there.
  201. 6:39The one that is medically available is
  202. 6:41the adhair made by Medel and this uses a
  203. 6:43sticky adhesive pad each day on the skin
  204. 6:46behind your ear onto which you can click
  205. 6:48an external processor. Now, the benefit
  206. 6:50of that is that there is no pressure and
  207. 6:52headaches, but the limitation is that
  208. 6:54there is only so much volume you can
  209. 6:56possibly deliver through a device held
  210. 6:58on by a band or stuck to bone with an
  211. 7:00adhesive. The key takeaway here is that
  212. 7:02while these devices are absolutely
  213. 7:04fantastic for a trial, they do have
  214. 7:05limitations in terms of wearability and
  215. 7:08power. And so if a trial has been a
  216. 7:09success and you find yourself thinking,
  217. 7:11well, I love the sound, but I don't
  218. 7:13really want to wear this device or you
  219. 7:14need higher levels of clarity or
  220. 7:16stronger amplification. Then that's when
  221. 7:18you're ready to start considering a
  222. 7:20permanent surgical solution. So let's
  223. 7:22move on to surgical implants. And
  224. 7:24broadly speaking, these fall into two
  225. 7:26categories, perccutaneous and
  226. 7:28transcutaneous. Let's start with the
  227. 7:30original. And in terms of pure sound
  228. 7:32transmission, the most direct method
  229. 7:34that is perccutaneous implants.
  230. 7:36Perccutaneous means an implant that
  231. 7:38shows through the skin. These are often
  232. 7:40known as bone anchored hearing aids or
  233. 7:43baras for short. The surgery involves
  234. 7:45placing a small titanium implant into
  235. 7:47the skull bone. Attached to this is a
  236. 7:49connector called an abutment which
  237. 7:51passes through a tiny opening in the
  238. 7:53skin. Once healing is done, the sound
  239. 7:55processor just clicks directly onto this
  240. 7:57abutment. And this direct connection is
  241. 7:59the system's greatest strength. There's
  242. 8:00no skin or soft tissue to dampen those
  243. 8:03vibrations. It's pure efficient energy
  244. 8:05transfer. This provides exceptional
  245. 8:06sound quality and gives it the most
  246. 8:08power, making it suitable for people
  247. 8:10with more significant hearing losses.
  248. 8:12The current most powerful perccutaneous
  249. 8:14bara is even suitable for patients with
  250. 8:16bone conduction hearing levels as low as
  251. 8:1965 dibels on that aiogram and that makes
  252. 8:21it the strongest category of bone
  253. 8:23conduction implant. Now, in terms of
  254. 8:25commercial brands, there are two brands
  255. 8:27of perccutaneous bara. The bara system
  256. 8:29made by coccleia and the ponto made by
  257. 8:32Oticon Medical. And they both work in
  258. 8:34the same way with an abutment showing
  259. 8:36through the skin. Now the surgery itself
  260. 8:37for perccutaneous bara has evolved
  261. 8:39hugely over the years. Prior to 2012 it
  262. 8:42involved a big operation usually under a
  263. 8:44general anesthetic and patients could
  264. 8:46usually expect to lose quite a bit of
  265. 8:47hair around the implant. Since around
  266. 8:492012 that changed quite significantly
  267. 8:51and the operation was done under local
  268. 8:53using a small incision and very recently
  269. 8:55we've moved on even more of a leap and
  270. 8:57Ottoon medical have designed a technique
  271. 8:59called mono which we use for all our
  272. 9:02adult patients and this has great
  273. 9:03potential because it actually uses a
  274. 9:05tiny circular skin biopsy punch rather
  275. 9:08than making a cut at all and that has
  276. 9:10the benefits of faster healing and
  277. 9:12better cosmetic results. So for adults,
  278. 9:15both Ponto and Bara can be performed as
  279. 9:17an outpatient procedure and this takes
  280. 9:19as little as 10 to 15 minutes per side.
  281. 9:21Now, now with all that said, the idea of
  282. 9:23a permanent metal screw showing through
  283. 9:25your skin isn't for everyone. It's going
  284. 9:27to require daily cleaning. And although
  285. 9:29much more uncommon compared to previous
  286. 9:31generations, there is still a risk of
  287. 9:34skin irritation and even a risk of the
  288. 9:36implant falling out. And this has led to
  289. 9:38the development of our second category,
  290. 9:40transcutaneous implants. Now, in a
  291. 9:42transcutaneous implant, the vibrating
  292. 9:43part of the implant is actually buried
  293. 9:45under the skin. And since 2025, we now
  294. 9:48have three options available in this
  295. 9:49category that I'm going to show you.
  296. 9:51With a transcutaneous device, an
  297. 9:52internal implant is secured to the bone
  298. 9:54with an external processor worn outside
  299. 9:56of the head, held through the skin via a
  300. 9:59magnetic connection. When you take the
  301. 10:00processor off, the skin is completely
  302. 10:02intact, and so it's therefore invisible
  303. 10:05to the outside world. There's no
  304. 10:07cleaning, no wound. And there is a huge
  305. 10:09lifestyle and cosmetic advantage for
  306. 10:11many because of that. Now these devices
  307. 10:13are termed active meaning the part that
  308. 10:15creates the vibration is the internal
  309. 10:17part under the skin and this makes them
  310. 10:19more effective than some of the older
  311. 10:21passive magnetic systems that you might
  312. 10:23have heard of such as Bajar attract and
  313. 10:25sophono. So let's get into those three
  314. 10:27options that I said we have available.
  315. 10:28First we have the bone bridge from the
  316. 10:30company Medel. Now, Medel brought the
  317. 10:32first active transcutaneous implant to
  318. 10:34the market when they bought out the bone
  319. 10:36bridge. And the internal implant here
  320. 10:38uses what we call a bending wave
  321. 10:40transducer, which is secure to the bone
  322. 10:42with two screws. The external processor
  323. 10:45is called the Samber, and we've used it
  324. 10:46reliably and successfully for a number
  325. 10:48of years now. We've been doing a slimmer
  326. 10:50version two of the bone bridge implant
  327. 10:52since 2019, and this is when it first
  328. 10:54became mainstream. It was an exciting
  329. 10:56technology because it was the first
  330. 10:58mainstream active transcutaneous bone
  331. 11:00conduction implant available for
  332. 11:02patients who until that point hadn't
  333. 11:04really wanted a perccutaneous device.
  334. 11:06Now to have a bone bridge you need to
  335. 11:08have bone conduction hearing levels on
  336. 11:09your aiogram of at least 45 dibels. It's
  337. 11:12also worth noting that streaming to your
  338. 11:14phone with this implant will require a
  339. 11:16separate additional device worn on a
  340. 11:18pendant known as the sambber to go. And
  341. 11:20we typically also need a CT scan to
  342. 11:22assess the volume of bone required to
  343. 11:24house the implant in the skull. And
  344. 11:26because of that, this may affect the
  345. 11:28positioning of the implant. Because the
  346. 11:30amount of bone needed to house the
  347. 11:31actual implant in the skull is more than
  348. 11:34compared to a perccutaneous bara. There
  349. 11:36are a few patients, particularly those
  350. 11:37who have had previous extensive surgery
  351. 11:40for whom fitting this implant in the
  352. 11:42place we want within the skull is a bit
  353. 11:43tight. And that brings us on to our next
  354. 11:46implant option, the coccleia oia. The
  355. 11:48OIA has been pretty popular since we
  356. 11:50started offering it in 2021. It aims to
  357. 11:52provide greater transcutaneous
  358. 11:54amplification whilst only requiring the
  359. 11:57same bony footprint in the skull as the
  360. 11:59perccutaneous bara. The internal implant
  361. 12:01uses what's known as pizzo electric
  362. 12:04power and so instead of a motor
  363. 12:05vibrating, it uses material that expands
  364. 12:08and contracts creating vibration. Now
  365. 12:10this is thought to have some benefits in
  366. 12:12terms of being able to provide more
  367. 12:13power in a given size implant and
  368. 12:15amplify some higher frequencies more
  369. 12:17effectively and we see this in the
  370. 12:19candidacy range which includes patients
  371. 12:21with bone conduction thresholds as low
  372. 12:23as 55 dibels compared to 45 dibels for
  373. 12:26the bone bridge. The external oio sound
  374. 12:29processor has direct streaming
  375. 12:30capabilities without an additional
  376. 12:32device and we've had very good feedback
  377. 12:34from patients for its performance
  378. 12:36particularly in noise. The main caution
  379. 12:38to mention with regards to the OIA is
  380. 12:40that with all that power, it is the
  381. 12:42largest of all transcutaneous implants.
  382. 12:44Now, with patients who have thin skin,
  383. 12:46this can manifest as quite a notable
  384. 12:48bump on the side of the head that
  385. 12:49recipients sometimes say they can see
  386. 12:51and feel. The size of the OIA also
  387. 12:53brings some limitations in where we can
  388. 12:55position it on the skull. And what we've
  389. 12:57noticed is that this is leading to us
  390. 12:59needing to position it higher and more
  391. 13:01noticeably when compared to some of the
  392. 13:03other implants. And that brings us on to
  393. 13:05our final transcutaneous implant, the
  394. 13:08newest on the block, which we started
  395. 13:09offering in 2025. This is the Centio
  396. 13:12from Oticon Medical. Now, we are very
  397. 13:14early into our experience with this
  398. 13:16device, but I think it's going to be
  399. 13:17pretty popular because it has the same
  400. 13:19amplification power as the bone bridge
  401. 13:21and is also noticeably slimmer in size
  402. 13:23compared to the OIA. This is a sweet
  403. 13:25spot for surgeons as the size of the
  404. 13:26implant combined with shallower bony
  405. 13:29depth needed means less uncertainty over
  406. 13:31positioning during the operation. The
  407. 13:33processor looks stylish and Ottoon I
  408. 13:35guess like all manufacturers are very
  409. 13:36proud of their sound processing
  410. 13:38technology which they say has benefits
  411. 13:40in terms of sound clarity and
  412. 13:42conversation in noise. Now at the moment
  413. 13:44we're offering this implant to adults
  414. 13:45and older children who have bone
  415. 13:47conduction hearing of at least 45 dibels
  416. 13:50or better. However, with that said,
  417. 13:52Ottoon Medical have made us aware that
  418. 13:54the internal component is built with
  419. 13:56capability for more power in the future,
  420. 13:58and there is definite talk of a future
  421. 14:01larger external processor being
  422. 14:03compatible and being able to offer
  423. 14:04greater power and reserve for patients
  424. 14:06with worse levels of bone conduction
  425. 14:09hearing thresholds on their aiogram. I
  426. 14:11also suspect the age licensing will drop
  427. 14:13to younger ages as more studies are
  428. 14:15completed. As we gather more long-term
  429. 14:17data, I'll aim to post updates via
  430. 14:19social media. So do feel free to
  431. 14:21subscribe for that and for other videos
  432. 14:23about hearing loss treatments and
  433. 14:25general insights as an ENT surgeon. Now
  434. 14:27the surgery for all these active
  435. 14:28transcutaneous devices is more involved
  436. 14:30than for a perccutaneous implant. Most
  437. 14:32will require a general anesthetic
  438. 14:34meaning you'll spend most of the day in
  439. 14:35hospital and typically the surgery can
  440. 14:37take 45 to 60 minutes or less.
  441. 14:39Technically all of the implants could be
  442. 14:41installed with local anesthetic alone.
  443. 14:44But this is something to discuss with
  444. 14:45your surgeon based on your individual
  445. 14:46factors. And it's fair to say that most
  446. 14:48of these are put in under general
  447. 14:50anesthetic. Okay, so now for the most
  448. 14:52important part of the video. Which
  449. 14:53should you choose? Perccutaneous or
  450. 14:56transcutaneous? A direct abutment or a
  451. 14:59hidden magnet? All of the devices I've
  452. 15:00mentioned are fully funded on the UK
  453. 15:03National Health Service, and you can
  454. 15:04have one or two implants depending on
  455. 15:06what you need. All the implant
  456. 15:07processors have a range of colors to
  457. 15:10choose and customize, and there are
  458. 15:11third party stickers that you can
  459. 15:13accessorize with, too. So, what else is
  460. 15:15important when making the decision?
  461. 15:17Well, I'm now going to give you what I
  462. 15:18think are the five biggest
  463. 15:19considerations that I think will help
  464. 15:21you choose your category. Let's break
  465. 15:23down the pros and cons in details.
  466. 15:25Number one, power and future proofing.
  467. 15:27This is about your aiogram. A
  468. 15:29perccutaneous systems direct link will
  469. 15:31give it the widest fitting range. It can
  470. 15:34handle more severe conductive and mixed
  471. 15:36hearing losses. Now, this also gives you
  472. 15:38more reserve. Now, as we age, our inner
  473. 15:41ear function tends to slowly decline
  474. 15:43naturally. And so, a more powerful
  475. 15:44implant means it's more likely to still
  476. 15:47be sufficient for your needs in 10, 15,
  477. 15:50or 20 years time. Now, with that said,
  478. 15:52the transcutaneous implants we have are
  479. 15:54still very powerful and quite suitable
  480. 15:56for the vast majority of candidates. But
  481. 15:59if the bone conduction hearing levels on
  482. 16:00your aiogram are close to that line, you
  483. 16:03might want to consider choosing the
  484. 16:04device that's going to offer you a
  485. 16:06little room for your hearing to worsen
  486. 16:08and give you the maximum longevity.
  487. 16:10Number two, lifestyle, cosmetics, and
  488. 16:13daily care. Now, on the face of it, the
  489. 16:14obvious question might be, why would I
  490. 16:16want an implant showing through my skin
  491. 16:18if I could qualify for one that's not
  492. 16:20visible? With a transcutaneous implant,
  493. 16:22after all, no one knows you have an
  494. 16:23implant when the processor is in your
  495. 16:25pocket. There's no daily cleaning
  496. 16:27routine. However, there is a trade-off.
  497. 16:29The external processes for
  498. 16:30transcutaneous implants are inherently a
  499. 16:33bit thicker and bulkier to house the
  500. 16:35magnet, and that can create a bit more
  501. 16:37of a bulge under the hair. What we found
  502. 16:39through doing these is that we've had to
  503. 16:41end up sighting the processor slightly
  504. 16:43higher on the skull rather than tucked
  505. 16:45away behind the ear. And so, a solution
  506. 16:47that you may have chosen for being more
  507. 16:49discreet actually becomes more
  508. 16:51noticeable when the implant is being
  509. 16:53worn. Now, a perccutaneous abutment is
  510. 16:55always there, of course, but the
  511. 16:56processor itself can be smaller and more
  512. 16:59discreet. The downside to perccutaneous
  513. 17:01implants is that they do require more
  514. 17:03daily care. And this is simple enough. A
  515. 17:05quick clean with a soft wipe like
  516. 17:07cleaning around a piercing, but it is a
  517. 17:08daily commitment and neglecting this can
  518. 17:11run the risk of perpetual wound issues
  519. 17:13and even visits to the hospital for
  520. 17:15nursing attention, creams, and even the
  521. 17:17risk of needing it removed. Number
  522. 17:19three, retention and skin issues. Now,
  523. 17:21this is the other side of the coin. A
  524. 17:23perccutaneous device clicks on. It's
  525. 17:25incredibly secure. It's very difficult
  526. 17:26to knock off, whilst a transcutaneous
  527. 17:28device is held on by a magnet. Now,
  528. 17:31magnets are strong, but even a hard
  529. 17:32knock or even pulling a jumper over your
  530. 17:34head can sometimes dislodge it. Now,
  531. 17:36this can be a concern for very active
  532. 17:38people or for children, and processor
  533. 17:40loss is an issue for some. Now, we can
  534. 17:42adjust the magnet strength, but a magnet
  535. 17:43that's too strong can cause pressure and
  536. 17:46redness and pain on the skin. So, it is
  537. 17:48a fine balance. Number four, having
  538. 17:50surgery and the recovery afterwards. As
  539. 17:52we've said, perccutaneous surgery is
  540. 17:54quicker and can often be done under
  541. 17:56local anesthetic. It's less invasive,
  542. 17:58and because of this, it's a popular
  543. 17:59option for people who have been on a bit
  544. 18:01of a difficult journey through multiple
  545. 18:03surgeries for chronic middle ear disease
  546. 18:05and just simply want a solution that's
  547. 18:07one and done, minimally disruptive to
  548. 18:09their schedule, minimal time off work.
  549. 18:11Transcutaneous surgery typically
  550. 18:13requires a general anesthetic, although
  551. 18:15do discuss this with your individual
  552. 18:17surgeon. With a perccutaneous abutment,
  553. 18:18we will usually wait between four and
  554. 18:20eight weeks for the skull to fully
  555. 18:22integrate with the titanium implant.
  556. 18:24With a transcutaneous implant, on the
  557. 18:26other hand, you can sometimes be
  558. 18:28switched on from as little as 2 to 4
  559. 18:30weeks following the operation. And
  560. 18:31finally, number five, and perhaps a big
  561. 18:33one, the MRI shadow. Now, this is an
  562. 18:35important consideration. You will read
  563. 18:36and be told that all of these devices
  564. 18:38are safe if you're needing an MRI scan,
  565. 18:40but that transpires in different ways.
  566. 18:43With a perccutaneous implant, you just
  567. 18:45take the processor off and you're good
  568. 18:46to go. The tiny titanium screw is safe
  569. 18:49in an MRI scanner up to three Tesla. It
  570. 18:52creates a very small artifact or shadow
  571. 18:53on the scan and this is unlikely to
  572. 18:55interfere with any diagnosis on a future
  573. 18:57brain scan that you might need. Now,
  574. 18:59with the transcutaneous implant, things
  575. 19:00are different. The internal magnet is an
  576. 19:03issue. The Bonebridge, OIa, and Centio
  577. 19:05all enable the ability to have an MRI
  578. 19:07safely. For Bonebridge and Centio, you
  579. 19:09can have an MRI up to 1.5 Tesla. And for
  580. 19:12the OIA, it's three Tesla. And sometimes
  581. 19:14radiographers will employ special
  582. 19:16headband protections just for extra
  583. 19:18measure. But critically, and perhaps
  584. 19:19more importantly, all of these magnetic
  585. 19:21implants create a significant shadow, an
  586. 19:24MRI brain scan, which can obscure the
  587. 19:26view of your brain on that side. Now,
  588. 19:28this is a vital consideration if you
  589. 19:30have a condition that might require a
  590. 19:32future MRI brain scan. It's particularly
  591. 19:34crucial for patients who have had
  592. 19:36chronic middle ear disease, for example,
  593. 19:37who may be relying on future MRI
  594. 19:40scanning to detect a recurrence of the
  595. 19:42disease. Now, in a way, that immediately
  596. 19:44cuts the decision in half for a large
  597. 19:46number of people who are choosing a bone
  598. 19:47conduction device after having what we
  599. 19:49call cholesttoma surgery. So, I've given
  600. 19:52you the five most important factors that
  601. 19:54I think will influence your
  602. 19:55decision-making over a bone conduction
  603. 19:57implant. And armed with that knowledge,
  604. 19:58hopefully you're going to have a clearer
  605. 19:59idea of which implant is going to fit
  606. 20:02with your specific preferences and
  607. 20:03priorities. Now, hopefully I've given
  608. 20:05you the tools to now have a really
  609. 20:07highquality discussion with the team
  610. 20:09looking after you. However, there is
  611. 20:10more. And for those of you that really
  612. 20:12like doing your research, I'm now going
  613. 20:14to run through eight other frequently
  614. 20:16asked questions that sometimes influence
  615. 20:18patients when figuring out which bone
  616. 20:20conduction implant is best for them.
  617. 20:21Number one, my anatomy. Based on my bone
  618. 20:24thickness and the position of the vital
  619. 20:26structures, am I a candidate for all
  620. 20:28implant types? And will there be any
  621. 20:30implications on where it's positioned? A
  622. 20:32CT scan is sometimes needed to answer
  623. 20:34this question, especially for the
  624. 20:35transcutaneous devices which have a
  625. 20:37larger internal footprint. Furthermore,
  626. 20:39if I need implants for both ears, am I
  627. 20:42able to have both during the same
  628. 20:43operation or does it need to be done one
  629. 20:45at a time? Your surgeon may have a
  630. 20:47reason for recommending one or the
  631. 20:49other. Number two, connectivity. If I
  632. 20:51use an iPhone, Android, will this device
  633. 20:54stream directly to my phone? And if not,
  634. 20:56which extra streaming device will I need
  635. 20:59and what will it look like? Other
  636. 21:00questions include, what is the app like
  637. 21:03to use? Do I have any more niche
  638. 21:04requirements? For example, like if I'm a
  639. 21:06musician in a band for this, it's worth
  640. 21:08going to the manufacturer's websites
  641. 21:10yourself as there willistically be
  642. 21:12limited time in your aiology
  643. 21:13appointments for this. And do check the
  644. 21:15latest compatibility list for your exact
  645. 21:17phone model and operating system. Number
  646. 21:19three, the other ear. If I already wear
  647. 21:22a hearing aid in my other ear, will this
  648. 21:24device be compatible with a conventional
  649. 21:26hearing aid in my other ear if I ever
  650. 21:28need one? Your aiologist will help you
  651. 21:30answer that question. Number four,
  652. 21:31dexterity and batteries. Can I try
  653. 21:33holding and attaching dummy versions of
  654. 21:35the processor? How easy is the battery
  655. 21:37change? Is it rechargeable or
  656. 21:39disposable? What's the typical battery
  657. 21:41life for children? Is the battery
  658. 21:43compartment tamperproof? Number five,
  659. 21:45helmets and headwear. I regularly wear a
  660. 21:47cycling helmet, hard hat, headscarf. How
  661. 21:50will I know which processor type will
  662. 21:51work with this? Can we trial a position?
  663. 21:53Number six, age licensing. Are there any
  664. 21:55age restrictions on some of these
  665. 21:57devices? Some are not licensed for very
  666. 21:59young children, and are there any
  667. 22:00circumstances that would necessitate an
  668. 22:02offlic decision? Number seven,
  669. 22:04accessories. What accessories come as
  670. 22:07standard? Things like a remote
  671. 22:09microphone or a TV streamer can make a
  672. 22:11huge difference, and the bundles offered
  673. 22:13by each company can vary. And finally,
  674. 22:15number eight, could a middle ear implant
  675. 22:18be an option? Now, an active middle ear
  676. 22:20implant is a different type of implant,
  677. 22:23but there is often some overlap, and
  678. 22:25many patients could have either a bone
  679. 22:27conduction implant or this as an
  680. 22:29alternative. Now, if you think this
  681. 22:30might be the case for you, then it's
  682. 22:32worth asking if that type of implant
  683. 22:34might be suitable. It's particularly
  684. 22:36good for people who have hearing
  685. 22:38problems related to their ear canal, but
  686. 22:40do still have a healthy middle ear
  687. 22:42space. The currently available option we
  688. 22:44have is the vibrant soundbridge made by
  689. 22:47Medel and I've covered that implant in
  690. 22:49an entirely separate video which I'll
  691. 22:51link to. The final important thing I
  692. 22:52should say is to remember that your
  693. 22:54recommendation will come from a
  694. 22:56multidisciplinary team. This isn't just
  695. 22:58a surgeon's decision or an aiologist
  696. 23:01decision. It's a big deal for you which
  697. 23:02means it's important to us that we get
  698. 23:04it right and it's sometimes a complex
  699. 23:06weighup. As a minimum for a bone
  700. 23:08conduction implant decision, the
  701. 23:10recommendations will need to be from at
  702. 23:12least both a surgeon and an aiologist,
  703. 23:14but may also involve a speech therapist,
  704. 23:16a teacher of the deaf, a psychologist,
  705. 23:19and a radiologist. The role of your team
  706. 23:21will be to help you understand what's
  707. 23:23technically suitable. The whole process
  708. 23:25is then enriched if you're able to help
  709. 23:27your team understand what works best for
  710. 23:29your life and your individual
  711. 23:31circumstances. Now, I've spent a lot of
  712. 23:32time putting together all of this
  713. 23:34information into a single comparison
  714. 23:37table, which I hope will be useful for
  715. 23:39both patients and clinicians around the
  716. 23:41world that work with these devices. So,
  717. 23:43that's a complete deep dive into the
  718. 23:45world of bone conduction hearing
  719. 23:46implants in 2025. This tech evolves
  720. 23:49almost every year, and the challenge is
  721. 23:51to make sure patients are given access
  722. 23:53to all the devices that might be
  723. 23:55suitable. Now, as you can see, there's
  724. 23:57no single best device, but there is
  725. 23:59almost certainly a best device for you
  726. 24:02based on your hearing, your lifestyle,
  727. 24:04and your priorities. So, I hope this
  728. 24:06video helps patients and also helps
  729. 24:08teams around the country save time and
  730. 24:10enhance their pre-operative counseling.
  731. 24:12Hearing is precious, as I'm always
  732. 24:14saying, and it can be the window to your
  733. 24:15social life, professional life, family
  734. 24:17life, and mental health. And that is
  735. 24:19something definitely worth investing in.
  736. 24:21So, please do share this video and
  737. 24:23please do leave a comment letting me
  738. 24:25know how you came across this video and
  739. 24:28also let me know of all the key factors
  740. 24:30we've discussed which do you think is
  741. 24:32the most important? Thanks for watching.
