Diagnosing Sensorineural Hearing Loss and Options for Treatment — Transcript

Full transcript

1. 0:01hearing loss is an invisible disability
2. 0:04people live in silence currently there
3. 0:07are one and a half billion people with
4. 0:10hearing loss that's one out of six
5. 0:14individuals patients who come in with
6. 0:16hearing loss can be in very different
7. 0:18states of Mind depending on whether that
8. 0:21hearing loss was very recent or
9. 0:24gradually Progressive if hearing loss
10. 0:26was sudden and profound then people come
11. 0:30in devastated because it's shocking it's
12. 0:34a completely new experience it really
13. 0:36disturbs their very core their identity
14. 0:40and that's different than people who
15. 0:42have had gradually Progressive hearing
16. 0:47laws when it comes to hearing laws there
17. 0:49are two different kinds one is called
18. 0:52conductive and the other is called
19. 0:53sensory neural and to understand the
20. 0:56difference we can review how we hear
21. 0:59when sound comes in through the ear
22. 1:01canal where wax is made it vibrates the
23. 1:04eard drum which is located at the end of
24. 1:06that funnel that sets in motion the
25. 1:09smallest bones in the body they are
26. 1:11called the malas the incus and the
27. 1:13stapes which is the Latin for the hammer
28. 1:16the Anvil and the stir bones and then
29. 1:19these bones then set in motion fluids
30. 1:22within the inner ear the inner ear is an
31. 1:25organ encased deep in the bone and it
32. 1:28contains sensory cells called hair cells
33. 1:31and when they are activated they release
34. 1:34a neurotransmitter which is a chemical
35. 1:36that now sends a signal to the nerve and
36. 1:39now this electrical signal is sent all
37. 1:42the way to the brain and that's how we
38. 1:44hear so conductive hearing loss implies
39. 1:47that sounds are not conducted to the
40. 1:50inner ear that can be because there's a
41. 1:52hole in the eardrum or there is fluid
42. 1:55behind it normally this is an Airfield
43. 1:57space or there is something wrong with
44. 1:59these tiny bones and that's conductive
45. 2:02hearing loss sensory neural hearing loss
46. 2:04affects the inner ear where these super
47. 2:08delicate fine sensory cells and neurons
48. 2:10reside and all the other cell types in
49. 2:13the inner
50. 2:15ear unfortunately our treatment options
51. 2:19for sensory neural hearing loss are
52. 2:21currently limited to primarily two types
53. 2:24of devices either hearing aids or C-
54. 2:28clear implants and each works well at
55. 2:31one end of the extreme hearing aids
56. 2:33typically work for people with mild
57. 2:35hearing loss and clear implants are
58. 2:38reserved for people with severe to
59. 2:40profound hearing
60. 2:41loss the way we perform coar implant
61. 2:44surgery is that we insert the device
62. 2:48through a natural opening into the inner
63. 2:50ear which is called the round window
64. 2:52membrane and then insert it very gently
65. 2:55so that it goes along the length of the
66. 2:58ca C clear implants are not for everyone
67. 3:01because it's a surgical procedure and
68. 3:03like any surgical procedure it carries
69. 3:06risks and in surgery in general we
70. 3:08always consider the risk benefit ratio
71. 3:12currently an average user of a CER
72. 3:15implant gets a word recognition score of
73. 3:1960% so that means that if they are asked
74. 3:22to repeat words they repeat correctly
75. 3:2560% of the words and those who start
76. 3:29from zero
77. 3:30complete profound deafness or 20% or
78. 3:32even 30% and now jump up to 60% that's
79. 3:36great however if someone has higher
80. 3:39performance than that the risk of losing
81. 3:44the residual acoustic hearing that they
82. 3:46have is not justified by performing this
83. 3:49procedure at Stanford medicine we can
84. 3:52blend this compassionate skilled
85. 3:56personalized patient care with Cutting
86. 3:59Edge research
87. 4:00Our Hope for the future is to enable
88. 4:04options and cures for hearing loss or
89. 4:07the very least better treatment options
90. 4:10because hearing is such an essential
91. 4:12sense for human connectedness
