In the video I saw the x-ray. Now I have a stupid question probably. I read articles but I am not certain. How does the implant stay in your head and not move? Does it screw into your skull? If so, doesn't that hurt forever? If not, why doesn't the CI move? I never saw a x-ray.
Edit: I used a different search and found articles about "bone glue", "bone cement", and "titanium clips". Reading these make me feel a little sick.
Also I am allergic to glue on athletic tape and surgical tape. Do some have allergies to bone glue?
Edit again: Studies show some are allergic to CIs - silicone etc. And with allergies the CI comes out of the skull. But very very rare (less than 0.001% I guess)
Example from Otology & Neurotology. 27(8):1078-1082, December 2006: Silicone Allergy: A New Cause for Cochlear Implant Extrusion and Its Management
Objective: We introduce silicone allergy as a rare cause for cochlear implant extrusion and discuss its management. - Results: Three known cases of cochlear implant extrusion as a result of silicone allergy have been noted from 1991 through 2004 in three cochlear implant programs in the United States. All three devices extruded, resulting in explantation of the old device and reimplantation with a new custom-made device eliminating the allergenic silicone component. Wound cultures were negative in all cases. All three patients experienced a delayed extrusion of their devices. Two of these patients had a test-proven allergy to the implant's silicone components, whereas the third patient was presumed to have a hypersensitivity solely on the basis of a clinical presentation.
Conclusion: We propose that silicone allergy is a rare cause of cochlear implant extrusion. Patients experiencing cochlear implant extrusion, particularly with a delayed onset and negative wound culture results, should be tested for silicone allergy.
