Abstract:
We report on a rare case of cochlear implantation in a patient affected by relapsing polychondritis (RP), which over time induced cochlear fibrosis/ossification and deterioration of previously excellent hearing performance. The clinical course was determined by CT scan, electrophysiology, and speech perception data. We conclude that RP is a severe autoimmune connective disorder that can cause profound sensorineural hearing loss. Cochlear implantation in these patients can provide excellent performance. Continuation of therapy may improve prognosis, but relapses involving inner ear structures can determine fibrosis/ossification of the modiolus and interfere with cochlear implant use.

Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...
