Histologically proven cochlear otosclerosis with pure sensorineural hearing loss

Abstract

This paper discusses cochlear otosclerosis without stapedial fixation as a cause of sensorineural hearing loss. Because many cases of cochlear otosclerosis may remain undiagnosed, we believe that patients with a progressive sensorineural hearing loss and a family history of cochlear otosclerosis should be suspected of having cochlear otosclerosis. A positive stapedial reflex on-off effect or polytomographic findings help make the diagnosis. We prescribe sodium fluoride, calcium, and vitamin D for these patients in an effort to prevent progression of the loss.
