Otosclerosis

Otosclerosis is a condition in which the bones in the middle ear become fixed and immobile, leading to hearing loss (usually one-sided).

Diagnosis for Otosclerosis

A careful history, review of symptoms, and examination with an operating microscope can suggest the diagnosis of otosclerosis. An audiogram (hearing test) can confirm the existence of hearing loss consistent with otosclerosis. However, a definitive diagnosis cannot be made until the middle ear is visualized surgically. If the stapes bone is fixed and immobile, the diagnosis of otosclerosis is established.
