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

Etiology for Otosclerosis

Otosclerosis is a condition that causes a gradual loss of hearing in one or both ears. It is believed to arise from a genetic disorder being transmitted from one generation to the next generation. There is evidence of variable expressivity, meaning the genetic disorder may not cause hearing loss in every individual. Many patients are carriers of the genetic disorder and never develop the disease. Factors that cause expression of the genetic alteration are unknown.
