Otosclerosis

Otosclerosis

This is an autosomal dominant condition of variable pene - trance in which excess bone is laid down around the footplate of the stapes, impeding mobility of the stapes and resulting in a conductive hearing loss ( Figure 51.23 ). A diagnosis should be suspected in any patient with a conductive hearing loss and a normal tympanic membrane. The trea tment options are simple reassurance, a conven - tional hearing aid, a stapedotomy operation or bone conduc - - tion hearing aid ( Figure 51.24 ). Otosclerosis
