Otosclerosis is a compound metabolic disease characterized by the proliferation of abnormal bone in the otic capsule and hearing loss. It is unique to the human temporal bone.

Basic Concepts of Surgery  The proliferation usually begins in late adolescence, just anterior to the fissula ante fenestram,1 continues for a number of years, and then stops. This proliferation follows a distinct pattern in that it is most frequently either confined to the anterior 30% of the footplate and oval window or widespread throughout the footplate and surrounding oval window.The purpose of surgery in otosclerosis is to create a permanent passageway for sound—from the middle to the inner ear—once again. The entire stapes can be mobilized at surgery in a large percentage of cases by various means, but the basic pathology remains essentially unchanged and all too often ankylosis of the stapes recurs.It has been demonstrated by Fowler
