Abstract

Experiences related here were obtained while utilizing the partial stapedectomy technique for stapedial ankylosis in over 2,000 cases. This procedure allows for removal of the pathologic portion of the footplate and normal reconstruction of mucous membrane and endosteum at the oval window. It utilizes the posterior crus as a functioning ossicle. Except in unusual circumstances, prosthetic devices and tissue grafts were found to be unnecessary. This technique has given excellent long-term results in a large number of patients. In over 90% of the cases reported the air-bone gap has closed to within 10 decibels, and in 65% of the cases, the air-bone gap was overclosed. Although some patients have been followed as long as seven years, there has been threshold regression of 10 decibels or more from the point of highest postoperative gain in only 1.5% of cases. Results reported recommend this technique as a step toward a more physiologic solution to the problem of stapedial ankylosis.
