Seventy‐four revision stapedectomies performed consecutively over 10 years (1986 to 1995) were reviewed retrospectively. The most common intraoperative findings were incus erosion, prosthesis displacement, and oval window closure. Incus erosion was more frequently associated with multiple revisions. The postoperative results were reported using the conventional method (postoperative air minus preoperative bone) as well as the guidelines recently published by the American Academy of Otolaryngology‐Head and Neck Surgery (postoperative air minus postoperative bone), with success rates of postoperative air‐bone gap closure to within 10 dB after revision surgery of 51.6% and 45.6%, respectively. Patients with persistent conductive hearing loss(large residual air‐bone gaps) after primary stapedectomy had poorer postrevision hearing results. Sensorineural hearing loss (defined as a drop in bone pure‐tone average of more than 10 dB) occurred in four cases (5.4%). The number of revision surgeries, variations in operative techniques using laser or drill, and the ossicle to which the prosthesis was attached did not statistically affect the postoperative air‐bone gaps. These results were compared with previously published data.
