To identify the causes of failure primary stapes surgery and to evaluate hearing results revision in a consecutive series 652 cases.Prospective nonrandomized clinical study.Tertiary referral center.Six hundred thirty-four patients who underwent operations from April 1992 December 2007 were enrolled this study.Preoperative postoperative audiometric evaluation using conventional audiometry, namely, air-bone gap (ABG), bone-conduction thresholds, air-conduction assessed. Postoperative audiometry was performed at 3, 6, 9, 12, 18, 24 months then annually for 15 years.The most frequently identified reason incus erosion (27.6%) prosthesis displacement (18.2%). The ABG closed 10 dB or less 20 63.4 74.6% cases, respectively. mean 4-frequency 11.5 as compared with 28 preoperatively (mean difference, 16.5 dB; 95% confidence interval [CI], 15.1-17.9 dB, p < 0.0001). thresholds 45.7 58.7 13 CI, 11.4-14.6 34 30.6 -3.5 -4.4 -2.5 A significant sensorineural loss (>15 dB) observed 2.9% cases series.Improvement conductive after initial unsuccessful can be accomplished further but is occasionally modest.
