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