OBJECTIVES: To describe the hearing outcomes in patients with far-advanced otosclerosis and to identify the best initial approach based on preoperative word recognition scores (WRS), pure tone averages (PTA), and radiological classification. STUDY DESIGN: Retrospective case review. SETTING: Academic neurotology tertiary referral center. PATIENTS: All patients (n = 58) with preoperative air conduction PTA less than 85 dB (HL), disyllabic WRS less than or equal to 50% at 60 dB (HL) with well-fitted hearing aids, and evidence of otosclerosis on CT scan, treated in our department over the past 20 years. INTERVENTIONS: Stapedotomy, cochlear implantation, or both. MAIN OUTCOME MEASURES: Postoperative WRS after a minimum of 12 months' follow-up, percentage of patients with WRS greater than 50%. Reliability of air and bone conduction PTAs and WRS in predicting failure of stapedotomy. RESULTS: Fifty-eight patients were divided into three groups: group I, primary stapedotomy (n = 32); group II, primary cochlear implantation (n = 9); and group III, secondary cochlear implantation (with a previous history of stapedotomy) (n = 25). The mean postoperative WRS were 50.6% (± 34), 75% (± 17), and 72% (± 20), respectively. Sixty percent of patients in the stapedotomy group had a postoperative WRS greater than 50% requiring no further treatment, compared to 85% for cochlear implant recipients. No specific predictive factors for stapedotomy outcome could be identified. Surgical difficulties during cochlear implantation were significantly higher in patients with advanced radiological stage. CONCLUSION: Although cochlear implantation gives better overall results, stapedotomy with hearing aids can still be very effective in the management of patients with far-advanced otosclerosis. It should therefore be proposed as a first-line treatment.
