ABSTRACT

Introduction: This study reviews the cases of stapedotomy and evaluates its effectiveness at improving hearing loss in patients with otosclerosis. Objectives: This study aims to hearing improvement after stapedotomy and evaluation of tinnitus. Materials and methods: Prospective study of patients who had clinical and audiometric diagnosis of otosclerosis from November 2016 to November 2017. Results: A total of 12 stapedotomy surgeries (unilateral) were studied. Average post-operative ABG for 0.5, 1 and 2 KHz showed that 50 % had complete closure of ABG (ABG < 10 dB) and 41.6% had closure of ABG to within 20dB. 91.6% had hearing improvement and 83.3% had ABG closure greater than 10 dB postoperatively. Only 8.3% had hearing deterioration. 41.6% of the patients reported complete remission of tinnitus. 33.3% of the patients had decreased and 8.3% had increased tinnitus. 16.6% had no change of tinnitus. Conclusion: Stapedotomy is an effective surgical procedure for the treatment of otosclerosis which leads to improvement in patient’s quality of life. A favorable hearing outcome can be obtained by the combination of experienced hands with minimal surgical trauma and appropriate surgical technique.
