Stapedectomy in tympanosclerosis, hearing results

ABSTRACT

The aim of the present study was to evaluate the results of using stapedectomy to treat tympanosclerosis fixation of the footplate. A retrospective review of tympanosclerosis of the oval window with stapes fixation, after undergoing surgery. Eight patients underwent stapedectomy for tympanosclerotic stapes. Postoperative post-op air-bone gap ABG closure to within 10 dB was achieved in 25% of cases. An ABG of less than 20 dB was obtained in 87.5% of cases. The mean preoperative pre-op ABGs were 31.09 dB, and post-op ABGs were 13.28 dB. Significant post-op improvement of air conduction thresholds more than, or equal to 20 dB was found in 62.5% of cases. No significant sensorineural hearing loss was seen in this series with a mean pre-op bone-conduction threshold BC of 23.43 dB and a mean post-op BC threshold of 16.25 dB. The mean follow-up period was 6.5 months
