Patient Characteristics and Outcomes Following Conventional Small Fenestra Stapedectomy: A Retrospective Analysis

Verma N*, Dubey KK

The current study was undertaken to evaluate the results of stapedotomy over a three-year period at a tertiary hospital. We studied the case records, including demographic data and operative results, of patients with clinically suspected otosclerosis undergoing stapedotomy. Over a 3-year period, a total of 264 patients underwent small fenestra stapedectomy of which records were complete for 200 patients and were thus included for analysis. The procedure was done under local anaesthesia and used a 0.6 mm Teflon piston with sacrifice of the stapedius tendon. Air-Bone Gaps at speech frequencies of 500 Hz to 3 KhZ were averaged to calculate the Pure-Tone averages. This was done following the recommendations of the AAO-HNS and was done pre-operatively and post-operatively. 92/200 patients were male (46%) and 108/200 (54%) were female with an age range of 20-50 and a mean of 32 ± 7.78 years. The mean pre-operative Air-Bone gap was 46.1 ± 8.23. No patient had abnormal BC thresholds. After surgery, the mean air-bone gaps at 30 days, 90 days and 180 days were 28.84 ± 6.74, 18.32 ± 6.53 and 9.26 ± 4.49 dB. At six months’ follow-up, all patients had achieved Air-Bone Gap closure to within 25 dB while 104 patients (52%) had achieved closure to within 10 dB. While the study is retrospective in nature, our results reflect current thought that small fenestrastapedectomy remains an excellent surgical option in experienced hands for patients with otosclerosis.
