Their average age was 28 (range 12-62) years. The follow-up period was 3 months in 20 cases, 6 months in 14 cases and 12 months in 7 cases.

According to 500-2000 Hz pure tone hearing average of the cases, while average air bone gap (ABO) was 40 dB preoperatively, 23 dB in 3^rd month, 17 dB in 6^th month and 14 dB in l2^th month postoperatively. Hearing gain (HG) over 10 dB was achieved 80% of the cases in 3^rd month, 86% in 6^th month and 100% in 12^th month postoperatively. No dead ears was detected.
