Follow-up
The initial scheduled visit for follow-up was carried out 1 week after surgery where the covering gauze was removed, and antibiotic ear drops were prescribed for 1 week. Audiological assessment was done 3 months after surgery in line with the guidelines of the American Academy of Otolaryngology- Head and Neck Surgery Committee on Hearing and Equilibrium. Pre- and post-operative air conduction (AC) thresholds and bone conduction (BC) thresholds were estimated at the frequencies 0.5, 1, 2, and 3 kHz. To calculate the 3 kHz results, the results for 2 and 4 kHz had to be averaged. The air bone gap (ABG) was estimated by calculating the difference between AC and BC thresholds [
