ABSTRACT

Stapedial otosclerosis is the most common type of otosclerosis causing stapes fixation with progressive low frequency conductive or mixed hearing loss and air-bone gap seen in pure tone audiometry. Many patients show Carhart’s notch which is a depression in bone threshold at 2000 Hz. It is mainly treated surgically; by stapedotomy which is the most efficient surgical procedure or by stapedectomy in some other cases. The aim of our study is to compare hearing results in patients underwent stapedotomy or stapedectomy for the treatment of conductive hearing loss due to otosclerosis. A retrospective analysis of hearing results of 45 patients underwent stapedotomy or stapedectomy at Otolaryngology Department, King Hussain Medical Centre between March 2020 and March 2022 were compared. In our study, we evaluated 13 patients who underwent stapedectomy and 32 patients underwent stapedotomy. The average age was 36.7 years for the stapedectomy cohort and 35.1 years for the stapedotomy group. There was 39% male in the stapedectomy group and 40% in the stapedotomy group. The median duration of illness prior to surgery was 27 months for both sets of patients. Regarding the ear affected by otosclerosis, 15% of the stapedectomy group had the right ear affected, compared to 16% in the stapedotomy group. Bilateral involvement was high, with 77% in the stapedectomy group and 78% in the stapedotomy group. We concluded in the last of our study that there were no significant differences in postoperative pure-tone average (PTA) or air-bone gap between the two groups of patients underwent either stapedotomy or stapedectomy. By these results, either procedure shows approximately same hearing results.
