Background Otosclerosis is a primary localized disease of the bony otic capsule that is mainly localized to the stapedial footplate. Stapedotomy is the treatment of choice. The effect of stapes surgery on otoacoustic emissions is not sufficiently known. Objectives The aim of the present study was to assess changes in the middle ear dynamic characteristics, and to evaluate distortion product otoacoustic emissions (DPOAEs) in otosclerosis. Moreover, the study aimed to evaluate DPOAEs before and after stapes surgery. Patients and methods A total of 20 patients with otosclerosis and undergoing stapedotomy surgery were included in the study. Assessment was performed preoperatively, 1 week, 1 month, and 6 months postoperatively by using pure-tone average, tympanometry, and DPOAE. Results Significant improvement in the air–bone gap by pure-tone average was reported at 1 week and 1 month postoperatively, whereas 6 months postoperative hearing threshold remained the same as that of 1 month postoperative. The difference between preoperative and postoperative detection of DPOAE was not significant. Conclusion Conventional pure-tone audiometry remains the choice for evaluation of stapes surgery in patients of otosclerosis. The use of DPOAEs in the evaluation of a successful stapes surgery requires further studies including a larger number of patients.
