Abstract

Background: A retrospective study done on all otosclerotic patients who underwent stapes surgery between January 2019 and June 2022 in the department of otorhinolaryngology in a tertiary care hospital in North India. Material and Methods: Fifty four patients were enrolled in the study. The inclusion criteria of the study included patients in the age group of 18–55 years with conductive hearing loss and an intact tympanic membrane and an air–bone gap (ABG) of more than 30 dB. Diagnosis of otosclerosis is based on clinical history of progressive hearing loss and audiometric evaluation. Pure Tone Average shows typical conductive hearing loss pattern. Aim and Objective: Preoperative and 6 months postoperative audiological evaluation was conducted to understand the difference in hearing. The same surgical technique was used in all the cases, except that the dimension of the foot plate removed was different. Results: The mean age of patients in years who underwent stapes surgery was 31.6 ± 6.4 years. Out of the 54 patients, 24 (44.44%) were male and 30 (55.56%) were female. The number of patients who underwent large fenestra stapedectomy was 30 (55.56%) and who underwent small fenestra stapedotomy was 24 (44.44%). There was a significant improvement in the hearing parameters (PTA and ABG) in both the groups after surgery, but there was no significant difference between the small fenestra and large fenestra groups in terms of improvement in PTA and ABG. Conclusion: In conclusion, both small fenestra stapedotomy and large fenestra stapedectomy are safe and effective procedures for improving conductive hearing loss in otosclerosis patients.
