To assess the post-operative cases of stapes surgery. To determine correction in hearing loss post surgery and changing trends over 50 years. In a retrospective observational study, 234 cases otosclerosis who underwent surgical management between 1973 and 2023 were assessed. A total of 234 cases were seen. Male:female ratio was 0.8:1. Most patients were in the age group 21–30. Left > right ear involvement was seen. Stapedotomy > stapedectomy was the surgical procedure done. More than 50% patients had around 30db improvement in audiometric evaluation post surgery. Most common complications were vertigo and nystagmus which were seen more post stapedectomy as compared to stapedotomy. Sensorineural hearing loss is a rare complication and was seen exclusively post stapedectomy. We conclude that stapes surgery is beneficial in improving hearing capabilities with no difference as per change in surgical approach. Stapedectomy being more radical has more predisposition to vertigo and nystagmus post surgery. Post-operative complications has reduced with course of time due to improvement in surgical equipments and pre-op investigations. [ABSTRACT FROM AUTHOR]
