Aim: to study the efficacy of endoscopic stapedotomy in comparison to traditional microscopic stapedotomy. Methods: Fourty patients with otosclerosis were divided equally & operated upon using either microscopic or endoscopic stapedotomy from August 2019 to September 2021. Comparison depend on intraoperative parameters e.g. operative time, oval window exposure, chorda tympani nerve (CTN) injury and other intraoperarive complications. Postoperative parameters e.g. improvement of hearing, air bone gap (ABG), taste sensation & other postoperative complications also were used for comparison. Results: There was less operative time in group A than in group B which was statistically significant. There is statisticaly significant decrease in post-operative ABG when compared with pre-operative ABG in both groups. There is no statistical significant difference between studied groups as regarding CTN injury. There was no statistically significant difference between studied groups as regarding intraoperative or post-operative complications. Conclusion: postoperative hearing is better than preoperarive one in both groups. Postoperative complications such as CTN injury and taste disturbance were less in endoscopic than microscopic stapedotomy.
