Is one of these two techniques: CO laser versus microdrill assisted stapedotomy results in better post-operative hearing outcome?

Objective: To evaluate hearing results and outcome using two different surgical techniques (microdrill and CO Laser fenestration) in the treatment of conductive hearing loss in patients with otosclerosis.

Study Design: Retrospective audiometric database and chart review from January 2005 until December 2016.

Setting: Two tertiary referral hospitals MATERIALS AND METHODS: Seven-hundred forty-two primary stapedotomy have been reviewed retrospectively in two referral hospitals.

A comparative retrospective study: hypoglossofacial versus masseterofacial nerve anastomosis using Sunnybrook facial grading system.

Introduction: The aim of our study is to compare the functional results between two surgical techniques for reanimation of facial paralysis: hypoglossal-to-facial versus masseteric-to-facial nerve anastomosis.

Methods: This is a retrospective study of 13 patients treated for complete facial paralysis in two medical tertiary centers. The patients were classified into two groups.
