ENDOSCOPIC STAPEDOTOMY- OUR EXPERIENCE
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 36
Abstract
BACKGROUND Otosclerosis is one of the commonest causes of non-suppurative conductive hearing loss. Small fenestra stapedotomy was first developed by Shea in 1962. After 50 years of first microscopic stapedotomy, endoscope-assisted stapedotomy was first described by Poe in 2000. Full endoscopic stapedotomy was performed by João Flávio Nogueira Júnior in 2008. There are few papers on endoscopic stapedotomy, so here we are doing a study of the endoscopic stapedotomy. The aim of this study is to analyse whether Endoscopic Stapedotomy is safer and less traumatic. MATERIALS AND METHODS It is a descriptive study. There were 40 patients who underwent Endoscopic Stapedotomy for otosclerosis. Preoperative and postoperative pure tone averages and air-bone gaps were compared. Perioperative and postoperative complications were noted. RESULTS The surgeries were performed with endoscope and relevant anatomical structures were visualised without difficulty. Audiologic improvement was achieved in 37 of 40 patients. Postoperative air-bone gap was within 10 dB in 28 ears and between 10 - 20 dB in 9 ears. Unfortunately, sensorineural hearing loss was observed in 1 patient and vertigo in 5 patients. CONCLUSION Endoscopic stapes surgeries are technically feasible, safe and promising. In this series, the main advantages were virtually no trauma to the chorda tympani nerve and excellent visualisation of middle ear. The disadvantages were the lack of stereoscopic vision, having to work with one hand only and steep learning curve.
