Endoscopic Stapedotomy: Experience at the Hospital del Salvador

Abstract

Introduction: Otosclerosis is a metabolic bone disease of the otic capsule and the ossicles. It is a primary disease that may cause fixation of the stape and conductive hearing loss. Aim: To show endoscopic stapedotomy as a surgical alternative, and to compare the results with the stapedotomy using microscope. Material and method: Clinical records were reviewed of patients treated surgically in our department from January 2012 to June 2014 with suspected otosclerosis. 35 patients were obtained, 25 using microscope and 10 using only endoscope. Results: Average operative time was 60 and 85 minutes to microscopic and endoscopic group respectively. Air-bone gap closureat 2 months was 100% for endoscopic and 92% for microscopic surgery. One patient of endoscopic surgery and two patients of microscopic surgery presented postsurgical dysgeusia. Conclusions: Endoscopic stapedotomyis a surgical alternative as it allows an excellent vision and understanding of anatomy; it can be performeddespite a curved and narrowexternalauditory canal (EAC), with a betterexposure.It also helps to reduce the milling of EAC with less damage to the chorda tympani. Hearing result is comparable to the microscope surgery.
