Endoscopic Stapedotomy: The Merits and Demerits
ثبت نشده
چکیده
Objective: In this study, we aimed to analyze and compare the outcomes and complications of endoscopic stapes surgery versus microscopic stapes surgery. Patients and Methods: This study is a comparative analysis of patients with conductive hearing loss who were going to undergo stapedotomy at department of otorhinolaryngology, faculty of medicine, mansoura university, egypt, between September 2015 and july 2016. The patients; diagnosed as having otosclerosis and full filled the selection criteria; were randomly divided into 2 groups. Group A included 28 patients who underwent microscopic surgery and group B included 14 patients who underwent endoscopic surgery using the nasal endoscopes. Results: The group A included 28 patients (aged 19 60 years) and the group B included 14 patients (aged 22 56 years). Mean follow-up durations were 4.5 months (1-8.5) in the endoscopic group and 5.5 months (1.5-8) in the microscopic group. The difference in preoperative and postoperative air-bone gap in two groups was statistically significant (p = 0.031). But there was no statistical difference for hearing results between two groups and the two techniques have similar audiological outcomes. The main merits of endoscopic stapedotomy are the good quality panoramic image, well identification and visualization of vital structures of the middle ear, minimal handling of chorda tympani nerve if needed with practically no curettage of bony wall. Conclusion: In the present series, we show that it is possible to perform stapes surgery using only the 4mm in diameter and 18 cm long endoscopes of different angulations, without major difficulties.
