Comparison between endoscopic and microscopic type 1 tympanoplasty using temporalis fascia graft

Abstract

Aim: is to compare the outcomes of endoscopic vs microscopic type 1 tympanoplasty in patients with central perforation in tympanic membrane with conductive hearing loss. Materials and methods: This study was conducted in the Department of Otorhinolaryngology, at a tertiary care hospital and medical college, Odisha. This study was a hospital based single centered simple randomised control trial. A total of 100 cases of CSOM randomised into endoscopic and microscopic assisted tympanoplasty group (50 each) after taking proper informed consent. The duration of study was from September 2019 - August2021. Results: Out of 100 surgeries, there was one failure of uptake of graft and the patient belonged to the endoscopic group. Operative time was significantly shorter in the endoscopic group as compared to the microscopic group. There was no significant difference in terms of graft uptake and hearing improvement among the two groups. Conclusion: In both microscopic and endoscopic Tympanoplasty have their own advantages and disadvantages, Endoscopic Tympanoplasty offers slight benefits over Microscopic Tympanoplasty in terms of shorter duration, less granulation, less post op pain, wide angled view but it has inherent disadvantages being a single handed procedure. Unlike microscope, endoscope is easily transportable, hence it can be ideally used in camps conducted in remote places
