A PROSPECTIVE OBSERVATIONAL COMPARATIVE STUDY FOR POST OPERATIVE RESULTS IN ENDOSCOPIC TYMPANOPLASTY V/S MICROSCOPIC TYMPANOPLASTY

Abstract

Objective: Chronic suppurative otitis media is a widespread disease in developing countries. Hence treating CSOM with surgical treatment by tympanoplasty is the commonest procedure in ENT practice. In this study we aim to study the advantages and disadvantages of microscopic and endoscopic tympanoplasty. This study also aims to compare the merits and demerits of microscopic and endoscopic tympanoplasty. A Prospective Subjects And Methods: observational study for endoscopic tympanoplasty and microscopic tympanoplasty was conducted on 102 patients of age 20-60 years attending OPD and admissions under the Department of otorhinolaryngology and M.Y.H Hospital, Indore. Subjects with dry central perforation due to CSOM were selected for microscopic tympanoplasty. Similar subjects were selected for Endoscopic tympanoplasty except those with tortuous anatomy of external ear canal. Patients with unsafe CSOM, SNHL, and active infection were excluded. In our study majority (44%) of patients Results: belonged to age group of 25-35 years. Most of the patients were having medium central perforation ( MCP) (32%) followed by subtotal perforation (22.5%). Small central perforation (SCO) 19%, Large central perforation (LCP) 18%, Total perforation 10% respectively. According to quadrant involving perforation which is mainly AIQ, followed by Anterior superior quadrant ( ASQ), Posterior inferior quadrant (PIQ) and posterior superior quadrant (PSQ). Mean operative time for Endoscopic tympanoplasty procedure was 56+/-15 mins with SD of 12.05 and for microscopic tympanoplasty procedure was 117.8+/- 20 mins with SD of 7.17 having a p value (0.0003) which was found to be significant. Conclusion: In our study, we have concluded that endoscopic tympanoplasty scores over microscopic tympanoplasty. Endoscopic tympanoplasty has helped patients achieve faster recovery, a shorter hospital stay, and a lower financial burden, which was especially helpful for developing countries like ours. Unlike the microscope, the endoscope is easily transportable and hence is ideal for use in remote places to conduct ear surgery camps.
