Study On The Outcome Of Endoscopic Tympanoplasty Versus The Conventional Method.

Abstract

BACKGROUND : Endoscopic tympanoplasty is an minimally invasive surgery for the repair of tympanic membrane with complete graft survival and hearing outcomes to the conventional microscopic surgery. This study was aimed to evaluate the success rate of endoscopic trans-canal closure of tympanic membrane perforation compared to the conventional post auricular approach using temporalis fascia and tragal cartilage as a graft. METHODS: Our study consisted of 50 patientswith chronic otitis media,with dry ear for last 2 months and all patients were between 18-50yrs of age.All selected patients were subjected to pre operative oto endoscopicand audiological assessment and underwent endoscopic trans canal tympanoplasty using temporalis fascia in some and tragal cartilage in some. RESULTS: Trans canal endoscopic surgery resulted in the successful healing of 97% whereas in conventional method successful healing was only up-to 92%. The average hearing gain was also significantly improved in endoscopic surgery compared to that of conventional method. When the operative time was considered the mean time in endoscopic method was lesser. All patients were followed up for a period of 3 months. CONCLUSION: Comparisons between these 2 groups focused on the surgical outcomes and restoration of hearing, including the duration of surgery. All patients were followed up for a period of 3 months. Using this method not only improves the cosmetic outcome but also reduces the post operative morbidity with shorter operative time.
