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.

Paediatric tympanoplasty is regarded by many as being less successful than in adults due to higher incidence of otitis media. In our study, we are trying to determine the pre-operative conditions that influence the success of paediatric tympanoplasty and construct a prognostic index for the same.To determine which pre-operative conditions or surgical technique may influence the success of pediatric tympanoplasty and to construct a prognostic index for the same.40 children between 8-15 years were included in this prospective study between June 2018- August 2019 in Department of ENT, in our institution. Pure Tone Audiograms were recorded pre and post operatively.The positive outcomes measured were integrity of tympanic membrane, minimum of 10decibel gain in auditory threshold and air filled space in middle ear. Higher success rate was observed in cases with elder age group (12-15 years), shorter duration of ear discharge, longer period of dry ear and small size of perforation.Tympanoplasty in children is a current and controversial theme. We have made a novice attempt to define factors that predict success or failure in paediatric tympanoplasty.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
