Interlay Type-1 Tympanoplasty with or Without Cortical Mastoidectomy in an Inactive Mucosal Chronic Otitis Media with Large Central Perforation: A Retrospective Comparative Study.

Unlabelled: Background: Chronic otitis media (COM) is a pathology involving the middle ear cleft characterized by discharging ear and a non-healing perforation in tympanic membrane. Different techniques have been used for closing the perforation but interlay myringoplasty has become popular among surgeons since the past few decades. Objectives: To evaluate and compare the success rate of Type-1 interlay tympanoplasty in large tympanic membrane perforation with or without cortical mastoidectomy in terms of graft take-up rate and improvement in hearing outcomes.
