Aims and Objectives: To study the outcomes of interlay tympanoplasty (Type I) in patients with large central perforations (inactive mucosal chronic otitis media [COM]) in terms of graft uptake and hearing improvement. Materials and Methods: The present study is an analysis of database of 500 patients of inactive mucosal COM with large central perforation, who had undergone Type I interlay tympanoplasty at Jain ENT Hospital, Jaipur, during the past 5 years. Results: The graft uptake rate in the present study was found to be 96.6%, and 95.4% of the patients reported an improvement in terms of hearing with the mean air-bone gap improving from 26.08 to 10.12 dB. Conclusion: Tympanoplasty done by interlay technique has excellent results both in terms of graft uptake and hearing improvement, with minimal complications.
