A Study of Interlay Grafting in Type 1 Tympanoplasty for Large Central Perforation

The objective of the study was to study the outcomes of interlay type 1 tympanoplasty in large central perforations in terms of graft uptake, hearing improvement and complications. Study included 150 symptomatic patients having large central perforation in tympanic membrane willing for surgery who later underwent tympanoplasty with or without cortical mastoidectomy. All the patients selected for study, were assessed for subjective and objective evaluation pre-operatively and then post-operatively after 4 months. The study was conducted at tertiary health care hospital. Type I tympanoplasty with Interlay technique for large central perforations is superior. The Interlay technique in Type I tympanoplasty has high success both in terms of graft uptake as well as ABG closure. In the view of the advantages it offers, it should be preferred over the other conventional techniques in patients with large central perforations for better results.
