Background: Tympanoplasty is a common operation performed by otolaryngologists worldwide. During the last 100 years various modifications in this surgical technique have come up because of continued efforts made by otologists all over the world to achieve the best surgical outcome. Objective: The aim of this study is to compare the surgical and audiological outcomes of anterior tucking and circumferential flap methods of type 1 tympanoplasty. Materials and Methods: This prospective randomized study included 100 patients who presented in the ENT outpatient Department of Bangalore Medical College and Research Institute with chronic otitis medialarge central perforation in an inactive stage. Patients were randomly allocated to two groups of 50 cases each. Group A contained 50 patients who underwent Type I tympanoplasty by circumferential flap method, and Group B contained 50 patients who underwent Type I tympanoplasty by anterior tucking method. Patients were followed up at the 3rd month postoperatively by otomicroscopy and pure tone audiometry (PTA), graft uptake and hearing gain were assessed. Results: There was a statistically significant mean hearing gain postoperatively compared to preoperative PTA in both techniques, among the two techniques, there was no statistically significant difference regarding hearing gain and graft uptake. Conclusion: Anterior tucking and circumferential flap methods of type 1 tympanoplasty are good regarding graft placement, graft uptake, and audiological outcome for chronic otitis media with large central perforation, especially with little or no anterior remnant of pars tensa.
