Modified Myringoplasty Technique (Tragal Perichondrium with Cartilage Islands Reinforced by Temporalis Fascia) versus Conventional Technique (Temporalis Fascia Graft): A Comparative Study

Abstract Introduction: Myringoplasty with cartilage island as graft material is a new technique that combines the benefits of both fascia and cartilage. Myringoplasty with cartilage island as graft material is a new technique that combines the benefits of both fascia and cartilage. This study was undertaken to compare the hearing outcome and tympanic membrane (TM) perforation healing between two groups using two-layer graft consisting of temporalis fascia over a second graft of tragal perichondrium with attached cartilage islands in one and a single-layer conventional temporalis fascia graft in second. Aims and Objectives: The purpose of the study is to demonstrate the anatomical and functional results of myringoplasty with autologous temporalis fasciaplus tragal perichondrium with intact cartilage islands in comparison with the commonly used temporalis fascia alone. Materials and Methods: This study was conducted at Government Medical College Anantnag Department of ENT and HNS. A total of 51 patients were included and divided into two groups. Patients were selected according to lottery method. Surgery was done by single surgeon on all patients. All statistical analyses were conducted using IBM SPSS Statistics for Windows, version 20 (IBM Corp., Armonk, NY, USA). Results and Discussion: The average air–bone gap (ABG) preoperative and postoperative is 24.9 ± 10.8 and 14.8 ± 8.3 in modified technique, while in conventional techniques it is 22.37 ± 6.6 and 15.7 ± 7.3, respectively. The difference in the two groups was not found to be statistically significant. Hence, in terms of ABG closure, both grafts were comparable. Conclusion: From the present study, we conclude that the myringoplasty techniques could be modified with confidence by individuals depending on what works best for each. Using additional graft support materials may increase the success rates in myringoplasty in terms of graft healing time, residual perforations, and possible TM retractions in the future.
