A New Method in Transcanal Medial Grafting Type-I Cartilage Tympanoplasty.

Abstract

To determine the surgical results of a modified technique for the tympanic membrane (TM) perforation repair and to compare this new technique with the traditional methods. An interventional study. Place and Duration of the Study: Department of Otolaryngology, Medicana International Hospital, Samsun, Turkiye, from June 2019 till June 2021. The study was conducted with 24 patients who underwent cartilage tympanoplasty. Pure-tone audiometry (PTA), preoperative and postoperative air and bone conduction hearing levels were determined. The mean values of air and bone conduction and air-bone gap (ABG) were recorded. Postoperatively, 23 grafts were intact, and one was perforated, perforation secondary to otomycosis in the first month postoperatively. Eight patients had previous unsuccessful tympanoplasty history. These patients' tympanic grafts were intact with this technique. Surgical success rate was 96.0%. Postoperative hearing gain was 12,8 dB. Functional success rate was 88.0%. Mean surgery time was 30 minutes. Patients easily continued their lives in one-week time after the surgery. The new modified cartilage tympanoplasty method had high surgical success, and good audiometric results were obtained.
