Long-Term Results of Tragal Cartilage Type 1 Tympanoplasty

Abstract

Aim: Tympanoplasty is one of the most frequently performed operations by ear, nose, and throat specialists. Surgical treatment of tympanoplasty aims to obtain a healthy ear membrane and minimise hearing loss. The purpose of this study was to evaluate the success of the graft and functional hearing outcomes of patients applied with tragal cartilage type 1 tympanoplasty operation in our clinic. Materials and Methods: This study included 43 patients who underwent tragal cartilage type 1 tympanoplasty operation between January 2016 and November 2020. A retrospective evaluation was made of the preoperative pure tone audiometry (PTA) values and the operative findings. In the follow-up examination, the graft status and PTA results were recorded. The graft success and improvements in hearing were evaluated in all the patients. Results: A total of 43 patients were evaluated, comprising 24 males and 19 females with a mean age of 31.2 years (range, 13-58 years). The operation was performed on the right ear of 22 patients and the left ear of 21. The tympanoplasty operation was performed with an endaural approach in 6 cases and a postauricular approach in 37. The mean follow-up period was 20.8 months (range, 12-39 months). The rate of graft success of all the patients was 88.4%. The mean air conduction threshold, air-bone gap, and bone conduction threshold values at 500, 1000, 2000, and 4000 Hz were determined to have statistically significantly decreased postoperatively in comparison with the preoperative values (p<0.05). Conclusion: In tragal cartilage type 1 tympanoplasty operations, high rates of graft success were obtained and a dramatic gain in hearing postoperatively.
