Abstract
Background: The study was conducted to assess hearing improvement and graft uptake rate in patients with an anteriorly extended tympanic membrane perforation who underwent endoscopic cartilage tympanoplasty. Aim: The study aims to assess the efficacy of endoscopic cartilage tympanoplasty in repairing an anteriorly extended tympanic membrane perforation. Methods: A total of 135 patients aged between 10 and 63 years with an anteriorly extended tympanic membrane perforation were included in this study. Patients with an active middle ear disease and ossicular abnormality were excluded. Pure-tone audiometry was performed preoperatively at 500, 1000, 2000, and 4000 Hz, and the air-bone gap (ABG) for each frequency was determined. The patients underwent endoscopic cartilage tympanoplasty utilizing the tragal cartilage with its perichondrium after separation. Graft uptake rate and hearing gain by ABG reduction were assessed 3 months after the procedure. Data analysis was carried out with SPSS version 22. Results: We studied 71 females and 64 males. Preoperative ABG at 500, 1000, 2000, and 4000 Hz were 25 ± 4, 23.5 ± 4, 23.6 ± 4, and 23.9 ± 3, respectively. Postoperative hearing gains for the above frequencies were 16.4 ± 3, 16.1 ± 4, 14.7 ± 4, and 15.6 ± 4, respectively. Graft uptake rate was 91.8% with complete closure of perforation and only 8.2% with residual tiny perforation that looked like a slit. Conclusion: Endoscopic cartilage tympanoplasty is an effective method for the improvement of hearing and the repair of challenging anteriorly extended tympanic membrane perforation.
