Cartilage myringoplasty for Tympanic membrane perforations: our experience in tertiary care hospital in Kathmandu, Nepal

Objective To study of outcome in myringoplasty using tragal cartilage.

Material and methods It’s a retrospective chart review of all the cases operated for tympanic membrane perforation using tragal cartilage done in Nepal Police hospital, Maharajgung, Kathmandu,Nepal from 2019 June to 2022 July. A detailed history, clinical examination, diagnostic nasal endoscopy, otoendoscopy were done for all patients preoperatively and postoperatively at three weeks, three months and six months. Audiological evaluation was done at six months postsurgery. Cartilage-perichondrium composite graft from tragal was used for the repair of tympanic membrane in all the cases. Data was entered into MS Excel for verification and transferred into Statistical Package for the Social Sciences (SPSS). . Frequency, percentage, means, standard deviation calculated for descriptive data.

Results Total of 300 patients underwent the surgery. All the patients underwent under local anaesthesia. Tragal cartilage with perichondrium was used in all cases. All the patients underwent type-1 tympanoplasty. Successful graft uptake was seen in 279 cases (93%) by six months. Twenty one patients (7%) had a residual perforation at three months by the end of six months. With respect to hearing, maximum air bone gap closure achieved in our study was 19db in one patient and minimum was 3db. Average air bone gap closure achieved was 10.1db.

Conclusion Cartilage-perichondrium composite graft can be considered a good choice in repair of tympanic membrane perforations.
