Half Disc Cartilage Tympanoplasty: A Newer Technique Versus Temporalis Fascia Tympanoplasty-Retrospective Analysis.

Abstract

Tympanoplasty is a surgical procedure performed for the closure of tympanic membrane perforation. The present study was conducted to compare the outcomes of a newer technique of cartilage tympanoplasty which the author has named as half disc cartilage tympanoplasty and temporalis fascia tympanoplasty in the following areas-the improvement in hearing, frequency specific improvement in hearing, graft uptake rate. Retrospective study was conducted in the Department of Otorhinolaryngology Rajagiri Hospital from February 2018 to February 2020. 40 patients with moderate central, subtotal and anterior perforation were included in the study. 20 patients (group A) underwent tympanoplasty with temporalis fascia graft and 20 patients (group B) underwent tympanoplasty with temporalis fascia and cymba concha with perichondrium as the support in the anterior half. Both groups were compared for the improvement in hearing and frequency specific improvement in hearing. Follow up period for the study was 6months. Chi square and t tests were used to assess association and as tests of significance. In our present study hearing improvement following half disc cartilage tympanoplasty was better than temporalis fascia tympanoplasty. In post half disc cartilage tympanoplasty and post temporalis fascia tympanoplasty hearing gain was maximum in low frequencies. Half disc cartilage tympanoplasty is superior to temporalis fascia tympanoplasty in terms of hearing gain. Low frequency hearing shows significant improvement following tympanoplasty.
