Audiometric Results after Type I Tympanoplasty: Retrospective Study

Abstract

Type I tympanoplasty is a common surgery in otorhinolaryngology. The main objective is to restore the integrity of the tympanic membrane, preventing infections, and improving hearing.This is a retrospective study of all patients who underwent Portmann type I tympanoplasty at the Garcia de Orta hospital in the last 10 years. The types of graft used and the pre- and postoperative audiometric results were recorded and the anatomical and audiometric success rates were analyzed.72 patients were included, with a mean age of 54 years. The study revealed a success rate of 70% in relation to closing the perforation and 60% in relation to closing the air-bone gap. The best graft in terms of closure was the temporal fascia + cartilage, a statistically significant result. In terms of closure of the air-bone gap, it was the temporal fascia, but it was not statistically significant. The anatomical and audiometric results are comparable to those published in the literature.
