Tympanoplasty in adults at the Complejo Asistencial Dr. Sótero del Rio (CASR): Review of 5 years experience

Abstract

Introduction: In the third year of the residency of otolaryngology in the Pontificia Universidad Católica de Chile the residents forms part of the “ear committee” of the Hospital Clínico UC and the Complejo Asistencial Dr Sotero del Rio (CASR), is that why we want to review the timpanoplasty results with a follow up of 5 years. Aim: The aim of this study is identify and show the epidemiologic data of the patients who was operated of timpanoplasty in the CASR, also review the different surgical techniques and the anatomic and auditive results. Material and method: A retrospective, descriptive study was made. We review 101 records of all patients older than 15 years old, who presented chronic otitis media and underwent tympanoplasty, between January 200 and December 2004. Results: Anatomical success in 79% of all cases. 62% of all cases were better than 10 dB from base hearing, and 30% keep the same level of hearing, which determines 92% of all the patients with a good hearing outcome. Conclusions: These results correspond to the performance of tympanoplasty practiced mostly by residents of 3rd year and general ENT with different levels of training in otologic surgery. This may explain the slight decrease in the anatomic success compared with national series.
