Abstract
in English, Portuguese

Introduction: Transcanal myringoplasty has the advantages of demanding lower operative time and minimal external incisions. It can be performed using the microscopic or endoscopic approach. In the last decade, the use of endoscopes in ear surgery has increased significantly. This technique may allow "around the corner" visualization of small recesses, through narrow spaces, without the aid of canalplasty in unfavorable ear canals.

Objective: To describe a case series of transcanal endoscopic myringoplasty performed in a university service. The characteristics, advantages, and disadvantages of this technique are also discussed.

Methods: A case series study, based on the chart review of patients submitted to transcanal endoscopic myringoplasty in the period from January of 2012 to October of 2014.

Results: Data from 22 patients were analyzed. Tympanic perforation closure three months after surgery was observed in 86.4% of all patients. There was statistically significant improvement in pure tone average thresholds after surgery (p<0.001).

Conclusion: Transcanal endoscopic myringoplasty is a feasible, safe, and effective procedure; it can be an alternative to microscopic surgery.

Introdução: A miringoplastia realizada por via transcanal possui como vantagens a maior rapidez do procedimento e menor incisão externa, podendo ser realizada com auxílio de microscópio ou endoscópio. Na última década tem sido observado um aumento do uso de endoscópios na cirurgia otológica. Essa técnica pode permitir melhor visibilização de espaços encobertos e estreitos, sem necessidade canaloplastia em meatos desfavoráveis.

Objetivo: Descrever uma série de casos de miringoplastia endoscópica transcanal, em um serviço universitário, discutindo suas particularidades, vantagens e desvantagens.

Método: Estudo de série de casos, baseado na revisão de prontuários dos pacientes submetidos a miringoplastia com uso exclusivo de endoscópio rígido, no período de Janeiro de 2012 a Outubro de 2014.

Resultados: Foram analisados os dados de 22 pacientes. Na otoscopia pós-operatória, foi observado fechamento da perfuração timpânica em 86,4% dos pacientes, após 3 meses da intervenção. Para a amostra estudada, foi observada melhora funcional estatisticamente significante da média dos limiares tonais (PTA) após a cirurgia (p < 0,001).

Conclusão: A miringoplastia endoscópica transcanal é um procedimento seguro, factível e efetivo, podendo ser realizado como alternativa à cirurgia microscópica.
