고막성형술의 치료성적

Abstract

A review of the literature reveals that many technique have been developed and employed successfully. We have been carried out new tehnique of myringoplasty in chronic otitis media patients with simple perforated drum. To evaluate the results of tympanic graft technique and to identify factors that could influence the success of tympanoplasties, a retrospective study of 163 patients who had undergone myringoplasty during the years 1990-1995 at the Department of Otolaryngology in Yonsei Medical Center was performed. The myringoplasty was conducted by the following described techniques：1) Grafting the drum with onlay technique on the anterior portion of the annulus. 2) Graft material was inserted into medial side of malleus handle. 3) Tympanomeatal flap was dividing and the drum was covered by the skin of the posterior external auditory canal as taking under one’s wing. Anatomic success rate was 92%. There was no statistically significant correlation between the age, location of perforation, middle ear mucosa status, eustachian tube function and the outcome of the uptake rate. The most decisive factor influencing results appeared to be the surgeon’s technique. When compared between preoperative and postoperative air-bone gap, worsened hearing postoperatively was observed in 3.7%. Postoperative complications were reperforation (8%), draining (3.1%), and hearing loss (3.7%). We conclude that myringoplasty as stated above is a safe procedure and has a high probability of success.
