経外耳道的内視鏡下耳科手術での薄切軟骨併用の小児鼓膜形成inlay法

Transcanal endoscopic ear surgery inlay myringoplasty using thin-sliced cartilage in children

はじめに

　経外耳道的内視鏡下耳科手術（transcanal endoscopic ear surgery：TEES）の有用性は広く知られている。筆者らはTEESと鼓膜形成inlay法の両方の利点を生かし，小児の鼓膜形成を軟骨膜付き薄切軟骨の移植により行った。良好な上皮化が得られ，有用な鼓膜形成法の1つと考えられたので報告する。

　Myringoplasty using thin-sliced cartilage with the perichondrium was performed in children by taking advantage of both transcanal endoscopic ear surgery and the inlay technique of myringoplasty. In general, pediatric patients are susceptible to reperforations. In cases 1 and 2, enlargement of the perforation was observed after elevation of the tympanic membrane epithelial layer and after removal of the calcified portion of the residual membrane, respectively. To ensure a good surgical outcome, transcanal endoscopic ear surgery inlay myringoplasty using thin-sliced cartilage was performed. In this study, good epithelialization was achieved, suggesting the usefulness of this approach.
