広範な膿瘍を形成した先天性耳瘻孔2例—局所皮弁を用いた皮膚形成術

Two Cases of Congenital Auricular Sinus with Large Abscess

I．緒言

　先天性耳瘻孔は日常診療で高頻度にみられる先天奇形の一つであるが，しばしば感染，化膿を繰り返し時にその治療に難渋することもある。また正しい治療の行われていない例もしぼしば見受けられる。今回われわれは度重なる炎症のため広範な膿瘍を形成し陳旧化した大きな皮膚欠損を生じた先天性耳瘻孔2例に対し，局所皮弁を用いた皮膚形成術を施行し良好な結果を得たので，その手術法ならびに先天性耳瘻孔の治療上の問題点につき文献的考察を加えて報告する。

Two cases of congenital auricular sinus with large abscess were presented. The first was a recurrent case in a 12-year-old girl. The other was a case of severe infection in a 6-year-old girl. These cases were treated surgically, but the re-sulting skin defects were so large that primary closure was difficult. The skin defects were there-fore covered with a local skin flap. The author described the detailed technique of these operations.
