混合型先天性耳垂裂に対して耳前部からの島状皮弁を用いた耳垂形成を行った1例

Congenital Triple-Lobe-Type Cleft Earlobe Repair Using a Preauricular Flap

はじめに

　先天性耳垂裂は比較的頻度の低い先天性耳介変形である。変形は多様であり，分類や治療方法に関しては諸家の報告 1）～7）があるものの，確立されていない。

　今回われわれは混合型先天性耳垂裂 3）の症例を経験した。組織量の不足を考慮し，耳前部からの島状皮弁を用いて耳垂形成を行い，良好な結果が得られたため報告する。

　Congenital triple-lobe-type cleft earlobe is rare. The clinical presentation of this disorder varies across patients, and an optimal treatment for triple-lobe-type cleft earlobe has not been established. Since a congenital cleft earlobe is associated with some amount of tissue loss, the reconstruction of a smooth earlobe occasionally requires tissue transfer.

　We present the case of a 1-year-old male infant with a triple-lobe-type congenital cleft earlobe, and we describe our surgical procedure that uses a preauricular flap. The patientʼs family was satisfied with the surgical outcome (earlobe shape) at 6 months postoperatively.
