はじめに

　眉は顔面の重要な構成要素であり，熱傷などの外傷後に生じた眉の欠損は整容性を大きく損なう。眉を再建する際には，欠損の部位や範囲および周囲組織の状態，さらに残存する眉の形状などを考慮して手術方法を選択する必要がある。

　今回，眉の外側2/3の欠損に対して，対側の眼輪筋を茎とした眉部の島状皮弁による再建（以下，本法）を行い，ほぼ満足する結果を得たので報告する。

　Reconstruction of scarring eyebrow defects is a challenging task for plastic surgeons, as the eyebrow is a very important cosmetic landmark of the face. A variety of methods are used for eyebrow reconstruction: free hair follicle transplantation, scalp composite graft, local flap transposition, and hair-bearing island scalp flap have been widely reported in the past. These are applied according to the size and position of the eyebrow defect. For partial defects, the best option is the use of local flaps from the remaining ipsilateral eyebrow, which have characteristics that are highly similar to those of the recipient site. Herein, we present a case in which an orbicularis oculi muscle pedicled flap from the contralateral eyebrow was used as a donor site with good results.
