Ⅰ．はじめに
　従来，海綿状血管腫（cavernous hemangioma）と称されてきた疾患は，病理学的には血管腫瘍ではなく静脈成分を主体とした低流速の血管形成異常である．これまで本疾患に対してはさまざまな名称が用いられ混乱がみられたが，最近，International Society for the Study of Vascular Anomalies（ISSVA）分類に基づき血管奇形（vascular malformation）の一種として静脈奇形（venous malformation）と診断されるようになってきている^2,6,23)．本稿ではvenous malformation（VM）の名称に統一し，われわれが経験した内視鏡下経鼻手術（endoscopic endonasal surgery：EES）を行った下内側型眼窩静脈奇形（venous malformation of the orbit：VMO）の2症例について，手術方法と工夫について述べる．
