Abstract

Arteriovenous malformation (AVM) is a direct communication between an artery and vein without capillary connections and it is mainly found in the intracranial region. However, in an extracranial region, an AVM of the external ear is relatively uncommon. Recently, we experienced a case of an AVM in the external ear. A 20-year-old male patient presented with pulsatile tinnitus over the past 7 months and a reddish and pulsatile mass of the left external ear. We successfully treated the patient for the AVM in the external ear by complete excision after preoperative selective embolization.

摘要

动静脉畸形（AVM）是一种动脉与静脉之间的直接连通，没有毛细血管连接，主要见于颅内区域。然而，在颅外区域，外耳道动静脉畸形相对少见。最近，我们遇到了一例外耳道动静脉畸形病例。一名20岁男性患者在过去7个月中出现搏动性耳鸣，左耳外耳道有一个红色搏动性肿物。我们在术前选择性栓塞后通过完全切除成功治疗了该患者的外耳道动静脉畸形。
