External canal reconstruction of extensive tissue defects, including auricle or ear canal defects, is challenging. We describe the case of a 28-year-old man who underwent staged skin and nasal septum cartilage grafting for ear canal reconstruction after resectioning a giant arteriovenous malformation of the auricle. We performed arteriovenous malformation resection and reconstruction of the significant tissue defect using an anterolateral femoral skin flap. Simultaneously, a Nelaton catheter stent was placed to temporarily form an external auditory canal. Subsequently, split-thickness skin grafting was performed. Following stent removal, severe external auditory canal stenosis developed. Nasal septum cartilage grafting was performed using a stent after dilating the ear canal. Two years after surgery, the ear canal was not stenotic without the stent. Staged treatment with skin and nasal septal cartilage grafting is a simple and practical option for treating patients with total ear defects for whom a skin flap cannot be used.
广泛组织缺损的外耳道重建，包括耳廓或耳道缺损，具有挑战性。我们描述了一名28岁男性的病例，该患者在切除耳廓巨大动静脉畸形后，分阶段进行了皮肤和鼻中隔软骨移植以重建耳道。我们使用股前外侧皮瓣进行了动静脉畸形切除和重大组织缺损的重建。同时，放置了一根内拉通导管支架以临时形成外耳道。随后，进行了中厚皮片移植。在移除支架后，出现了严重的外耳道狭窄。在扩张耳道后使用支架进行了鼻中隔软骨移植。术后两年，在没有支架的情况下耳道无狭窄。对于无法使用皮瓣的全耳缺损患者，分阶段进行皮肤和鼻中隔软骨移植治疗是一种简单实用的选择。
