当前额皮瓣不可行时，重建外科医生经常使用游离桡侧前臂皮瓣进行鼻部重建，但这种皮瓣有缺点。本文介绍了一系列患有复杂缺损的患者，他们接受了大腿前外侧 (ALT) 皮瓣重建。严重烧伤和癌症切除可能会导致多个解剖单位的丧失，包括整个鼻子和附近的结构。对于涉及邻近区域的复杂鼻部缺损的患者，需要多种材料进行重建。在这一系列患者中，采集了嵌合 ALT 皮瓣并使其变薄，以重建三维鼻结构并覆盖邻近区域。软骨和异体材料用作鼻框架，皮瓣折叠作为粘膜衬里。结果良好，轮廓良好，随访期间未观察到并发症或气道阻塞。通过使 ALT 皮瓣变薄，该皮瓣可以成为需要面部或三维鼻结构的复杂重建的替代方案。版权所有 © 2024 作者。由爱思唯尔公司出版。保留所有权利。

Reconstructive surgeons often use a free radial forearm flap for nasal reconstruction when a forehead flap is not an option, but this flap has drawbacks. This article presents a series of patients with complex defects who underwent reconstruction with an anterolateral thigh (ALT) flap. Severe burns and cancer resection may lead to the loss of multiple anatomical units, including the entire nose and nearby structures. Multiple materials are required for reconstruction in those with complex total nasal defects involving adjacent areas. In this series of patients, a chimeric ALT flap was harvested and thinned to recreate the three-dimensional nasal structure and cover the adjacent area. Cartilage and alloplastic materials were used as the nasal framework, and the skin flap was folded for the mucosal lining. The results were good with an excellent contour, and no complications or airway obstruction were observed during follow-up. By thinning the ALT flap, this flap can be an alternative for complex reconstructions that require a facial or three-dimensional nasal structure.Copyright © 2024 The Authors.
