Abstract：
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.
摘要：
修复外科医生通常使用游离的前臂皮瓣进行鼻重建，当前额皮瓣不是一种选择时，但是这种皮瓣有缺点。本文介绍了一系列使用股前外侧（ALT）皮瓣进行重建的复杂缺损患者。严重烧伤和癌症切除可能导致多个解剖单元的丢失，包括整个鼻子和附近的结构。对于涉及相邻区域的复杂的总鼻缺损的患者，需要多种材料进行重建。在这一系列患者中，收集嵌合ALT瓣并使其变薄以重建三维鼻腔结构并覆盖相邻区域.软骨和异体材料被用作鼻框架，皮瓣折叠成粘膜衬里。结果很好，轮廓很好，随访期间无并发症及气道阻塞。通过减薄ALT皮瓣，这种皮瓣可以替代需要面部或三维鼻结构的复杂重建。
