传统上，鼻中隔由于其独特的轮廓、邻近软组织的缺乏和脆弱的血管性而难以重建。当地区或区域组织不可用时，微型手术移植可以提供一种重建的方式。在这个回顾性研究中，我们报告了微型手术重建鼻中隔的经验。本研究共纳入了17名患者，分为两组：（第一组）单纯鼻中隔缺损和（第二组）鼻中隔和一些邻近软组织的缺损。第一组有10名患者。平均年龄为41.2岁。随访平均10.1年。致鼻中隔缺损的原因包括外伤、鼻重建的并发症和隆鼻手术的并发症。在这七例病例中，使用了第一掌跖动脉皮瓣7次和桡前臂皮瓣5次。两个皮瓣损失被用第二个自由皮瓣挽救。手术修正平均为1.5次。在第二组中，有7名患者。随访平均10.1年。鼻中隔缺损的原因包括可卡因伤害、癌症和隆鼻手术的并发症。手术修正平均为3.3次。在所有病例中都使用了桡前臂皮瓣。本研究无皮瓣损失。这个系列的所有17例都圆满结束。我们的经验表明，微型手术重建鼻中隔提供了一个可靠而美观的方法。这种技术避免了常常伴随使用局部皮瓣的面部毁容和明显瘢痕。此外，版权所有 © 2023 美国整形外科医师协会。

Traditionally, the columella can be difficult to reconstruct due to its unique contours, paucity of adjacent soft tissues, and tenuous vascularity. When local or regional tissues are unavailable, microsurgical transfer can provide a means for reconstruction. In this retrospective review, we report our experience with microsurgical reconstruction of the columella.Seventeen patients were enrolled in this study and divided into two groups: (Group 1) Isolated columella defects, and (Group 2) Defects of the columella and portions of adjacent soft tissues.There were 10 patients in Group 1. Age averaged 41.2 years. Follow-up averaged 10.1 years. Etiology of the columellar defects included trauma, complication of nasal reconstruction and complication of rhinoplasty. The 1 st dorsal metacarpal artery flap was utilized in seven cases, and the radial forearm flap in five. Two flap losses were salvaged with a second free flap. Surgical revisions averaged 1.5. In Group 2, there were 7 patients. Follow up averaged 10.1 years. Etiology of the columella defects included cocaine injury, carcinoma, and complication of rhinoplasty. Surgical revisions averaged 3.3. The radial forearm flap was utilized in all cases.There were no flap losses. All seventeen cases in this series were brought to a successful conclusion.Our experience has shown that microsurgical reconstruction of the columella provides a reliable and aesthetic means for reconstruction. This technique avoids facial disfigurement and visible scarring that often accompany use of local flaps. In addition.Copyright © 2023 by the American Society of Plastic Surgeons.
