The reconstruction of large full-thickness alar defects requires complex surgical procedures that are usually performed in two stages, with concomitant disadvantages in terms of patient trauma, surgical risk, and cost. This study presents a functional folded nasolabial island flap (FNIF) that can be used to repair large-sized full-thickness alar defects in a straightforward manner.
This retrospective study included seven patients who received a FNIF for a full-thickness alar defect between January 2007 and December 2020. The FNIF is different from the conventional nasolabial flap in that it is folded and twisted to achieve nostril reconstruction with a satisfactory three-dimensional mucosal lining in a single stage. The cosmetic and functional results of FNIF were evaluated by both patients and physicians.
The age ranged from 51 to 82 years (mean, 65.6 years). The causes of the defects were squamous cell carcinoma, basal cell carcinoma, and trigeminal trophic syndrome. The nostril lining did not collapse, there was no hypertrophic scarring, and air movement through the nostrils on the flap side was normal. Overall, FNIF produced excellent aesthetic and functional outcomes, with minimal patient discomfort. There were no postoperative complications.
Compared with existing reconstruction methods for large full-thickness alar defects, FNIF can easily achieve aesthetic and functional success in a single-stage procedure. It provides satisfactory results for both the patient and the surgeon.
大面积全层鼻翼缺损的修复需要复杂的外科手术，通常分两期进行，在患者创伤、手术风险和成本方面存在相应弊端。本研究提出一种功能性折叠鼻唇岛状皮瓣（FNIF），可直接用于修复大面积全层鼻翼缺损。
这项回顾性研究纳入了2007年1月至2020年12月期间因全层鼻翼缺损接受FNIF手术的7例患者。FNIF与传统鼻唇瓣不同，它通过折叠和扭转，在一期手术中实现鼻孔重建，形成满意的三维黏膜内衬。由患者和医生共同评估FNIF的美容和功能效果。
患者年龄51至82岁（平均65.6岁）。缺损原因包括鳞状细胞癌、基底细胞癌和三叉神经营养综合征。鼻孔内衬未塌陷，无肥厚性瘢痕形成，皮瓣侧鼻孔通气正常。总体而言，FNIF产生了极佳的美学和功能效果，患者不适极小。无术后并发症。
与现有的大面积全层鼻翼缺损重建方法相比，FNIF可在一期手术中轻松实现美学和功能上的成功。它为患者和外科医生都提供了满意的结果。
