To evaluate the role of creating an alar-based advancement flap in narrowing the nasal base and correcting excessive alar flare.
Case series with chart review.
This is a retrospective record review study.
The study included 35 cases presenting with a wide nasal base and excessive alar flaring. The surgical procedure combined the alar base reduction with alar flare excision by creating a single laterally based alar flap. Any caudal septal deformities and any nasal tip modification procedures were corrected before the nasal base narrowing. The mean follow-up period was 23 months.
The mean alar flap narrowing was 6.3 mm, whereas the mean width of sill narrowing was 2.9 mm. This single laterally based advancement alar flap resulted in a more conservative external resection, thus avoiding alar wedge overresection or blunting of the alar-facial crease. No cases of postoperative bleeding, infection, or keloid were encountered, and the external alar wedge excision healed with no apparent scar that was hidden in the depth of the alar-facial crease. The risk of notching of the alar rim at the sill incision is reduced by adopting a 2-layer closure of the vestibular floor.
The alar base advancement flap is an effective technique in narrowing both the nasal base and excessive alar flare. It adopts a single skin excision to correct the 2 deformities while commonly feared complications were avoided.
评估在鼻翼基部创建推进皮瓣在缩小鼻基底和矫正过度鼻翼外展方面的作用。
病例系列和图表回顾。
这是一项回顾性记录研究。
该研究包括 35 例鼻翼基部宽大和鼻翼外展过度的病例。手术过程通过创建一个单侧鼻翼基部皮瓣，将鼻翼基部缩小与鼻翼外展切除相结合。在缩小鼻基底之前，先矫正任何鼻中隔尾部畸形和任何鼻尖整形术。平均随访时间为 23 个月。
鼻翼皮瓣平均缩小 6.3mm，而鼻翼基部平均缩窄 2.9mm。这种单侧推进鼻翼皮瓣导致更保守的外部切除，从而避免过度切除鼻翼楔形或使鼻翼-面部折痕变钝。没有术后出血、感染或瘢痕疙瘩的病例，外侧鼻翼楔形切除的愈合没有明显的瘢痕，隐藏在鼻翼-面部折痕的深处。采用前庭底部 2 层闭合，可以降低鼻翼基部切口处鼻翼边缘凹陷的风险。
鼻翼基部推进皮瓣是缩小鼻基底和矫正过度鼻翼外展的有效技术。它采用单次皮肤切除来矫正这两种畸形，同时避免了常见的并发症。
