Nasolabial sulcus rejuvenation is steadily gaining popularity among Asians. Though many treatment options using synthetic grafts and autografts have been introduced, none of them has yet been accepted as an ideal technique. This study describes the operative procedure and evidence-based clinical outcomes of paranasal augmentation using dermal grafts.
From March 2015 to August 2019, 56 patients underwent paranasal augmentation. The dermal graft, harvested from the buttock, was folded into 4 to 6 layers and inserted into the supraperiosteal pocket through a gingivobuccal incision. Ultrasonographic evaluation was performed at postoperative months 1, 6, 12, and 18 to appraise the change in the thickness of the graft.
No major complications, including foreign body sensation and graft extrusion, occurred. The average dermal thickness was 10.31 mm at postoperative month 1 and 6.30 mm, 5.21 mm, and 5.17 mm at postoperative months 6, 12 and 18, respectively. The average absorption rates were 38.72%, 49.36%, and 49.92% at postoperative months 6, 12, and 18, respectively.
Paranasal augmentation using a folded dermal graft serves as a useful method to rejuvenate the midface with durable and aesthetically satisfactory outcomes. By virtue of biocompatibility, complications occurred rarely compared with the artificial implants.

鼻唇沟年轻化在亚洲人中越来越受欢迎。虽然已经引入了许多使用合成移植物和自体移植物的治疗选择，但没有一种被认为是理想的技术。本研究描述了使用真皮移植物进行鼻旁隆凸的手术过程和基于证据的临床结果。
从 2015 年 3 月至 2019 年 8 月，56 例患者接受了鼻旁隆凸术。真皮移植物从臀部采集，折叠成 4 到 6 层，通过牙龈颊切口插入骨膜下袋。术后 1、6、12 和 18 个月进行超声评估，以评估移植物厚度的变化。
无重大并发症，包括异物感和移植物挤出，发生。术后 1 个月和 6 个月的平均真皮厚度分别为 10.31mm 和 6.30mm、5.21mm 和 5.17mm。术后 6、12 和 18 个月的平均吸收率分别为 38.72%、49.36%和 49.92%。
使用折叠真皮移植物进行鼻旁隆凸是一种有用的方法，可以使中面部年轻化，效果持久且美观。由于具有生物相容性，与人工植入物相比，并发症很少发生。
