Abstract：
The lip-splitting approach enables excellent access to all areas of the mouth and pharynx to remove tumors; however, traditional lower lip-splitting incisions produce an unsatisfactory scar. To achieve better functional and aesthetic results, we used a Z-shaped incision and compared the functional and aesthetic outcomes of the straight and Z-shaped incisions. Sixty patients who fulfilled the inclusion criteria were randomly divided into two groups and underwent lip-splitting between March 2021 and September 2023. Eventually, 77 patients were reviewed within 6 months and evaluated using the lip function assessment scale, patient and observer scar assessment scale, naïve observer scar assessment scale, and a clinical examination. The Z-shaped incision group performed better in terms of the lip pout movement at 3 months and in the subjective overall opinion, color, irregularity, and pigmentation at 6 months. The Z-shaped incision group had a lower incidence of notched vermilion. In conclusion, Z-shaped lower lip-splitting incisions have better functional and aesthetic outcomes than traditional straight incisions.Trial registration: Public title: Difference between the effect of Z-shaped and vertical incisions of labiobuccal flap on the recovery of lower lip scars.

摘要：
唇裂方法可以很好地进入口腔和咽部的所有区域，以切除肿瘤；然而，传统的下唇劈开切口会产生不令人满意的疤痕。为了获得更好的功能和美学效果，我们使用了Z形切口,比较了直切口和Z形切口的功能和美学效果.将符合纳入标准的60例患者随机分为两组，并在2021年3月至2023年9月之间进行了唇裂。最终,77例患者在6个月内进行复查，并使用唇功能评估量表进行评估，患者和观察者疤痕评估量表，幼稚观察者疤痕评估量表，和临床检查。Z形切口组在3个月时的唇舌运动和主观总体意见方面表现较好,颜色,不规则，和6个月时的色素沉着。Z形切口组有较低的缺口朱红发生率。总之,与传统的直切口相比，Z形下唇分裂切口具有更好的功能和美学效果。试用注册：公开标题：唇口皮瓣Z形和垂直切口对下唇疤痕恢复的影响之间的差异。注册日期：2021年03月09日。注册号:ChiCTR2100044084.注册表URL：http://www。chictr.org.cn.
