Bone movement in orthognathic surgery gives rise to changes in the positions of the adjacent soft tissues, with such change varying according to the location, direction, and degree of movement. The behavior of the soft tissues, especially the labial tissues, can be influenced by the type of suture employed. This study sought to characterize alterations induced into the soft tissue, by the effect of different suturing techniques, on the upper lip in patients undergoing surgically assisted maxillary expansion. Twenty-three patients were divided into 2 groups and analyzed, with group 1 receiving conventional suturing and group 2 receiving the simple V-Y suture. The results were determined through cephalometric tracings conducted immediately preoperative and a minimum of 6 months postoperative. From these results, it was possible to detect a tendency toward more posterior positioning of the upper lip with this procedure, which can be compensated by the V-Y suture. Alterations in the vertical position of the soft tissues were not significant.
正颌外科手术中的骨移动会引起相邻软组织位置的变化，这种变化会根据移动的位置、方向和程度而有所不同。软组织的行为，尤其是唇部组织的行为，会受到所采用缝合方式的影响。本研究旨在通过不同缝合技术，描述手术辅助上颌扩弓患者上唇软组织的改变情况。23例患者被分为两组并进行分析，第1组采用传统缝合，第2组采用简单V-Y缝合。结果通过术前即刻及术后至少6个月进行的头影测量描记来确定。从这些结果中，可以检测到该手术使上唇有更向后定位的趋势，而V-Y缝合可以对此进行补偿。软组织垂直位置的改变并不显著。
