摘要

引言 嘴唇对面部吸引力和正颌外科手术的决定起着至关重要的作用。目的 评估因上颌骨前移和/或阻塞而接受 Le Fort I 截骨术后上唇的变化。方法 在本回顾性非随机临床试验中,我们对 3 组接受 Le Fort I 上颌骨截骨术的患者进行了评估。第一组(35 人)接受上颌前移术,第二组(14 人)接受上颌阻滞术,第三组(11 人)同时接受上颌前移术和上颌阻滞术。术前测量了所有患者的嘴唇厚度,并将每组患者分为薄唇(< 12 毫米)和厚唇(> 12 毫米)两组。使用 Dolphin 软件对患者的初次(正颌手术前)和最终(正畸托槽移除后)侧向头影进行分析。在 IBM SPSS Statistics for Windows 软件中使用配对 t 检验和线性回归进行比较。结果 上颌骨前移术后,上唇长度平均增加了 1 毫米(p = 0.012),而上颌骨阻塞术后,上唇长度平均减少了 0.43 毫米(p = 0.24)。在上颌前突组中,切牙角度的变化可以预测切迹的显示 ( p = 0.03)。在上颌阻塞组,垂直维度的骨骼变化可预测上唇长度的变化 ( p = 0.033)。结论 用于上颌前突的 Le Fort I 截骨术可显著增加上唇长度。术前对嘴唇厚度的评估有助于预测术后效果。改变切牙的角度可以预测切口的显示效果。在上颌阻塞术中,垂直维度的骨骼变化可以预测上唇长度的变化。

Effects of Maxillary Movements on Lips Following Orthognathic Surgery: A Retrospective Non-Randomized Clinical Trial.

Introduction  Lips play a fundamental role in facial attractiveness and in decisions pertaining to orthognathic surgery. Objective  To assess the upper lip changes following Le Fort I osteotomy for maxillary advancement and/or impaction. Methods  In the present retrospective non-randomized clinical trial, we evaluated 3 groups of patients who underwent Le Fort I osteotomy of the maxilla. Group 1 (n = 35) underwent maxillary advancement, group 2 (n = 14), maxillary impaction, and group 3 (n = 11) was submitted to both maxillary advancement and impaction. The lip thickness of all patients was measured preoperatively, and the participants in each group were categorized into two subgroups: thin (< 12 mm) and thick (> 12 mm) lip. The primary (before orthognathic surgery) and final (after orthodontic bracket removal) lateral cephalograms of the patients were analyzed using the Dolphin software. Comparisons were made using the paired t -test and linear regression in the IBM SPSS Statistics for Windows software. Results  The length of the upper lip increased by 1 mm ( p  = 0.012) on average following maxillary advancement, and it decreased by 0.43 mm ( p  = 0.24) on average following maxillary impaction. In the maxillary advancement group, the change in angulation of the incisors predicted the incisal display ( p  = 0.03). In the maxillary impaction group, skeletal changes in the vertical dimension predicted changes in upper lip length ( p  = 0.033). Conclusions  Le Fort I osteotomy for maxillary advancement significantly increases the length of the upper lip. The assessment of lip thickness prior to surgery can help predict the postoperative results. Changing the angulation of the incisors can predict the incisal display. In maxillary impaction, skeletal changes in the vertical dimension can predict the changes in the length of the upper lip.
