Abstract

This study aims to evaluate the post-surgical stability of patients with cleft lip and palate that underwent maxillary advancement surgery. The study was conducted by means of cephalometric analysis of the soft tissues in digital radiographs acquired preoperatively, immediate postoperatively and six months after surgery using Dolphin Imaging 11.5 software. The effective sample consisted of 87 patients, among whom 50 (57.4%) were male and 37 (42.6%) were female. The mean age of the patients was 23.1 years, the minimum age was 17 years, and the maximum age was 37 years. Patients underwent maxillary advancement with cephalometric analysis during the preoperative and postoperative period, which was around six months. The results revealed a significant tendency for relapse in the vertical direction with instability of the occlusal plane. In the postoperative period, counterclockwise movement of the maxillomandibular complex was observed, leading to height reduction of the lower third of the face and increased facial angle. The observed changes were not correlated with the extent of the sagittal advancement.

评估唇腭裂患者术后上颌前移稳定性。

本研究旨在评估唇腭裂患者行上颌前移手术后的术后稳定性。本研究采用Dolphin Imaging 11.5软件对术前、术后即刻及术后6个月获得的数字x线片软组织进行头颅测量分析。有效样本87例，其中男性50例（57.4%），女性37例（42.6%）。患者平均年龄23.1岁，最小年龄17岁，最大年龄37岁。患者在术前和术后6个月左右进行上颌推进和头部测量分析。结果显示，在垂直方向上复发的趋势明显，且咬合面不稳定。术后观察到上颌下颌复合体逆时针运动，导致面部下三分之一高度降低，面部角度增加。观察到的变化与矢状位进展的程度无关。
