The aim of this retrospective study was to evaluate the relationships between upper jaw movements and nasal soft-tissue changes in patients who have undergone subspinal Le Fort I osteotomy combined with alar cinch suture. Single and multivariate linear regression analyses were used to examine the relationships between greatest inter-alar width (GAW) and maxillary advancement, maxillary impaction, and rotational movements. The database of our referral hospital was searched for patients who had undergone upper jaw surgery with a subspinal LFI osteotomy to correct dentoskeletal deformities between April 2012 and June 2016. Thirty-eight of the patients (15 men and 23 women) who were identified were eligible for inclusion. The average change in inter-alar width (ΔGAW) was +1.7 ± 1.2 mm. GAW increased by 0.3 mm (p < 0.0001) for each millimetre of maxillary advancement, and increased by 0.5 mm (p < 0.0001) for each millimetre of maxillary impaction. GAW increased by 0.2 mm for each degree of counterclockwise rotation of the occlusal plane (p < 0.0001). An analysis of our data compared with the current literature confirmed that subspinal Le Fort I combined with alar cinch suture reduced alar base widening.
本回顾性研究旨在评估接受经皮下 Le Fort I 截骨术联合鼻翼紧缩缝线固定术的患者上颌骨运动与鼻软组织变化之间的关系。采用单变量和多变量线性回归分析，检验最大鼻翼间宽度（GAW）与上颌骨前徙、上颌骨压低和旋转运动之间的关系。检索了 2012 年 4 月至 2016 年 6 月期间因牙颌面畸形行上颌骨手术的患者数据库，这些患者接受经皮下 Le Fort I 截骨术矫正。符合纳入标准的患者有 38 例（男 15 例，女 23 例）。鼻翼间宽度的平均变化（ΔGAW）为+1.7±1.2mm。上颌骨每前徙 1mm，鼻翼间宽度增加 0.3mm（p<0.0001），上颌骨每压低 1mm，鼻翼间宽度增加 0.5mm（p<0.0001）。咬合平面逆时针每旋转 1°，鼻翼间宽度增加 0.2mm（p<0.0001）。与目前的文献相比，我们的数据分析证实经皮下 Le Fort I 截骨术联合鼻翼紧缩缝线固定术可减少鼻翼基部增宽。
