The purpose of this retrospective study was to evaluate the influence of subspinal Le Fort 1 corticotomy (SLF1C) on nasal morphology in patients treated with surgically assisted rapid palatal expansion (SARPE) using three-dimensional (3D) stereophotogrammetry images. A total of 64 patients were enrolled in the study and divided into two groups according to the surgical approach that was used: in group 1 (n = 32) SARPE was performed using a conventional Le Fort 1 corticotomy (CLF1C), and in group 2 (n = 32) SARPE was performed using a subspinal Le Fort 1 corticotomy (SLF1C). Measurements of alar and columellar width, and nasolabial angle were taken on 3D stereophotogrammetry images before and after SARPE using Vectra 3D camera system. Both surgical groups showed a statistically significant increase in alar and columellar width, and nasolabial angle postoperatively (p<0.05). SLF1C resulted in significantly smaller changes of the columellar base postoperatively (p=0.0456). The data suggests that SARPE with an osteotomy of the anterior nasal spine as an additional step to the conventional Le Fort 1 corticotomy results in a smaller increase of the columellar base.
本回顾性研究旨在通过三维（3D）体视摄影图像评估在接受手术辅助快速腭扩张（SARPE）治疗的患者中，经后路 Le Fort 1 骨切开术（SLF1C）对鼻形态的影响。共有 64 名患者入组本研究，并根据所采用的手术方法分为两组：第 1 组（n = 32）采用传统 Le Fort 1 骨切开术（CLF1C）进行 SARPE，第 2 组（n = 32）采用后路 Le Fort 1 骨切开术（SLF1C）进行 SARPE。使用 Vectra 3D 摄像系统在 SARPE 前后对 3D 体视摄影图像进行鼻翼和鼻中隔宽度以及鼻唇角的测量。两组手术组术后鼻翼和鼻中隔宽度以及鼻唇角均有统计学显著增加（p<0.05）。后路 Le Fort 1 骨切开术术后鼻中隔基部的变化明显较小（p=0.0456）。数据表明，在前鼻棘切开术作为传统 Le Fort 1 骨切开术的附加步骤的 SARPE 会导致鼻中隔基部的增加较小。
