对20例患者进行前瞻性研究，以评估上颌前上位Le Fort i型一体式截骨术后鼻内解剖和功能的变化。术前及术后3个月进行鼻部检查、前鼻测量及听鼻测量。测量腭间宽度并使用头颅造影评估上颌运动。鼻镜检查发现3个鼻中隔穿孔（15%）。术后鼻甲扩大较少见。瓣间宽度显著增加。这些发现与术后3个月听鼻测量显示的鼻峡横断面直径显著增加有关。前鼻压测量法测量的平均总鼻气流没有变化，表明在嵌塞不高于5mm的情况下，尽管鼻内尺寸减小，但阻力没有增加。
Twenty patients were studied prospectively to assess intranasal anatomical changes and functional changes resulting from a one-piece Le Fort I-osteotomy with anterior and superior positioning of the maxilla. Presurgical and 3 months postsurgical rhinological inspection, anterior rhinomanometry and acoustic rhinometry were performed. Interalar width was measured and cephalograms were used to assess maxillary movement. Rhinoscopically, three septal perforations (15%) were noticed. Turbinate enlargement was less common postoperatively. Interalar width increased significantly. These findings correlate with a significant increase in cross-sectional diameter at the Isthmus nasi revealed by acoustic rhinometry 3 months postoperatively. The mean total nasal airflow measured by anterior rhinomanometry was unchanged indicating no increase in resistance despite decreased intranasal dimensions in cases where the impaction is not higher than 5 mm.
