The post-operative effects of maxillary le Fort I osteotomies on tooth sensibility and recovery of maxillary sinus integrity has been studied in thirty patients. The results show that tooth sensibility is lost in over 90% of the teeth post-operatively but gradually returns by 18 months in almost all of the teeth. Radiographic examination of the maxillary sinus post-operatively shows total or almost total radiopacity in all patients whereas later controls at 2 months and 6 months show normalisation of the bony and soft tissue structures in over 55% of the patients. At 6 months some of the patients (30%) show latent mucosal borderline swelling either bilateral or unilateral. A certain remodelling of the maxillary sinus was seen in all patients.
对30例患者进行了上颌Le Fort I截骨术对牙齿感觉及上颌窦完整性恢复的术后效果研究。结果显示，术后超过90%的牙齿会失去感觉，但几乎所有牙齿在18个月时感觉会逐渐恢复。术后对上颌窦的影像学检查显示，所有患者的上颌窦均呈现完全或几乎完全不透光，而在2个月和6个月时的后续检查显示，超过55%的患者的骨和软组织结构恢复正常。在6个月时，部分患者（30%）出现双侧或单侧潜在的黏膜边缘肿胀。所有患者均可见上颌窦有一定程度的重塑。
