Resumo

OBJECTIVE: To review the vascular principles of the Le Fort I osteotomy together with a retrospective analysis of the following factors in 16 cases: ligature of the descending palatine arteries, bone segmentations and the types of surgical movements. RESULTS AND DISCUSSION: Mild complications occurred in two patients who had osteotomies in two places. Both had ligature of the palatine descending arteries and superior repositioning with impaction of the posterior maxilla greater than 4 mm. CONCLUSION: According to the literature and the obtained results, the Le Fort I osteotomy without segmentation presents as a very safe procedure for the correction of maxillary deformities. The ligature of the descending palatine artery does not seem to directly affect the occurrence of ischemic sequelae, except when associated with segmentations and major surgical movements.
