This retrospective study was performed to report the peri- and postoperative complications encountered by patients who underwent Le Fort I osteotomy, as well as predictor variables affecting the risk of complications. Patients who underwent only Le Fort I osteotomy were included in the study. Information on peri- and postoperative complications were collected from the patient data records. The effects of certain predictor variables on complication rates were also studied. Twenty-four per cent of the patients suffered from complications, six (6.1%) of whom were reoperated. Most of the complications were minor and transient. Compared with one-piece osteotomy, segmental osteotomy was a significant risk factor predisposing patients to postoperative complications (p = 0.04619). Additionally, the use of patient-specific implants seemed to increase the risk of both perioperative and postoperative complications (p = 0.0248). Currently, the conventional plate fixation method is the primary method in Le Fort I osteotomies. Careful patient selection, surgical planning, and selection of surgical technique seem to be the most important factors in reducing the complication risk. Special attention should be paid with segmental osteotomy surgery.
本回顾性研究旨在报告接受 Le Fort I 骨切开术患者的围手术期并发症，以及影响并发症风险的预测变量。研究纳入仅接受 Le Fort I 骨切开术的患者。从患者数据记录中收集围手术期并发症信息。还研究了某些预测变量对并发症发生率的影响。24%的患者出现并发症，其中 6 人（6.1%）需要再次手术。大多数并发症是轻微和短暂的。与单块骨切开术相比，节段性骨切开术是导致术后并发症的显著危险因素（p=0.04619）。此外，使用个体化植入物似乎增加了围手术期和术后并发症的风险（p=0.0248）。目前，传统的钢板固定方法是 Le Fort I 骨切开术的主要方法。仔细的患者选择、手术计划和手术技术的选择似乎是降低并发症风险的最重要因素。应特别注意节段性骨切开术。
