Orthognathic surgeries are considered successful on the basis of postoperative stability, vascularity, and relapse rates. One among them is the multisegment Le Fort I osteotomy, which has often been disregarded due to vascular compromise. The complications associated with such an osteotomy are also primarily due to vascular ischemia. In the past, it was hypothesized that segmentation of the maxilla disrupted vascular supply to the osteotomized segments. However, the case series attempts to analyze the complications associated with a multisegment Le Fort I osteotomy and its incidence. This article documents four such cases that involve a Le Fort I osteotomy along with anterior segmentation. The patients experienced minimal or no postoperative complications. Thus, the case series exhibits that multisegment Le Fort I osteotomies can be successfully carried out without much complications and hence prove to be a safe treatment option in cases of increased advancement, setback, or combination.
正颌手术的成功与否是基于术后稳定性、血运情况和复发率来判断的。其中一种手术是多节段Le Fort I型截骨术，由于血管受损，这种手术常常被忽视。与这种截骨术相关的并发症也主要是由于血管缺血。过去，人们推测上颌骨的分段会破坏截骨段的血液供应。然而，该病例系列试图分析多节段Le Fort I型截骨术相关的并发症及其发生率。本文记录了4例涉及Le Fort I型截骨术及前部截骨的病例。这些患者术后并发症极少或没有并发症。因此，该病例系列表明，多节段Le Fort I型截骨术可以成功实施，且并发症较少，因此在需要增加前徙、后退或联合手术的病例中被证明是一种安全的治疗选择。
