In orthognatic surgery of the mandibular ramus, intra-operative complications as a lesion of the inferior alveolar nerve, fractures of the osteotomised segments, incomplete sectioning, malpositioning of segments and haemorrhage may occur. In this report, intra-operative complications in 124 sagittal split osteotomies and 34 vertical ramus osteotomies, carried out in 80 patients, are described. The incidence of intra-operative complications in the sagittal split osteotomies was 25.8%. The complication occurring most frequently was incomplete sectioning (11.2%). This may be avoided by using the modified sagittal split technique. The incidence of complications in the vertical ramus osteotomies was 11.8%.
在下颌升支正颌外科手术中，可能会出现术中并发症，如下牙槽神经损伤、截骨段骨折、截骨不完全、骨段错位和出血。在本报告中，描述了对80例患者实施的124例矢状劈开截骨术和34例升支垂直截骨术中的术中并发症。矢状劈开截骨术中术中并发症的发生率为25.8%。最常出现的并发症是截骨不完全（11.2%）。采用改良矢状劈开技术可避免这种情况。升支垂直截骨术中并发症的发生率为11.8%。
