Bilateral sagittal split osteotomy (BSSO) is a surgical technique to correct hypoplasia, hyperplasia or asymmetry of the mandible. The risk of complications associated with BSSO with splitter and separators, the so-called splitter-separator technique, and the predictability of this technique were analysed. The average incidence of complications associated with classic BSSO techniques was determined by a review of the literature. With classic techniques, a bad split occurred in 2.3% of the operated sides, removal of osteosynthesis material on account of complaints in 11.2% of patients, and permanent neurosensory disturbances in the area of the mental nerve in 33.9% of patients. The incidence of complications for BSSO with splitter and separators is a bad split in 2.0% of the operated sides, necessary removal of osteosynthesis material in 5.6% of patients, and permanent neurosensory disturbances of the lower lip in 9.9% of patients. Removal of the third molars during BSSO may result in an increased chance of bad split but does not increase the risk of other complications. In conclusion, BSSO with splitter and separators is a reliable technique, with a remarkably low incidence of permanent neurosensory disturbances of the lower lip.
双侧矢状劈开截骨术（BSSO）是一种用于矫正下颌骨发育不全、增生或不对称的外科技术。分析了使用劈裂器和分离器的BSSO（即所谓的劈裂器-分离器技术）相关并发症的风险以及该技术的可预测性。通过文献回顾确定了经典BSSO技术相关并发症的平均发生率。采用经典技术时，手术侧出现不良劈开的比例为2.3%，11.2%的患者因出现不适而取出内固定材料，33.9%的患者颏神经区域出现永久性神经感觉障碍。使用劈裂器和分离器的BSSO并发症发生率为：手术侧出现不良劈开的比例为2.0%，5.6%的患者需要取出内固定材料，9.9%的患者下唇出现永久性神经感觉障碍。BSSO期间拔除第三磨牙可能会增加出现不良劈开的几率，但不会增加其他并发症的风险。总之，使用劈裂器和分离器的BSSO是一种可靠的技术，下唇永久性神经感觉障碍的发生率极低。
