This study aims to analyse the relationship between the incidence of bad splits and the surgical tools adopteded to perform bilateral sagittal split ramus osteotomy (BSSRO).BSSROs performed by the same experienced surgeon period were reviewed, retrospectively. The patients were divided into three groups according to the surgical instrument used to perform the osteotomy: a Lindemann burr, reciprocating saw or piezosurgery. Among the 1120 BSSROs performed, 5 bad fractures were detected during the observation period: 3 among patients operated with the Lindemann burr (0.8%) and 2 among those operated with a reciprocating saw (0.5%). There was no significant correlation between the bad split rate and age and gender of the patients, the type of malocclusion or the type of instrument used to perform the osteotomy. Within the limitations of the study it seems that the the choice of the osteotomy tool for BSSRO does not influence the rate of bad fractures and, therefore, the selection of the osteotmy tool should be left to the discretion of the surgeon.
本研究旨在分析 Bad splits 发生率与双侧矢状劈开截骨术（Bilateral sagittal split ramus osteotomy，BSSRO）中使用的手术工具之间的关系。回顾性分析了由同一位经验丰富的外科医生进行的 BSSRO。根据用于进行截骨术的手术器械将患者分为三组：Lindemann 磨钻、往复锯或超声骨刀。在观察期间，1120 例 BSSRO 中发现了 5 例 Bad fractures：3 例使用 Lindemann 磨钻（0.8%），2 例使用往复锯（0.5%）。Bad splits 发生率与患者的年龄和性别、错颌类型或用于进行截骨术的器械类型之间无显著相关性。在研究的限制范围内，似乎 BSSRO 中使用的截骨工具的选择并不影响 Bad fractures 的发生率，因此，截骨工具的选择应留给外科医生自行决定。
