The goal of this study was to evaluate the incidence of postoperative wound infection and timing of mandibular third molar removal in bilateral sagittal split osteotomy (BSSO). This wis a prospective, single-blinded, randomized, split-mouth clinical trial. All patients were divided into two groups: Group I, where pre-operative removal of the third molars were done 6 months prior to BSSO and Group II, where intra-operative removal of contralateral third molars were done for the same patients during the osteotomy. The primary outcome variable studied was postoperative infection rate and the secondary outcome variable was bad split during BSSO. Among the seventy five patients (150 sites), one site in group II developed infection whereas none of the sites in group I developed infection (p = 1.000). No sites had bad split in both the groups. The results from the present study show that there is no difference between the presence or absence of mandibular third molars on post-operative wound infection following bilateral sagittal split osteotomy, and the authors hence suggest removing third molars during BSSO for patient comfort.
本研究的目的是评估双侧矢状劈开截骨术（BSSO）后伤口感染的发生率以及下颌第三磨牙拔除的时机。这是一项前瞻性、单盲、随机、双侧对照的临床试验。所有患者分为两组：第一组，在BSSO术前6个月拔除第三磨牙；第二组，在截骨术中为同一患者拔除对侧第三磨牙。研究的主要结局变量是术后感染率，次要结局变量是BSSO过程中的不良劈开。在75例患者（150个部位）中，第二组有1个部位发生感染，而第一组无部位发生感染（p = 1.000）。两组均无不良劈开部位。本研究结果表明，双侧矢状劈开截骨术后伤口感染与否与下颌第三磨牙的有无无关，因此作者建议为了患者舒适，在BSSO过程中拔除第三磨牙。
