目的探讨应用穿颊器与下颌磨牙后区微创切口联合治疗下颌角骨折的临床效果。方法将下颌角及下颌角升支骨折患者40例随机分为治疗组和对照组，每组20例。治疗组术前实施微创切口内固定复位联合穿颊器疗法，对照组行常规口外入路手术疗法，比较两组的临床效果、手术参数指标变化、术后并发症情况。结果治疗组的临床效果明显优于对照组（P＜0.05）；治疗组手术时间、术中出血、住院时间等各参数指标变化及术后并发症与对照组比较，差异有统计学意义（P＜0.05）。结论下颌磨牙后区微创切口与穿颊器联合治疗下颌角骨折及下颌角升支骨折，微创度高，术后并发症少，临床效果确切，安全可靠，值得临床推广。

ObjectiveTo study the clinical effect of transbuccal instrument combined with mandibular retromolar area minimally invasive incision in the treatment of mandibularangle fracture.MethodsForty patients with mandibular angle or mandibular angle ramus outermost fracture were randomly divided into treatment group or control group, 20 cases in each group. The treatment group was performed with minimally invasive incision fixation reduction combined with transbuccal instrument therapy, while the control group was given routine extraoral approach operation therapy. Clinical effect, operation parameters change,and postoperative situation were compared between the two groups. ResultsThe cli nical effect of treatment group was better than that of the control group (P＜0.05); and there was a statistical difference between the two groups in operation time, intraoperative bleeding, and hospitalization time variation parameters (P＜0.05).ConclusionTransbuccal instrument therapy combined with mandibular retromolar area minimally invasive incision in the treating of mandibular angle fractures and mandibular ramus fractures is highly microinvasive, with less postoperative complication, assured clinical efficacy, and safety, implying its broad clinical promotion
