目的：探讨改良口内微创切口入路与颌间牵引联合治疗下颌角骨折的临床疗效。方法将下颌角骨折患者60例随机分为治疗组和对照组，每组30例，治疗组实施经改良口内微创切口内固定复位联合术后2周颌间牵引疗法，对照组实施传统口外入路切口复位内固定疗法，比较两组的临床效果、手术参数指标、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、术中出血等参数及术后并发症与对照组比较，差异有统计学意义（ p＜0.05）。结论经改良口内微创切口入路联合颌间牵引治疗下颌角骨折，术后并发症少，满足患者对美观及术后功能恢复的要求，值得临床推广。

Objective To study the clinical effect of mandibular retromolar area minimally invasive incision combined with intermaxillary traction in the treatment of mandibular angle fracture .Methods Sixty patients with mandibular angle fracture were randomly divided into treatment group or control group , 30 cases in each group .The treatment group was performed with minimally invasive incision fixation reduction combined with two weeks intermaxil -lary traction, 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 .Results The clinical 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 parameter and complication (p<0.05).Conclusion Mandibular retromolar area mini-mally invasive incision combined with intermaxillary traction in the treatment of mandibular angle fractures with less postoperative complication , meeting the requirements on the functional recovery and postoperative appearance of the patients, and implying its broad clinical promotion .
