目的探讨计算机辅助导航系统(computer-assisted navigation system,CANS)手术与传统手术比较能否提高单侧陈旧性颧骨复合体(zygomatic complex,ZMC)骨折的治疗效果.方法选择24例需手术矫治的单侧陈旧性ZMC骨折患者,采用1:1配对的病例-对照回顾性研究,将患者分为研究组(导航手术组,12例)和对照组(传统手术组,12例).通过术后CT测量、患者术后满意度自评及临床检查,评价CANS的治疗效果.结果术后三维CT测量显示,研究组双侧颧骨突度及宽度差值分别为1.58 mm、1.47 mm,对照组分别为3.58 mm、3.63 mm,两组差异均有统计学意义;术后3个月随访结果显示,所有患者未出现相关并发症,研究组患者均对疗效满意,对照组2例患者要求进一步手术修整颧骨外形.结论 CANS手术可提高单侧陈旧性ZMC骨折的治疗效果.

Objective To investigate whether the surgery resorting to computer-assisted navigation system (CANS) can enhance effects in managing unilateral old zygomatic complex (ZMC) fracture in comparison with conventional surgery.Methods Twenty-four patients with unilateral old ZMC fracture for which surgical correction was wanted were divided into study group (n =12,treated with navigational surgery) and control group (n =12,treated with traditional surgery) in the 1 ∶ 1 matched case-control study.Therapeutic effects of CANS were evaluated by postoperative CT measurement,subjective satisfaction questionnaire and clinical examination.Results According to postoperative three-dimensional CT measurement,the mean projection and width differentials of bilateral zygomatic bones were 1.58 mm and 1.47 mm in study group,3.58 mm and 3.63 mm in control group,with significant differences between groups.No complications occurred within three months of follow-up.Moreover,the patients in study group were all satisfied with the treatment,but two patients in control group desired further surgery to ameliorate zygomatic shape.Conclusion Surgery with application of CANS improves efficacy of treatment for unilateral old ZMC fracture.
