摘　　要：目的评估一种优化设计的3D数字外科导板在陈旧性颧弓骨折精准治疗中的应用价值。方法选择2016年6月~2018年6月在四川大学华西口腔医院行手术治疗的陈旧性颧弓骨折患者共27例,随机分为A、B、C三组,每组各9名。A组采用3D打印的数字外科导板引导结合钛板预成形技术治疗颧弓骨折,B组仅应用钛板预成形技术治疗骨折,C组依据术者经验对颧弓骨折进行治疗。将手术疗效的评判标准分为甲、乙、丙三级,比较三组患者的手术效果。结果手术时间:A组<B组<C组(P<0.05);手术疗效:甲等率:A组>B组>C组,乙等率:B组>C组>A组,丙等率:A组<B组<C组(P<0.05)。结论优化设计的数字导板在陈旧性颧弓骨折的治疗中较以往的治疗方法有显著优势,其显著缩短手术时间且精确地将术前设计转化到了现实手术中,达到了精准治疗的临床需求。Objective To evaluate the application of modified digital guide plate in precise treatment of old zygomatic arch fractures. Methods 27 patients with old zygomatic arch fracture were randomly divided into three groups. Group A was treated with preformed titanium plates and modified digital guide plate, Group B with preformed titanium plates only and Group C with surgical treatment based on the experience of surgeon. The criteria for judging the curative effect were divided into three grades: Good, Medium and Bad. The postoperative effects of three groups were compared. Results The operation time of group A was shorter than that of group B, and the operation time of group B was shorter than that of group C(P<0.05). The proportion of good effect of group A was higher than that of group B, and The proportion of good effect of group B was higher than that of group C(P<0.05). The proportion of bad effect of group A was lower than that of group B, and The proportion of bad effect of group B was lower than that of group C(P<0.05). Conclusion The postoperative effect of old zygomatic arch fractures assisted by digital surgery is significantly better than that of the surgery based on the experience of surgeon. The modified digital guide plate has a significant advantage over the traditional surgery in the treatment of old zygomatic arch fractures. It shortens the operation time and accurately converts the preoperative design into the real surgery, which realizing the purpose of precision treatment.
