摘要
目的评价单侧颧骨陈旧性骨折患者在数字外科技术辅助下行切开复位内固定术后远期软、硬组织的对称性。方法回顾性分析2017年1月至2019年12月北京大学口腔医院因单侧颧骨复合体陈旧性骨折在数字外科技术辅助下行切开复位内固定术的患者的临床资料。将患者术前及术后1年头面部螺旋CT数据导入ProPlan CMF 3.0软件,通过三维重建分别得到软、硬组织的STL模型,在面中部标记10组硬组织标志点及11组软组织标志点,并建立测量坐标系,测量并计算左、右对称标志点的不对称指数(AI),数据以±s表示,同一组标志点术前与术后1年AI比较采用配对t检验,P<0.05为差异有统计学意义。同时,从正常国人颅颌面三维形态数据库中选取研究对象,使用Microsoft Excel 2017软件绘制正常人AI基线数据图,将患者术前和术后1年软、硬组织标志点AI纳入正常人AI基线图,评估患者软、硬组织对称性。结果共纳入30例单侧颧骨复合体陈旧性骨折患者,男17例,女13例,年龄18~55岁,平均25.2岁。术前硬组织AI为4.5±4.1,术后1年硬组织AI为2.0±1.7,各标志点AI较术前明显降低(P<0.01或<0.05);术前软组织AI为4.5±4.0,术后1年软组织AI为2.3±1.9,各标志点AI较术前明显降低(P<0.01或<0.05)。从数据库中纳入正常人50例,男、女各25例,年龄18~57岁,平均23.8岁,硬组织标志点AI为2.1±2.0,软组织标志点AI为2.0±1.9。患者术后1年硬组织标志点AI均位于对称基线值以内,对称性良好;部分软组织标志点AI高于对称基线值,对称性欠佳。结论单侧颧骨复合体陈旧性骨折患者在数字外科技术辅助下行切开复位内固定术后,其面部软、硬组织三维对称性较术前均有明显改善,而软组织对称性较硬组织相对欠佳。
Objective To evaluate the postoperative symmetry of soft and hard tissues in patients with unilateral old zygomatic fractures.Methods A retrospective analysis of patients who underwent computer-assisted open reduction and internal fixation for unilateral old zygomatic complex fractures.The spiral CT data of the patient before and 1 year after operation was imported into ProPlan CMF 3.0 software to segment the skin and bone STL models.Eleven sets of soft tissue landmarks and 10 sets of hard tissue landmarks in the middle of the face were marked,with a coordinated system for measurement established.The asymmetry index(AI)between each mark point was calculated.The data were expressed by Mean±SD.Paired t-test was used to compare whether there was a statistical difference in the AI of each landmark before and after operation.P<0.05 was considered the difference to be statistically significant.At the same time,the study subjects were selected from the Chinese craniomaxillofacial three-dimensional morphological database.Microsoft Excel 2017 software was used to draw the AI baseline data map of common people.The patients’soft and hard tissue landmarks AI(before and 1 year after surgery)were included in the AI baseline map of common people,and the patient’s soft and hard tissue symmetry was evaluated.Results A total of 30 patients were included in the study,including 17 males and 13 females,age range from 18 to 55 years old,with an average age of 25.2 years.The preoperative hard tissue AI was 4.5±4.1,and the hard tissue AI was 2.0±1.7 one year after surgery,and the difference in the AI of each hard tissue landmark before and 1 year after operation was statistically significant(P<0.01 or<0.05).The preoperative soft tissue AI was 4.5±4.0,and the soft tissue AI was 2.3±1.9 one year after surgery,and the difference in the AI of each soft tissue landmark before and 1 year after operation was statistically significant(P<0.01 or<0.05).50 common people were selected from the total database,including 25 men and 25 women,a
