摘要
目的收集应用计算机辅助设计与制造技术修复下颌骨缺损患者的手术治疗过程,进行数据归纳与经验总结。方法选取自2015年在中国医科大学附属盛京医院口腔颌面外科病房住院患者中,应用计算机辅助设计技术进行术前设计、模拟、材料预制的患者,共6例;选取自2010—2014年住院行游离血管化肌皮骨瓣手术修复颌面部软硬组织缺损的患者共16例(手术17次),作为对照组。查阅病历及影像资料,统计住院时间、手术时间等数据,并通过SPSS 19.0软件对数据进行统计学比较。结果通过对数据的统计分析,术前准备时间比较,病例组和对照组(顺序下同)分别为(7.83±1.94)d、(8.00±4.43)d,其差异无统计学意义(P>0.05),提示计算机辅助设计的应用并未延长术前准备时间;平均住院时间为(19.20±1.30)d和(23.00±9.74)d,其差异无统计学意义(P>0.05)。结论计算机辅助设计的应用,在常规术前准备时间内即可完成个性化部件制作,并未出现延误手术的现象,减少了术中操作步骤,简化了流程,进而缩短了手术时间;在未出现严重并发症时,新技术的应用对治疗周期影响并不显著。
Objective Tosummarize the data and experience ofcomputer-aided design and manufacturing technology（CAD/CAM）in repairment of mandibular defects. Methods Six patients admitted to the oral and maxillofacial surgery ward of Shengjing Hospital from2015 to the present were selected. The CAD/CAM technology was utilized in the preoperative plan, simulation, and material prefabrication.From 2010 to 2014, 16 patients with maxillofacial soft and hard tissue defect who underwent the free vascularized muscle cutaneous bone flap surgery（17 operations） were selected as the control group. The patients′ medical records and images were collected. The length of hospital stay, preoperative preparation, and duration of operation were also taken into account. All data were analyzed by SPSS 19.0 software. Finally, a representative case was selected to make an introduction. Results Through the statistical analysis of the cases′ data,the average duration of preoperative preparation in experimental group and control group was（7.83 ±1.94） and（8.00 ±4.43） days, respectively（P0.05）. The average length of hospital stay in the experimental and control groups was（19.20±1.30） and（23.00±9.74） days,respectively（P0.05）. No significant differences were found between the two groups. The above results indicated that our new technology did not extend the preoperative preparation duration or hospital stay length. Conclusion The（CAD/CAM） can be utilized in personalized component making in routine preoperative preparation. No delay occurred in the operations. This method reduced the intraoperative steps,simplified the process, and shortened the operation duration. In the absence of severe complications, the application of new technology has no significant impact on the treatment cycle.
