摘要
目的探讨应用数字化导板辅助重建钛板精准复位及固定下颌骨粉碎性骨折的方法及效果。方法选取本院2016年1月—2017年12月收治的10例下颌骨粉碎性骨折患者作为研究对象,所有患者术前应用数字化外科技术设计手术导板并行3D打印,术中手术导板辅助重建钛板精准复位及固定下颌骨粉碎性骨折,术后行图像融合及临床评价。结果所用患者均一期愈合,图像融合显示与术前虚拟设计偏差度<2 mm,咬合关系恢复及骨折复位愈合情况良好,张口度未见异常。结论数字化导板辅助下颌骨粉碎性骨折复位及固定,缩短了手术时间,能精准复位及固定下颌骨粉碎性骨折,临床应用效果确定。
Objective To discuss the methods and efficacy of digital guide to assist accurate reduction and fixation of mandibular comminuted fracture.Methods 10 patients of mandibular comminuted fracture from January 2016 to December 2017 were involved.Preoperative design was made by digital technology and surgery guides were manufactured using 3 D printer.By means of surgery guides,mandibular comminuted fractures were fixed with reconstruction titanium plate in surgery.Image fusion and clinical evaluation were conducted to investigate treatment after surgery.Results Primary healing was obtained in all patients.Image fusion showed a less-than-2 mm deviation.Occlusion relation recovery and reduction of fracture were in good condition,and nothing abnormal was detected in the mouth opening.Conclusion Surgery guide can shorten the operation time,precisely restore mandibular comminuted fractures and has definite clinical application efficacy.
