数字化技术辅助下颌骨修复重建的临床疗效分析

Clinical Efficacy of Digital Technology Assisted Mandible Reconstruction

目的:分析数字化技术辅助下颌骨修复重建的临床疗效。方法:选择笔者科室2016年1月-2017年6月收治的15例下颌骨缺损患者,术前选择螺旋CT扫描下颌骨,经计算机辅助手术设计,3D打印技术得到个体化模型及手术导板,利用模型及手术导板,根据手术方案制备游离腓骨瓣并切除病变下颌骨,将腓骨瓣移植修复下颌骨缺损。记录手术时间、创面愈合、并发症、面部外形恢复情况。结果:15例患者依据术前三维图像及数据均制备了与下颌骨缺损切除部位相匹配的修复假体模型、手术导板,创面均一期愈合,术中均未见穿孔,术后患者未发生排斥反应及麻木表现。术后定期全景片或CBCT检查移植骨愈合良好,无患者因感染等因素取出假体,面部外形均恢复良好。结论:数字化技术辅助下颌骨修复重建的临床疗效肯定,可较好地实现精确化、个体化修复。

Objective To analyze the clinical effect of digital technology assisted mandible reconstruction.Methods15patients with mandibular defects who treated from June2015to January2017in our hospital,spiral CT was selected to scan the mandible before operation,computer-aided design,3D printing technique was used to obtain the individualized model and the surgical guide plate,used the model and surgical guide,according to the surgical plan to prepare the free fibula flap and remove the diseased mandible,to repair the mandible defect with fibular flap.then operation time,wound healing,complications and facial appearance recovery was recored.Results In the15cases,according to the preoperative three-dimensional images and data were prepared with mandibular defect resection site matching prosthesis model,surgical guide the wound healing was the first phase,there was no perforation in the operation,and no rejection or numbness occurred after the operation.Postoperative,periodic panoramas or CBCT examination of graft bone healing was good,no patient took out the prosthesis due to infection,the facial appearance all recovered well.Conclusion Curative effect is sure of digital technology aided mandibular reconstruction,it can be better actualized and individualized.
