Abstract:

Objective: To report a case of ameloblastoma of mandible in our hospital using Masquelet's induced membrane technique (MIMT) to reconstruct mandibular segment defect in February 2021. Methods: According to the principle of MIMT, partial resection and implantation of bone cement were given in the first stage; with the help of digital surgery, three dimension printing model and pre-fabricated titanium mesh were used to transplant the iliac bone in the second stage; the plate and titanium mesh were removed in the third stage. Results: According to the post-operation CT images and intraoperative findings, the bone regeneration shows a good result with MIMT. Conclusion: MIMT can be further studied in the reconstruction of mandibular segmental defect.

摘要：

目的：报道1例2021年2月就诊于我院的下颌骨右侧成釉细胞瘤，采用Masquelet膜诱导技术 （Masquelet's induced membrane technique，MIMT）重建患者下颌骨节段性缺损。方法：依据MIMT原则，给予患者Ⅰ期下颌骨部分切除+骨水泥植入，Ⅱ期依托数字化技术三维打印模型预塑钛网，移植髂骨碎骨块，Ⅲ期拆除重建板及钛网。结果：根据影像学检查及术中所见，应用MIMT修复重建下颌骨节段性缺损效果良好。结论：三维打印与MIMT应用于下颌骨节段性缺损能取得良好的成骨效果，可进一步进行研究。
