PURPOSE
This article describes the induced membrane technique (IMT) and presents 10 cases in which the technique was applied for segmental mandibular reconstruction.
METHODS
Ten patients requiring segmental mandibular resection were reconstructed using the staged IMT. Mandibular resection, placement of a reconstruction plate and polymethylmethacrylate spacer, was performed. At the second procedure, the spacer was removed through a small incision and particulate autograft from the ilium was placed, in some cases with bone morphogenic protein.
RESULTS
Nine of the 10 patients achieved bony continuity with the IMT. Spacers were designed to optimize mandibular form and future implant-based restoration. All patients have either had implants placed or have adequate bone for implant placement. The average hospital length of stay for both surgeries combined was 3.1 nights.
CONCLUSIONS
The IMT can be successfully used to reconstruct segmental mandibular defects, allowing surgeons to create a neomandible with optimal form both for facial contour and for dental implant-based reconstruction.
目的
本文介绍诱导膜技术（IMT），并报告 10 例应用该技术进行节段性下颌骨重建的病例。
方法
10 例需要节段性下颌骨切除的患者采用分期诱导膜技术进行重建。行下颌骨切除术、放置重建板和聚甲基丙烯酸甲酯间隔物，然后进行第二次手术，通过小切口取出间隔物，并在某些情况下使用骨形态发生蛋白（bone morphogenic protein，BMP）放置髂骨颗粒自体移植物。
结果
10 例患者中有 9 例通过 IMT 实现了骨连续性。间隔物的设计旨在优化下颌骨的形态，为未来的种植体修复做好准备。所有患者均已行种植体植入术，或有足够的骨质用于种植体植入。两次手术的平均住院时间为 3.1 晚。
结论
诱导膜技术可成功用于重建节段性下颌骨缺损，使外科医生能够为面部轮廓和基于牙种植体的重建创造具有最佳形态的新下颌骨。
