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.
