Mandibular Reconstruction of Large Resection Defects By Bone Transport Distraction Osteogenesis – How Far Can We Go?

Objectives – To evaluate the feasibility of reconstructing large mandibular gaps utilizing distraction osteogenesis

Methods - We analyze two mandibular resection defects created after large benign tumors resections. In both cases the mandible was reconstructed by transporting a posterior osseous segment along a reconstruction plate. We analyze the planning process, surgical technique, outcomes and complications

Results – Bone continuity, sufficient in volume for endosseous dental implant placement, was evident at the end of treatment in both cases. Facial symmetry and esthetics were excellent.

Conclusion – Mandibular reconstruction by bone transport is a reliable and reproducible treatment option following resection of benign tumors. Excellent aesthetics and symmetry can be achieved, as well as implant supported oral rehabilitation. This technique is time consuming for the patient but alleviates the need for a donor site and other complex bone grafting procedures.
