Vertical distraction of fibula transplant in a case of mandibular defect caused by shotgun injury.

This case demonstrates the successful aesthetic and functional reconstruction of a complex facial gun-shot injury with extended bone defects and soft tissue destructions using a 3-step procedure. Initially, a reconstruction plate was inserted, later a fibula transplant enabled the basic reconstruction and finally was distructed in a 3rd session. The rationale behind the sequencing of surgical sessions was the extended bony defect and soft-tissue destruction. The main problem in this type of wound is hypoxia or anoxia of the receptor bed for the transplant. A microvascular anastomosized bone transplant is necessary for sufficient oxygen tension in the recipient site. The anatomical dimensional disproportion of the transplanted free fibula graft and the shape of the mandible were corrected prior to the insertion of dental implants by means of vertical distraction.
