Transient recycling of resected bone to facilitate mandibular reconstruction – A technical note

Abstract

Mandibular reconstruction requires considerable sculptural skills. The intriguingly complex configuration of the structure is difficult to reproduce. It is thus imperative for surgeons to seek a technique that improves the precision of the reconstruction. A 55-year-old male presented with a full thickness cancer (T4+) of his left cheek. Radical ablative surgery resulted in an extensive loss of bone and soft tissue mandating major reconstruction. The resected bony specimen was thoroughly denuded, autoclaved, and then placed back into its original site so that the mandible resumed its pre-surgical configuration. A reconstruction plate was applied to maintain structural stability, then the "recycled bone" was used as a template and replaced with a free fibular graft. The patient fared well and a follow-up panoramic radiograph demonstrated good alignment and symmetry of the reconstructed mandible. This method is a viable option for segmental mandibulectomy defect repair in selected cases. Using this technique, it is possible to restore the original bony contour expediently and accurately.
