Mandibular condylar-ramal reconstruction using vascularised costochondral graft based on the serratus anterior composite flap

摘要

Background: Nonvascularised autogenous costochondral rib grafts are the gold standard for replacement of the mandibular ramus and condyle. However, condylar defects present a difficult condition to treat when soft tissue defects are involved. Thus, we used vascularised costochondral grafts (VCGs) with a cartilaginous cap based on the serratus anterior muscle flap to reconstruct these composite defects. The purpose of this study was to evaluate the advantages and effectiveness of VCGs based on long-term observation.
