Purpose: Presented is a case of a 45-year-old male patient with defection of cranio-maxillofacial soft tissue caused by a serious traffic accident.Methods: After debridement of the necrotized soft tissue,we used a vascularized free rectus abdominismusculocutaneous flap to reconstruct the maxillofacial soft tissue defection.Results: And two soft tissue expanders were implanted under the scalp 12 days later,while the transplanted rectus abdominismusculocutaneous flap survived.Cicatricial massive scalp defects were repaired by the expanded flaps in secondary operation five months later.Conclusion: Our experience indicates that reconstruction of cranio-maxiilofacial soft tissue defection with rectus abdominismusculocutaneousflaps and scalp expansion is a suitable,cosmetically acceptable method.
