Traumatic avulsion and reconstruction of the midface.

Traumatic loss of midface soft tissue and supporting structures may result in communication between the oral and nasal cavities. Reconstruction requires both oral and nasal lining, as well as supporting structures. The need for multilaminar tissue, as well as the paucity of local tissue, creates a reconstructive challenge. This case report describes the reconstruction of a traumatic defect of the alveolus, hard palate, inferior orbits, and local soft tissues. An intraoperative alginate mold facilitated a three-dimensional understanding of the wound, and allowed translation of an osseomyocutaneous groin flap to reconstruct the defect in one stage.
