The rectus abdominis myocutaneous flap combined with vascularized costal cartilages in reconstructive craniofacial surgery.

Abstract

The efficacy of osteocutaneous or vascularized bone flaps for reconstruction of massive skeletal and soft-tissue defects has been supported by recent descriptions in the literature. In this article we presented an alternative technique, which is the rectus abdominis myocutaneous flap combined with vascularized eighth and ninth costal cartilages, for reconstruction of midfacial composite defects. The vascular pedicle of the composite flap is the deep inferior epigastric artery and vein. The costal cartilages are supplied by the perichondrial vascular network through the anterior intercostal vessels connecting with the deep epigastric vascular system. Vascularized costal cartilages are considered to reduce the incidence of postoperative complications and resorption of this material. This technique is a useful tool for restoration of craniofacial contour in reconstructive head and neck surgery.
