[Mandibular reconstruction using a vascularized osteocutaneous scapular flap].

Composite tissue defect of the mandible following the surgical resection of head and neck neoplasma or osteoradionecrosis causes functional and cosmetic disorders. Mandibular reconstruction is, therefore, necessary to obtain satisfactory results. The introduction of microvascular surgery has made it possible to transfer various types of vascularized bone grafts and this technique is considered one of the most reliable procedures for mandibular reconstruction. Recently it has been reported that an osteocutaneous scapular flap is useful for mandibular reconstruction. We have performed, over the last 2.5 years, 13 mandibular reconstructions using a vascularized osteocutaneous scapular free flap, and successful results have been achieved. The features of this flap are as follows: 1) it provides a consistent blood supply to the bone and the skin and has a constant vascular pedicle; 2) since the skin island and bone flap have separate pedicles, three-dimensional reconstructions are facilitated; 3) if needed, two skin flaps can be elevated; 4) the skin island is not so bulky; 5) the lateral border of the scapula provides highly vascularized bone of thick cortical density and osteotomies are safely performed; 6) using an angular branch based on thracodorsal artery, a bi-pedicled scapula bone can be raised and two completely vascularized bone segments can be transferred with a single pedicle. Thus, a vascularized osteocutaneous scapular flap has proven very useful for complex mandibular reconstructions.
