Microsurgery for macrodefects: microvascular free-tissue transfer for massive defects of the head and neck

Abstract

Despite defect location and the fear of creating complex massive defects, coverage of large areas of soft tissue loss, with or without exposed calvaria, dura, and brain, can be reconstructed reliably with microvascular free tissue transfer. This technique permits separation of the oronasopharynyx from the intracranial contents, coverage of dural grafts, restoration of composite tissue loss, and achievement of superior aesthetic results in a single stage. When choosing vascular anastomotic sites, free-flap transfer permits a greater latitude in flap orientation, tailoring, and inset than is possible when using fixed pedicled rotation flaps. When confronted with a deeply invasive or gigantic malignancy, a multidisciplinary team approach is optimal. The risk associated with sophisticated ablative and reconstructive operative procedures is justified when dealing with potentially curable lesions. The success of these extensive procedures is related not only to the functional result and the aesthetic appearance, but most importantly to the resultant quality of life they allow.
