Abstract:
Until recently, cranial base tumors or midfacial tumors were deemed unresectable due to an inability to accurately diagnose the extent of the involvement and to approach and excise the tumor safely. With refinements in CT and NMR scanning, as well as the development of craniofacial technique, reconstruction has become absolutely crucial in allowing successful resection of these tumors. Resection of these tumors may sometimes result in massive and complex extirpation defects that are not amendable to local tissue closure. In such cases, free tissue transfer was an effective alternative because it can provide a large amount of well-vascularized tissues arts reliable separation of the intracranial space from bacterial flora of the upper airway. Microvascular free tissue transfer was used in 15 patients at our center to reconstruct the cranial base and/or midfacial defects. Of these 12 were free rectus muscle flaps, 2 were free latissimus dorsi muscle flaps, 1 was a free scapular osteocutaneous flap and 1 was a free scapular fasciocutanegus flap. There were 2 cases of total flap loss. In those cases, revisions were performed using latissimus dorsi muscle free flap in one case and STSG in the other. One patient had a postoperative cerebrospinal fluid leak which was spontaneously resolved by conservative management. The large complex defects were successfully reconstructed by one-stage operation and the functional and esthetic results wee satisfactory with acceptable complication rates.
