title: Microvascular free flaps in head and neck cancer surgery in Finland 1986-1995.
abstract: Microvascular free tissue transfer has in many cases replaced classic flap techniques and is now an established workhorse for head and neck reconstructions. In this retrospective study the over 300 patients, who had microvascular free flap reconstructions in head and neck cancer surgery in Finland during a 10-year period (1986-1995) were reviewed. The operations were performed in the University Hospitals by plastic surgeons, ENT specialists or maxillofacial surgeons. The cases consisted of defects resulting from resection of oral cavity tumors (63%), mid- or upper-face and skullbase tumors (20%) and hypopharyngo-esophageal tumors (17%). The series includes a wide range of flap types and analyses flap outcome and complications. A total of 313 cases was reconstructed by 317 flaps (forearm flaps 47%, latissimus dorsi flaps 19%, free jejunum or colon transfers 15%, free iliaca crest flaps 8% and other flaps 11%). Thrombosis of one of the vessels and haematoma were the most frequent causes of failure in microvascular free tissue transfer. A total flap necrosis occurred in 27 (8.5%) and a partial necrosis in 12 (4%) patients. The most reliable flap in terms of survival was the radial forearm flap. The ever-improving success of microvascular free tissue transfer has made it a useful procedure for head and neck reconstructions. There is also a growing need for microvascular team surgery in the field of head and neck cancer therapy.
