Abstract
OBJECTIVE: Reconstructive surgery in which a free flap is used following extended resection for head and neck cancer has been popular for more than a quarter of a century. However, postoperative total flap necrosis has not been completely resolved, and few studies have analyzed the specific risk factors for this complication. METHODS: Over a three-year period from 2005 to 2007, 388 flaps were used for reconstructive surgery on 384 patients at Department of Head and Neck of the Cancer Institute Hospital of Japanese Foundation for Cancer Research, and the results for 22 flaps with thrombosis were analyzed. RESULTS: The only statistically significant risk factor for free flap thrombosis was the history of radical concurrent chemoradiotherapy. CONCLUSIONS: It will be necessary to keep this observation in mind when performing salvage surgery following chemoradiotherapy, which is expected to be performed more often in the future.
