Irradiation of the recipient site does not adversely affect successful free flap transfer in the repair of head and neck defects after salvage surgery for recurrent nasopharyngeal carcinoma originally treated with radiotherapy

Abstract

Irradiation of the recipient site has been associated with postoperative complications and an increased rate of flap failure in facial reconstruction. The aim of this study was to report the outcomes of our use of four different types of flaps (two free and two pedicled) for the reconstruction of patients with nasopharyngeal carcinoma (NPC) treated with radiotherapy, who subsequently received salvage surgery after the development of recurrence or secondary primary tumours. The records of 12 NPC patients who underwent salvage surgery and reconstruction from 2002–2007 were retrospectively reviewed. There were no intraoperative or significant postoperative complications. All flaps survived. The average cosmetic outcome was 2.7 (1 = poor, 4 = excellent), all patients could tolerate a liquid to normal diet, and nine patients had normal or intelligible speech, while three exhibited slurred speech. These results indicate that the effects of irradiation on the recipient site do not appear to adversely affect successful flap transfer or outcomes.
