Abstract
Although negative-pressure wound therapy (NPWT) for complicated wounds has been extensively studied, it is rarely used in cases involving a submandibular fistula due to radiation-induced osteoradionecrosis of the mandible. This study aimed to investigate the efficacy of NPWT for submandibular fistulas after reconstruction for osteoradionecrosis. Nine patients with submandibular fistulas after reconstruction for osteoradionecrosis treated with NPWT between 2011 and 2014 were included in the study. The wound healing was documented. The NPWT device was removed postoperatively between days 7 and 12 (mean duration, 9.6 days). The wound bed was filled with healthy granulation tissue, and successful healing by second intention was observed in all patients within 2 weeks. No complications were observed. The follow-up ranged from 4 to 27 months (mean, 18 months); the fistulas exhibited excellent healing, and no recurrence or infection was observed. NPWT is a safe, effective technique for managing submandibular fistulas after reconstruction for osteoradionecrosis.
