Acellular dermal graft pharyngeal repair augmentation after laryngectomy

摘要

Purpose: Pharyngocutaneous fistula (PCF) after laryngectomy continues to be a serious complication, especially after radiation. Recruitment of non-radiated tissue into the surgical defect may decrease the risk of fistula. These techniques however have significant morbidity and increases operative time. We hypothesized that using acellular dermal graft to reinforce the pharyngeal closure could decrease the risk of fistula, without the added morbidity of a vascularized flap.
