Pectoralis major myocutaneous flap for faringeal defects reconstruction. Case report

Abstract

Introduction: Pharyngocutaneous fistula after total laryngectomy (TL) remains a hardly frequent complication especially after radiotherapy. When conservative measures fail, reconstructive procedures are necessary. Our institution has adopted the pharyngeal interposition graft (PIG) using a pectoralis major myocutaneous flap (PMMC), which has adequate blood flow, for treatment post-irradiation pharyngocutaneous fistula. Description: We present a case-patient with a pharyngocutaneous fistula after TL that requires an externsive reconstruction by PMMC flap and the important role of hyperbaric oxygen therapy in the management of radiation-induced injury. Conclusions: In this era of microvascular reconstruction, the PMMC flap can safely be used for reconstruction of head and neck defects, providing cover to pharyngeal repair following salvage laryngectomy in patients who are high risk for free flaps after organ preservation protocols or patiens with a history of vascular disease.
