Use of pectoralis major myofascial flap on the prevention of pharyngocutaneous fístula in salvage laryngectomy after chemoradiotherapy.

Pharyngocutaneous fístula (PCF) is a major complication of salvage laryngectomies, mainly secondary to the effect of radiotherapy. Our main objective is to study the effect of pectoralis major myofascial flap (PMMF) on the prevention of PCF. We studied all total laryngectomies (TL) performed between 2001 and 2018, noting the use of previous chemoradiation, the type of suture and the use of flaps.
