The great incidence of advanced squamous cell carcinoma of the mouth, pharynx, larynx and neck, justifies the extensive resections that are carried out by the authors at the Head and Neck Service of Hospital Celso Pierro PUCCAMP - São Paulo. Major pectoralis myofascial flap were used to manage 14 patients with advanced head and neck squamous cell carcinoma of the mouth (ten cases), pharynx (two cases); larynx (one case) and neck (one case). There was no complications in 81.2% and in 18.8% total necrosis of the flap was observed. We conclude that viability, age and necrosis or fibrosis were not associated with the success of this procedure (p=1.0), and previous treatment (chemoradiotheraphy and or radiotherapy alone) had no significant relation with flap viability (p=0.547).
