Pectoralis major myocutaneous flap in Head And Neck Surgery reconstructions: critical analysis.

ABSTRACT Objective: to evaluate the results of the use of the pectoralis major flap in the reconstruction of head and neck surgeries. Methods: we conducted a retrospective study with data bank analysis and review of medical records of patients with head and neck cancer operated at the Discipline of Head and Neck Surgery, Surgery Department, São Paulo Holy Home of Mercy, using the pectoralis major flap for reconstruction, in a period of 16 years. We analyzed age, gender, primary site of neoplasia, clinical staging, preoperative radiotherapy (RT) and complications, classified as major and minor. Results: the series comprised 92 patients, of whom 86 (93.5%) were men; the mean age was 61.39 (±11.35) years; the most common primary sites were the mouth, in 35 cases (38%), oropharynx, in 21 (22.8%), and larynx, in 18 cases (19.6%). The majority of patients were in stage IV (88/92, 95.6%) and only four (4.3%) had preoperative RT. The overall complication rate was 48.9%, but only 6.5%, characterized as major complications. In the univariate statistical analysis, we found no factors related to the occurrence of complications. Only the primary neoplasm site presented marginal significance (p = 0.06). Conclusion: the pectoralis major flap is safe, with few complete and effective losses in reconstructions in head and neck surgeries, with low rates of major complications, being an option to be considered.
