Abstract

Abstract: PURPOSE: To compare the outcomes of an extensive segmental pectoralis major myocutaneous flap (esPMMF) and a conventional pectoralis major myocutaneous flap (cPMMF) in reconstruction of defects after ablative surgery of oral and oropharyngeal cancers. METHODS: The study enrolled 91 patients with primary oral and oropharyngeal cancer who underwent radical resection, followed by reconstruction of the defect using either an esPMMF via the anterior axillary line or a cPMMF. RESULTS: The pedicle lengths of the esPMMF and cPMMF were 22-28 cm and 18-22 cm, respectively. The esPMMF and cPMMF had skin paddle dimensions of 5 cm×8 cm to 7 cm×14 cm and 6 cm×7 cm to 8 cm×17 cm, respectively. The range of shoulder abduction was significantly greater in the esPMMF group and the donor site esthetic results were better. CONCLUSIONS: esPMMF has a longer pedicle flap, enables a greater range of shoulder abduction, and has a better esthetic results than the conventional technique.
