Chen WL, et al. - A comparative assessment was conducted of the consequences of an extensive segmental pectoralis major myocutaneous flap (esPMMF) and a conventional pectoralis major myocutaneous flap (PMMF) in oral and oropharyngeal cancer. The findings disclosed that the esPMMF presented with a longer pedicle flap. It enabled a greater range of shoulder abduction and reported a better aesthetic result, in contrast, to the conventional technique.
