pectoralis major
Large chest wall muscle commonly used for implant coverage and flap harvest in reconstructive surgery.
Full Definition
The pectoralis major is a large, fan-shaped muscle of the anterior chest wall that plays a central role in breast reconstruction. It can provide coverage for subpectoral implant placement, serve as a recipient site for flap inset, or be harvested as a pedicled muscle flap for coverage. The muscle's dual nerve supply and robust blood supply make it reliable for reconstructive purposes. Understanding pectoralis major anatomy is crucial for avoiding complications like animation deformity and achieving optimal reconstructive outcomes.
Usage
Usage note: Often abbreviated as 'pec major' in surgical notes.
