Pectoralis Major Muscle and Musculocutaneous Flaps



Pectoralis Major Muscle and Musculocutaneous Flaps


S. ARIYAN





The pectoralis major muscle and musculocutaneous flaps are reliable flaps that can be used for various head and neck defects (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11).




ANATOMY

Although the thoracoacromial artery had been previously described in the literature as running along the undersurface of the pectoralis minor muscle, fresh cadaver dissections confirmed the consistent presence of this vessel along the undersurface of the pectoralis major muscle, with a branch from this vessel to the pectoralis minor. There are additional arteries to the pectoralis major, namely, the lateral thoracic artery to the lateral and inferior portions of the muscle, the superior thoracic artery to the clavicular portion, and the intercostal perforators from the internal mammary artery, providing some supply to the sternal portion of the muscle (2, 20, 21, 22).
