Bilobed Chest Flap (Deltopectoral Skin Flap and Pectoralis Major Musculocutaneous Flap)



Bilobed Chest Flap (Deltopectoral Skin Flap and Pectoralis Major Musculocutaneous Flap)


R. M. MEYER





The bilobed chest flap is a double cutaneous and musculocutaneous flap used for head and neck reconstruction. The flap incorporates the pectoralis major musculocutaneous flap and the medially based cutaneous deltopectoral flap in a single bilobed unit. Both flaps come from the ipsilateral chest and provide for both reconstruction of pharyngoesophageal wall defects and external cutaneous coverage in one stage.

FLAP DESIGN AND DIMENSIONS

The bilobed chest flap is composed of two standard flaps: the pectoralis major musculocutaneous flap and the deltopectoral cutaneous flap. The two flaps share a common base, starting approximately 3 to 4 cm below the medial end of the clavicle and continuing cranially and laterally to the anterior part of the neck. The design of the two flaps resembles an open V (Fig. 221.1). The outline of the musculocutaneous portion of the bilobed flap should be centered on the thoracoacromial artery.
