The interpectoral fascia flap.
Despite the great number of pedicled and free flaps that are available for defect and contour repair, the number of fascia flaps with an axial blood supply are sparse. Such flaps with their gliding function are mandatory, whenever coverage with very thin, well-vascularized tissue is necessary. To the currently established fascia flaps, (the temporoparietal fascia flap, the radial forearm fascia flap, the lateral arm fascia flap, and the serratus anterior fascia flap), we want to add a new fascia flap, the interpectoral fascia flap. We dissected the interpectoral fascia flap from 20 cadavers. In each of the 40 hemichests, the trunk of the thoracoacromial vessels was selectively injected with red polyurethane and the tissue containing the pectoral branches was separated from the overlying pectoralis major muscle and converted into an independent fascia flap. The maximum flap length was 13.5 cm and the maximum breadth was 10.3 cm. The length of the vascular pedicle before entering the flap was 3.9 cm +/- 1.4 cm with a range of 1.5-6.8 cm. Concerning the arc of rotation, all 40 flaps reached the posterior axillary fold, and 29 flaps (73%) reached the mandibular border. This new fascia flap has applications as pedicled and as free flap. The pedicled flap is used in the neck region, in the axillary region and as gliding tissue between the nipple-areola complex and the pectoralis major muscle. The usage of the fascia flap as a free flap has similar characteristics as the other fascia flaps.
