Abstract We believe that the myofascial flap is simpler to manage than the free microvascular flaps and safe because of its great vascularization. This flap has some advantages: it is slim, flexible and the fascia in contact with the oral cavity epithelizes in 3 weeks making it resistant to the protolithic action of saliva. The flap is capable of supporting skin grafts and of nourishing bone grafts. The fascia can be pedicled on superficial temporal artery, the temporoparietal fascia provides a versatile source of thin pliable tissue for multiple defects throughout the head and neck and extremities. It is ideal for providing non bulky covering to medium and small areas. The TPFF may be raised as a composite flap incorporating hair-bearing scalp or bone. The pedicle is of adequate length and diameter for free tissue transfer. The muscle can only be pedicled on the deep temporal arteries after its exit from the temporal fossa, sectioning the zygomatic arch and the coronoid apophysis; these maneuvers increase the mobility of the flap, they also increase the rotation arch which is why they can be used in wide or lateral resections. The proximity of the oral cavity, the neck, oropharynx and palate, the middle third of the face, the orbit, and skull base as well as the security of the vascular pedicle make the temporalis myofascial flap very useful for reconstruction in these localizations in one operation. The flap is quickly obtained, it is located close to the operating field and it does not need positional changes. The donor site is closed primarily and the functional deficit is acceptable. |
