[The infrahyoid musculocutaneous flap. Anatomic bases and the results of a preliminary experience in cervicofacial oncology].

The infrahyoid myocutaneous flap has been described by Wang in 1986. Its blood supply comes from the superior thyroid artery. This flap consists of sternohyoid muscle, sternothyroid muscle, superior belly of omohyoid muscle and a skin pad from the medial infrahyoid area. Thanks to its arc of rotation, this flap is appropriate for the repair of mucosal defects of the tongue, floor of the mouth, retromolar region, interior side of cheek, oropharynx, hypopharynx and in the face, skin defects of the exterior side of cheek, parotid region and lower lip. The infrahyoid myocutaneous flap has obvious interest in head and neck reconstruction surgery given its versatility and the quality of its cosmetic results.
