Anatomical basis of a new naso-labial island flap

Abstract

We describe a nasolabial island flap with a proximal base. This anatomical study confirms the interest of a proximal base especially with regard to venous return. As opposed to classical naso-labial flaps with subcutaneous pedicle, it has a vascularization of musculo-cutaneous type which allows a greater degree of mobility and reliability. This flap is an effective therapeutic option in surgery for skin defects of the face.

Cervicofacial‐facial artery myocutaneous flap (C‐FAM flap): A novel flap in oral cavity reconstruction

“…Intraoral defects are traditionally covered with local, regional, or free flaps. Local flaps like nasolabial, submental, infrahyoid, platysma flaps, and supraclavicular, are options for reconstruction of small to moderate size defects. Traditionally, nasolabial flap has been described as an axial pattern flap that depends on the angular, infraorbital, transverse facial, and the dorsal nasal arteries of the face.…”

Nasolabial flap reconstruction in oral cancer

“…The nasolabial flap is an axial flap but may be utilized as a random flap [4]. The flap receives its blood supply from the angular artery (a branch of the facial artery), the infraorbital artery, and the transverse facial artery [6]. This rich vascular anastomosis between all the feeding vessels makes it an ideal and versatile flap for reconstruction of the anterior floor of mouth, lips, and nose tip; hence, superiorly, inferiorly, lateral, or medial based flaps can be raised [5].…”

Nasolabial flap

“…4 The angular artery is a branch of the ophthalmic artery that joins the facial artery as it descends inferiorly along the superior lateral aspect of the nose. Along its path it gives off a number of branches, those being the inferior and superior labial arteries, and the lateral nasal artery before it becomes confluent with the angular artery.…”
