Frontonasal Myocutaneous Flap Based on the Transversus Nasalis Muscle

In 1997, Maruyama and Iwahira proposed an axial frontonasal flap based on the lateral branch of the angular artery to cover defects of the distal third of the nose. In this article, we presented a modification to the flap suggested by Maruyama and Iwahira, with the pedicle including the transverse part of the nasal muscle to make the advancement safer in terms of survival of the flap. We believe that the axial myocutaneous flap of the nasal dorsum is a viable repair procedure for soft-tissue loss of the distal third of the nose (including the nasal tip and the alae nasi to the nasolabial fold), because it is easy and especially safe to perform.
