    Abstract:
    The ideal reconstructive method for the buccal mucosa should provide durable, stable coverage and a natural contour, while simultaneously minimizing morbidity of both the defect and donor sites. Since the first report of the anterolateral thigh flap in 1984, it has become one of the most commonly used flaps for the reconstruction of various soft-tissue defects. From March 2004-April 2005, 24 free anterolateral thigh flaps were used to reconstruct buccal defects, including the retromolar trigone and as far as the oral commissure, and in some cases with extension to the neighboring palatal region and tongue. The study comprised 1 female and 23 male patients, with ages ranging from 26-63 years (mean age, 45.8 years). Two flaps required reoperation due to vascular compromise, and both were salvaged with arterial and venous anastomosis revisions, giving an overall success rate of 100%. Primary thinning of the flap was performed in 10 cases. In 2 cases, additional vastus lateralis muscle was included in the flap to fill the large defect. In 2 cases, marginal necrosis with dehiscence of the flap was observed, one of these patients having a history of atherosclerosis and diabetes mellitus (marginal skin necrosis and infection of the donor area were also observed in this patient). In 2 patients, seroma collection was observed in the neck at the dissection site. Chart reviews showed that most patients had a history of betel-nut chewing (95.8%) or a combination of smoking and betel-nut chewing (79.2%). During the follow-up period of 4-12 months, a sufficient level of mouth-opening with interincisal distances of 34 mm, 44 mm, and 48 mm was achieved in all 3 cases reconstructed after release of the trismus. Although it has some variations in the vascular pedicle, irregularity in derivation from the main vessels, and minimal morbidity of the donor site, the anterolateral thigh flap, with its evident functional, structural, and cosmetic advantages, can be considered an excellent and ideal flap option, and a first choice for most buccal defects.
