Abstract

Head/neck cancer resections often require reconstruction to restore form and function. Small-to-medium size intraoral defects can be successfully reconstructed by local pedicled flaps, such as the facial artery musculomucosal (FAMM) flap,1 which encompasses different layers: cheek mucosa and submucosa, the underlying layer of the buccinator muscle, a portion of the orbicularis oris close to the labial commissure, and the facial artery.2 The flap is usually outlined longitudinally over the facial artery course, and average size is 5 × 2.5 cm. We describe here an innovative flap design and dissection, apt to treat larger defects than the usual ones. Go to: METHODS In a 50-year-old patient with squamous carcinoma of the soft palate involving also surrounding oral soft tissue, after oncological resection, we designed on the cheek mucosa an 8 × 3 cm flap with a squamous carcinoma orientation. The flap axis was crossing about 90 degrees the projection of the facial vessels. Dissection was carried out in anteroposterior direction and the facial artery skeletonized in continuity 3.5 cm superiorly and inferiorly the flap entrance (Fig. ​(Fig.1).1). Once the vascular pedicles had been mobilized and the labial artery ligated, the transverse (t)-FAMM flap was transposed superoposteriorly and sutured to the residual mucosa of the hard palate. A contralateral t-FAMM flap was harvested and transposed. The whole soft palate was then reconstructed by suturing the 2 flaps together.
