ABSTRACT
The facial artery musculomucosal flap, technically a combination of the nasolabial flap and the buccal mucosal flap, has been a reliable, versatile flap, either superiorly or inferiorly based for reconstruction of a wide variety of postcancer excision intraoral mucosal defects including defects of the palate, alveolus, lips and floor of mouth. We have used it 17 times in 16 patients with no failures and one flap with terminal necrosis. Almost all flaps developed venous congestion which settled on its own by conservative management.

The progression of submucous fibrosis to oral cancer is well established. This condition in an advanced stage causes progressive trismus. Oral cancers associated with severe submucous fibrosis (interincisor distance [IID] < or = 1.5 cm) require bilateral buccal mucosal reconstruction after tumor excision. After wide excision of the tumor, a regional flap is used to reconstruct the buccal mucosal loss on that side. The opposite buccal mucosa, afflicted by advanced submucous fibrosis, is released at the same time to open the mouth and is resurfaced by an ipsilateral, inferiorly based nasolabial flap. This helps to rehabilitate the oral cavity completely and to prevent the recurrence of trismus. In 18 months, 12 patients underwent total reconstruction of intraoral tumors associated with submucous fibrosis. The average preoperative IID was 0.875 cm. All patients had inferiorly based, two-stage nasolabial flaps for submucous fibrosis reconstruction. The average pain-free postoperative IID was 3.13 cm.
