Modified nasolabial flap- the nasomentolabial flap: A new arrow in surgeon's quiver.

Aims And Objectives: To describe an inferior extension of a naso-labial flap as an adjunct to a maleo-labial flap in reconstruction of complete thickness defects around the oral commissure in 2 cases that we performed at our institute.

Methods: Two elderly cases of carcinoma buccal mucosa who underwent wide local excision along with neck dissection had moderately large peri-oral defects that are large to cover with nasolabial flap alone. An inferior extension to the maleo-labial flap was added, making it a naso-mento-labial flap to reconstruct the defects with an acceptable outcome aesthetically and functionally. The reconstructed defects' size was around 7 × 7cms and 8.5 × 6cms full-thickness defect in the buccal mucosa, respectively, with the extension of the defect in both the patients being almost the same with anterior extension to commissure, posteriorly to retro-molar trigone (RMT), laterally full-thickness, medially not involving alveolus.

Results: The incision at the donor site was closed primarily. The reconstruction did achieve the patient acceptable aesthetics, functionality, color and texture. The mean follow up of the patients is around 1 year with no complications.

Conclusion: Naso-mento-labial flap, an inferiorly extended inferiorly based nasolabial flap is a useful addition to surgeon's armamentarium for reconstructing the buccal mucosa and peri-oral defects in patients whose general health prevents the using pedicled or free flaps.
