Versatility of bilateral nasolabial flap for reconstruction of subtotal lip defects in oral squamous cell carcinoma with commissural involvement: A case report and review literature.

Abstract

Reconstruction of the lip is crucial to regaining essential functions, including oral competency, speech articulation, and aesthetics. Reconstruction is often challenging when commissure is involved as it affects the anatomy of both the upper and lower lip as well as the size of the oral stoma. Improper commissure reconstruction results in drooling and a reduction in mouth opening. This case highlights the versatility of the simultaneous use of a bilateral nasolabial flap for the reconstruction of subtotal lower-lip defects in cases where a tumor involves one of the commissures, providing satisfactory aesthetic and functional results.
