Modified Bilateral Perialar Crescent Flap for Reconstruction of Combined Upper Lip and Premaxillary Defect

Many reconstruction methods are performed for combined defects of upper lip and premaxilla in oral cancer patients, which are complicated and multiple staged procedures, compromising the functional or structural unit. In this case report, we present a modification of the bilateral perialar crescent flap for reconstructing the combined defect of upper lip and premaxilla in a single stage. A patient diagnosed with well-differentiated squamous cell carcinoma of premaxilla and upper lip, involving a surgical defect of more than one-third but less than two-thirds of the lip underwent two cycles of neoadjuvant chemotherapy. Later wide local excision of the lesion and simultaneous reconstruction with a modified perialar crescent flap was performed in a single stage. Patient recovered uneventfully and tolerated the procedure well, without any complications. The patient was found to be satisfied with the functional and esthetic result. The reduced upper lip support which was a result of the bony defect of the premaxilla, was corrected with a dental prosthesis. This modification is a useful reconstruction tool for oral cancer patients with combined defects of upper lip and premaxilla.
