Lower Lip Cancer Managed by Reconstruction with a Double Abbe Flap - A Case Report.

Although the incidence of lower lip cancer is not high in Japan, its treatment requires an approach that considers both esthetics and function. When surgical resection is required, the method used for reconstruction varies depending on the affected part. Despite various studies proposing different types of algorithms, no single method is considered the best. If the loss of half or more of the lip is predicted, a free flap may need to be considered, depending on the case. Here, we report a case involving a 78-year-old edentulous woman with lower lip cancer whose resection area involved approximately 70% of the red and white portions of the lower lip. Fortunately, no resection was required at the commissure. We accordingly performed reconstruction with a double Abbe flap in accordance with a detailed treatment plan. The patient was extremely satisfied with the esthetic and functional outcomes of the surgery.
