Reconstruction of a large lower lip defect using a combination of Abbe and staircase flaps: a case report

  • 1Department of Plastic and Reconstructive Surgery, Gachon University Gil Medical Center, Gachon University College of Medicine, Incheon, Korea


Lip defects often occur following wide excision as a surgical treatment for squamous cell carcinoma of the oral cavity. Defects larger than one-half of the lip cannot be closed primarily and require flap surgery. Reconstruction of the oral sphincter function can be achieved by means of a local flap using the like tissue, rather than with a free flap utilizing different tissues. A defect of the lower lip requires reconstruction using different techniques, depending on its size and location. Herein, we present the case of a patient exhibiting a lip defect spanning more than two-thirds of the lower lip, after a wide resection due to squamous cell carcinoma. The defect was reconstructed using an Abbe flap and a staircase flap. Revision was performed after 16 days. The patient’s oral competencies were fully restored 3 months postoperatively, and the esthetic results were ideal. Based on our experience, a combination of the Abbe and staircase flaps can produce excellent functional and esthetic outcomes in the reconstruction of a lower lip with a large defect. It can serve as a reliable reconstruction option for defects spanning more than two-thirds of the lower lip, not including the oral commissures.
