Lips are structures that play an essential role in aesthetics and in different functions such as nutrition and speech. The complex anatomy of the lips - with three different layers composed of skin, mucosa, and muscles - makes surgical management of this area a therapeutic challenge. The use of flaps for the reconstruction of large defects with low risk of necrosis is possible given the abundant blood supply of the lips. We report a case of surgical reconstruction of the lower lip after the excision of a severe squamous cell carcinoma using a skin-mucosa Abbe-Estlander flap with a satisfactory final outcome.
