Lip Reconstruction by Double Layer and Double Flap New Combination Technique: A Case Series

In the past, lip reconstruction after ablative surgery has been performed by primary closure and more recently by free flap transfer technique. Cheek’s skin flap has been used to reconstruct the lower lip cutaneous portion. This study presents a reconstructive method for the vermillion and the lip’s cutaneous portion using the Goldstein–Robotti techniques (for the vermillion) and the buccinator flap to reconstruct the cutaneous lip portion and the perioral muscles. This procedure allows a complete reconstruction with a double layer technique for defects of more than one-third of both lips, together or alone, including modiolus, showing satisfactory functionality and aesthetics. The procedure was carried out by splitting the buccinator muscle and elongating the upper and lower buccinator bundles, together or alone. Soft tissue blunt dissection prevented most facial nerves and vessels injuries, ensuring blood supply and an amount of lip sensitivity. Even in the case of facial vessel ligatures after neck dissection, the technique was possible basing the flap pedicle on the internal maxillary artery branches (buccinator) and contralateral facial vessels (orbicularis). We present a case series of six reconstructions of various defects of the upper and lower lips, including the commissure after ablative surgery for squamous cell carcinoma and polymorphous adenocarcinoma. The results showed satisfactory functional and aesthetic outcomes, with similar tissue texture, static and dynamic symmetry achieved for all the patients.
