A full thickness excision of the lip involves the surgical removal of tissue from the lip, which is then reconstructed using a local flap technique. This procedure is commonly referred to as an Abbe-Estlander flap, named after the surgical technique that utilizes a cross lip flap for reconstruction. The process begins with the careful marking of incision lines on the lip using a surgical marking pen, ensuring that if the excision is performed to remove a lesion, there is a margin of healthy tissue included around the lesion to promote healing and reduce the risk of recurrence. Local anesthesia, often combined with epinephrine, is administered to minimize discomfort and control bleeding during the procedure. The excision is performed in a precise manner, with incisions made perpendicularly through the cutaneous lip and vermilion on either side of the lesion. This technique allows for the removal of a wedge-shaped section of tissue, which is critical for addressing the defect created by the excision. Following the removal of the tissue, the reconstruction phase begins. Depending on the location of the defect—whether on the upper or lower lip—a specific type of flap is utilized. The Abbe-Estlander flap is particularly notable for its two-stage approach, where the flap is initially created and maintained with its blood supply intact before being transferred to the defect in a subsequent procedure. This meticulous approach ensures optimal healing and aesthetic outcomes for the patient.
