The surgical flap shown in the photograph above represents Abbe flap.
In 1898, Abbe first described the lip switch flap (Abbe flap), which was originally designated as a complete philtral reconstruction for the relief of the bilateral cleft lip deformity. The use of this flap has been liberalized, and today it is quite useful and a versatile means of both lower and upper lip reconstructions. The flap can be taken from either lip, and its shape and size are dependent on the defect. Typically, a flap half the size of the defect is adequate because the change of length of both lips is symmetric. The flap is incised full thickness with care at the vermilion border of one side to leave it pedicled on a small amount of mucosa and the labial artery. A meticulous 3-layer closure at both the donor and recipient sites is standard. Two stages are required because the pedicle must be ligated and inset at approximately 3 weeks after the principle procedure.
