ABBEY ESTENDER FLAP is based on?
|D||Internal maxillary artery|
a. For defects greater than half the central lip, an Abbe flap will give the best result, however, the remainder of the central lip should be excised.
b. The Abbe flap is based on the labial artery and harvested from the central lower lip. For central upper defects, it is elevated to the labiomental fold. For lateral defects, it continues through the chin pad. It is inset above the columella base with extensions to the nasal sill. The flap is divided and inset at two weeks.
c. If the defect is between 1/3 and 2/3 the length of the lip it can be closed by an Abbe flap. The flap was developed by the American plastic surgeon Robert Abbe.
d. It is based on a main artery of the orbicularis oris, the labial artery.
