Flap elevation
Flap elevation
The flap is incised and elevated at the level of the subcutaneous fat on its distal edge. Some surgeons may transition to a deeper plane when approaching the proximal pedicle to include muscle fibers from the levator labii superioris alaeque nasi, which increases the vascular supply. The pedicle can retain attachments to the cheek at the superior portion of the most proximal Burowโs triangle (peninsula), or it can be freely mobilized on its subcutaneous pedicle. The former increases the vascular supply, while the latter reduces torsion and allows for easier division and inset. The flap is lifted and rotated counterclockwise for a right-sided defect or clockwise for a left-sided defect. It should cover the defect with no tension.
