Flap elevation and mobilization
Flap elevation and mobilization
An incision is made along the anterior border and both sides of the flap. The skin is elevated above fascia at the mastoid process or above perichondrium on the posterior ear and postauricular sulcus. The distal portion of the flap may be thinned, but a thin layer of adipose should remain on the flap to ensure viability. Meticulous hemostasis is important because visualization will be difficult after the flap is placed. The flap is then draped over the defect. Both the primary and secondary defects can be undermined slightly to increase mobility.
