A rotation flap is a semicircular skin flap that is rotated into the defect on a fulcrum point. The flap must be adequately large, and a large base is necessary if a back-cut will be needed to lengthen the flap. If the flap is too small, the residual defect can be covered by mobilizing the surrounding tissue.

A drawback of rotation flaps is the extended cutting and undermining needed to create the flap, thus increasing the risk of hemorrhage and nerve damage.
