Two Cases of Reconstruction with Modified Keystone Flap on the Lower Extremity / 대한피부과학회지

Even though several techniques are available for repairing lower extremity skin defects, it is hard to challenge the advantages of local flaps (advancement, rotation, or transposition) due to lack of skin laxity of lower extremities. Modified keystone flap (MKF) is a simple and effective method of closing a large skin defect. It is especially useful for wound closure in circumstances where the defects show limited skin laxity. Compared to the keystone flap (KF), MKF has many advantages, including quick healing time, high flap viability, minimal postoperative pain, and excellent aesthetic results. Here, we report two cases of reconstruction of large skin defects of the lower extremities using MKF with satisfactory results.
