Modified keystone flap used to repair nose defect after Mohs micrographic surgery


Mohs micrographic surgery (MMS) is a surgical technique used to remove skin tumors with a complete evaluation of the margins. The keystone flap technique is generally used to repair large surgical defects on limbs. We present a case where a modified keystone flap technique was used to close a large defect after Mohs micrographic surgery in a patient with a basal cell carcinoma on the nose. An excellent functional and aesthetic result was obtained with no complications during or after the procedure. We offer a novel indication for this technique for surgical defects in this area.
