Skin tumors often occur in the face or other sun-exposed areas in the aged population, and cancerous ulceration in the face leads to facial damage. Regarding the aesthetic character of the facial unit and the age or concomitant pathologies of these patients, it is necessary to use quick, reliable methods to debride malignant ulcer and cover the wound or suture the incision. We report 2 cases of large facial malignant ulcer that were treated with forehead flap based on the supratrochlear artery or the frontal branch of a side superficial temporal artery in a 1-stage operation. Both of them got satisfying functional and aesthetic results.
