The authors report a case of facial hemiatrophy, secondary to linear scleroderma, and review the various possible causes of facial hemiatrophy. The various treatments proposed to correct facial hemiatrophy are described. The advantages and disadvantages of each technique together with their indications as a function of the severity of the lesions are then discussed. Free flap currently appears to be the treatment of choice in severe forms and the main question concerns the choice of flap. The authors prefer an inverted dermal fat flap because of its advantages (absence of long-term ptosis, better facial contours) and the absence of laparotomy.
