Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare disorder characterized by slow and progressive hemifacial atrophy. The treatment offered for the syndrome generally aims at improving aesthetics. Fat grafts, silicone injections or acrylic prosthesis are alternatives suggested for correction of facial atrophy. Currently, the recommended technique for correction of facial atrophy is cosmetic dermatologic surgery with autologous fat grafting. This study reports a case of Parry-Romberg syndrome and demonstrates that dermatologic surgery can relieve serious damage to the patient's anatomy, starting from the discussion of the therapeutic aspects of the syndrome with emphasis on autologous fat grafting.
