Progressive hemifacial atrophy, also known as Parry-Romberg syndrome (PRS), is an uncommon condition that causes slow and progressive unilateral soft-tissue atrophy of the face. This atrophy affects the skin and subcutaneous tissue, including fat and muscle, and in some cases, may also involve the underlying bone and muscle. The exact cause of this syndrome is unknown, but several possible factors have been suggested. These include genetic predisposition, autoimmune responses, and infections or trauma. We report a case of a young female who presented with an asymptomatic one-sided atrophy of the face for the last ten years. This case highlights autologous fat grafting as a safe and effective option for restoring facial symmetry in PRS.
