title: A review of Parry-Romberg syndrome.
abstract: Parry-Romberg syndrome, also known as progressive hemifacial atrophy, is a rare disorder characterized by unilateral facial atrophy affecting the skin, subcutaneous tissue, muscles, and sometimes extending to the osteocartilaginous structures. It has been associated with various systemic manifestations, particularly neurologic, ophthalmologic and maxillofacial. In this article, we review Parry-Romberg syndrome with its associated findings (neurologic, ophthalmologic, cardiac, rheumatologic, endocrinologic, infectious, orthodontic and maxillofacial, and autoimmune), underlying cause, differential diagnoses (en coup de sabre, scleroderma, and Rasmussen encephalitis), and therapeutic options.
