Parry-Romberg syndrome: rare disorder of progressive facial hemiatrophy. Slowly progressive atrophy of the soft tissues of one side of the face, associated with trigeminal neuralgia and involvement of the eyes and hair. Muscles, cartilage and the underlying bony structures may also be involved.
The prevalence is estimated to be at least 1/700,000 individuals, women being slightly more affected than men.
PHA usually presents during the first 20 years of life, characterized by slowly progressive unilateral atrophy of various tissues (skin, connective tissue, fat, muscle and rarely, underlying bony structures) in the territory of the 5th cranial nerve.
Seizures and headaches are the most common neurologic symptoms. Ophthalmologic anomalies (enophthalmos, globe retraction, ptosis, iris heterochromia, uveitis, retinal vasculitis, glaucoma and eyelid atrophy) may result in visual impairment or blindness
1825 – Caleb Hillier Parry included an account of the condition now known as progressive hemifacial atrophy. This description appeared in Collections from Unpublished Papers in 1825, 3 years after his death, published by his eldest son, the physician, Charles Henry Parry.
1871 – Albert Eulenburg (1840–1917), a German neurologist, was the first to use the descriptive term ‘Hemiatrophia facialis progressiva‘ [Progressive Hemifacial Atrophy (PHA)]
