Parry Romberg Syndrome

Evidence: Unconfirmed

Names

Progressive hemifacial atrophy (PHA)
Progressive facial hemiatrophy
Idiopathic hemifacial atrophy
Romberg’s syndrome

Description

Parry Romberg Syndrome predominantly affects the skin of the face and is believed to be autoimmune in nature, though the cause is still being researched.  Typically, the skin deteriorates gradually over one side of the face, beginning with the upper jaw and the area extending from the nose to the corner of the lip, and then spreading to other parts of the face.  In some cases, symptoms are not restricted to only one side of the face and may also occur in the trunk or limbs.  Severe cases can spread to the muscles, bones, and cartilage.  Patients can expect symptoms to progress over a period of 2 to 20 years, after which time progression plateaus.  Treatments have so far been unsuccessful in stopping progression, but they do help manage associated discomfort.  Cases that progress over longer periods of time and beginning at a younger age often lead to the most severe symptoms, resulting in facial distortions and nerve disorders.

Prevalence

It is estimated that there are around ~1 case per 700,000 people. 75% of patients are women.

Typical Age of onset
