Parry-Romberg syndrome and sympathectomy--a coincidence? 
Abstract Parry-Romberg syndrome is a clinical entity consisting of progressive hemifacial atrophy appearing at a young age. Animal studies indicate that sympathectomy can produce hemifacial atrophy. To our knowledge, this is the first report of a patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy.

Parry-Romberg syndrome is a clinical entity consisting of progressive hemifacial atrophy appearing at a young age. Animal studies indicate that sympathectomy can produce hemifacial atrophy. To our knowledge, this is the first report of a patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy. 

Parry Romberg Syndrome 
Progressive facial wasting disorder 

Parry Romberg syndrome is a disorder that affects the face and nervous system. It typically becomes apparent during childhood or young adulthood (ages 5 to 15 years) when the soft tissue of one side of the face (usually the left) begins to waste away. 

Symptoms 
Generally the first sign is facial changes above the upper jaw or between the nose and upper corner of the lip. As the soft tissue and fat begin to shrink, the skin starts to sink in and distort the face. Over the next three to five years, the mouth, eyebrow, ear, and cheek on the affected side begin to change as well. 

In addition to the facial changes, the person with Parry Romberg syndrome may also experience face pain, especially in the mouth, cheek, and nose (trigeminal neuralgia), as well as migraine headaches and seizures. The hair on the affected side of the head may turn white and the eyelashes and eyebrow on that side may fall out. The skin over the affected side may turn dark with light patches (vitiligo). The severity of the symptoms varies from person to person.
