What is and what causes Parry-Romberg syndrome?
Parry-Romberg syndrome is a rare disorder characterized by slowly progressive deterioration (atrophy) of the skin and soft tissues of half of the face (hemifacial atrophy), usually the left side. It is more common in females than in males.
What are the signs and symptoms of Parry-Romberg syndrome?
Initial facial changes usually involve the tissues above the upper jaw (maxilla) or between the nose and the upper corner of the lip (nasolabial fold) and subsequently progress to the angle of the mouth, areas around the eye, the brow, the ear, and the neck. The deterioration may also affect the tongue, the soft and fleshy part of the roof of the mouth, and the gums. The eye and cheek of the affected side may become sunken and facial hair may turn white and fall out (alopecia). In addition, the skin overlying affected areas may become darkly pigmented (hyperpigmentation) with, in some cases, areas of hyperpigmentation and patches of unpigmented skin (vitiligo). Parry-Romberg syndrome is also accompanied by neurological abnormalities including seizures and episodes of severe facial pain (trigeminal neuralgia).
At what age does Parry-Romberg syndrome occur?
The onset of the disease usually begins between the ages of 5 and 15 years. The progression of the atrophy often lasts from 2 to 10 years, and then the process seems to enter a stable phase. Muscles in the face may atrophy and there may be bone loss in the facial bones. Problems with the retina and optic nerve may occur when the disease surrounds the eye.
Is there any treatment for Parry-Romberg syndrome?
There is no cure and there are no treatments that can stop the progression of Parry-Romberg syndrome. Reconstructive or microvascular surgery may be needed to repair wasted tissue. The timing of surgical intervention is generally agreed to be the best following exhaustion of the disease course and completion of facial growth. Most surgeons will recommend a waiting period of one or two years before proceeding with reconstruction. Muscle or bone grafts may also be helpful. Other treatment is symptomatic and supportive.
What is the prognosis for Parry-Romberg syndrome?
The prognosis for individuals with Parry-Romberg syndrome varies. In some cases, the atrophy ends before the entire face is affected. In mild cases, the disorder usually causes no disability other than cosmetic effects.
What research is being done for Parry-Romberg syndrome?
The NINDS supports research on neurological disorders such as Parry-Romberg syndrome with the goal of finding ways to prevent, treat, and cure them.

Genetic Diseases (Disorder Definition, Types, and Examples)The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Heterochromia IridisHeterochromia iridis is a rare condition that describes people with two different colored eyes. There are many potential underlying causes of heterochromia iridis including genetic and acquired conditions. Heterochromia iridis comes in three types: sectorial heterochromia, central heterochromia, and completely heterochromia. The condition is often recognized by a parent (in the case of an affected infant) or by the patient or a family member (acquired heterochromia iridis). Treatment includes addressing the underlying condition or wearing tinted contact lenses to make the eyes look more uniform. The majority of people with heterochromia iridis have an excellent prognosis.
Optic NeuritisOptic neuritis is inflammation of the optic nerve, the structure that connects the eye to the brain. The precise cause of optic neuritis is unknown, but it is thought to be a type of autoimmune disorder. Optic neuritis most commonly develops due to an autoimmune disorder that may be triggered by a viral infection.
Seizure (Epilepsy)Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Seizures Symptoms and TypesSeizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Trigeminal NeuralgiaPain that originates in the face is referred to as trigeminal neuralgia. This pain may be caused by:
- an injury,
- an infection in the face,
- a nerve disorder, or
- it can occur for no known reason.
VitiligoVitiligo is a condition in which the skin turns white due to the loss of pigment from the melanocytes, cells that produce the pigment melanin that gives the skin color.
