Melkersson–Rosenthal syndrome is a rare neurological disorder

Neurological disorder

A neurological disorder is a disorder of the body's nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord, or in the nerves leading to or from them, can result in symptoms such as paralysis, muscle weakness, poor coordination, loss of sensation, seizures,...

 characterized by recurring facial paralysis

Paralysis

Paralysis is loss of muscle function for one or more muscles. Paralysis can be accompanied by a loss of feeling in the affected area if there is sensory damage as well as motor. A study conducted by the Christopher & Dana Reeve Foundation, suggests that about 1 in 50 people have been diagnosed...

, swelling of the face and lips (usually the upper lip), and the development of folds and furrows in the tongue. Onset is in childhood or early adolescence. After recurrent attacks (ranging from days to years in between), swelling may persist and increase, eventually becoming permanent. The lip may become hard, cracked, and fissured with a reddish-brown discoloration. The cause of Melkersson–Rosenthal syndrome is unknown, but there may be a genetic predisposition. It can be symptomatic of Crohn's disease

Sarcoidosis , also called sarcoid, Besnier-Boeck disease or Besnier-Boeck-Schaumann disease, is a disease in which abnormal collections of chronic inflammatory cells form as nodules in multiple organs. The cause of sarcoidosis is unknown...

.

Treatment

Treatment is symptomatic and may include medication therapies with nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids to reduce swelling, as well as antibiotics and immunosuppressants. Surgery may be recommended to relieve pressure on the facial nerves and to reduce swollen tissue, but its effectiveness has not been established. Massage and electrical stimulation may also be prescribed.

Prognosis

Melkersson–Rosenthal syndrome may recur intermittently after its first appearance. It can become a chronic disorder. Follow-up care should exclude the development of Crohn's disease or sarcoidosis.

Research

The NINDS supports research on neurological disorders such as Melkersson-Rosenthal syndrome. Much of this research is aimed at increasing knowledge of these disorders and finding ways to treat, prevent, and ultimately cure them.
