Melkersson-Rosenthal syndrome is a neurological disorder characterized by facial swelling, especially of the lips. Partial paralysis may occur, and the tongue may develop folds or furrows.
Symptoms often begin in early adolescence.
The cause of Melkersson-Rosenthal syndrome is unknown. Drug therapy, including steroids, may also reduce swelling. Massage and electrical stimulation may also be prescribed. Melkersson-Rosenthal syndrome may recur intermittently after its first appearance. It may also become chronic.
