Medical Intelligence & Overview
Melkersson's syndrome, also known as Melkersson-Rosenthal syndrome, is a rare neurological condition characterized by recurring facial swelling, facial muscle weakness or paralysis, and a fissured tongue. This syndrome can vary significantly in its presentation, with some individuals experiencing only certain symptoms, while others may display all three. It primarily affects the facial nerves and tissues, leading to the distinct features associated with the disorder. Although the exact cause remains unknown, ongoing research suggests a combination of genetic, environmental, and immune factors might contribute to its development.
Causes & Symptoms
