General Discussion. Moebius syndrome is a rare neurological disorder characterized by weakness or paralysis (palsy) of multiple cranial nerves, most often the 6th (abducens) and 7th (facial) nerves. Other cranial nerves are sometimes affected. The disorder is present at birth (congenital).
Facial paralysis is a condition that may be present at birth, such as Moebius syndrome, or it may be acquired later in life, such as following removal of facial tumors near the nerves that move the facial muscles. Bellâs palsy is the sudden onset of facial paralysis and is felt to be viral in origin.
