Congenital (At Birth) Facial Palsy
Babies may be born with facial paralysis and often the cause is unclear. In the past when delivery was performed with forceps, sometimes facial nerve injuries could occur. Congenital facial palsy may appear also as part of a syndrome and involve one or both sides of the face.
Moebius Syndrome is a rare form bilateral facial paralysis in which the sixth cranial nerve (abducens nerve) responsible for lateral motion of the eye is also involved. Moebius Syndrome has varying symptoms and may be difficult to diagnose at birth. Often, additional cranial nerves are involved and sometimes extremities may have abnormalities, chest muscles may be involved, and eyelids, ear, and lip deformities may be seen. Still many patients are healthy. The cause of this syndrome is not clearly known.
