Definition/Description
[edit | edit source]

Moebius, or Möbius, syndrome is defined as congenital facial palsy combined with abnormal ocular abduction. It is a rare congenital condition that was first described by German neurologist Paul Julius Möbius in 1888[1].

Moebius syndrome is due to the loss of function of motor cranial nerves. Most cases are diagnosed during infancy. The disease is not progressive.

Clinically Relevant Anatomy

Please see the Facial Nerve and Facial Palsy pages for information on the anatomy of the facial nerve.

Mechanism of Injury / Pathological Process
[edit | edit source]

The etiology of Moebius syndrome is not known, but it appears to be multifactorial. There has been evidence of a genetic component related to various loci on chromosomes 3, 10, and 13[2].
