Moebius Syndrome: What We Know So Far

Area of Science:

• Neurology
• Genetics
• Developmental Biology

Background:

• Moebius syndrome (MBS) is a rare congenital cranial nerve disorder.
• It is characterized by facial (VII) and abducens (VI) nerve palsies.
• Potential causes include genetics and intrauterine vascular disruptions.

Purpose of the Study:

• To review the etiology, presentation, diagnostic approaches, and management of Moebius syndrome.
• To examine the clinic-pathological aspects of MBS.
• To synthesize current literature on MBS.

Main Methods:

• A comprehensive literature review was conducted.
• The PUBMED database was used to identify relevant studies.
• Keywords were used to filter and reference literature.

Main Results:

• The leading theory for MBS etiology is intrauterine brainstem vascular disruption, followed by genetic factors.
• Facial and abducens nerve palsies are common, but other cranial nerves and anomalies can be affected.
• Diagnosis is primarily clinical, though brain imaging may show characteristic features.

Conclusions:

• Moebius syndrome is diagnosed clinically, despite potential radiological findings.
• There is no cure, necessitating a personalized, multidisciplinary approach for supportive care.
• Standardized management guidelines are needed to address physical and psychological deficits.
