Electroconvulsive therapy during pregnancy as a possible cause of Möbius syndrome: additional clinical observation.

Möbius syndrome is a rare congenital disease with a prevalence of between 0.0002 and 0.002% of births. Minimum diagnostic criteria for this disease include congenital unilateral or bilateral facial and abducens nerve paresis. Occasionally, the cranial nerves V and VIII are affected. If cranial VIII is affected, the person experiences hearing loss. Other findings in these patients that are not part of the diagnostic criteria include the involvement of other cranial nerves, malformations of orofacial structures, reductive limb anomalies, and defects of the chest wall. We herein report a newborn case with Möbius syndrome.
