There have been many causes associated with bilateral vocal cord palsy, both congenital and perinatal. Until now, the main congenital causes of bilateral vocal cord palsy have been associated with meningomyelocele, Arnold-Chiari malformation, and hydrocephalus. We report a patient with bilateral vocal cord palsy associated with the lobar form of holoprosencephaly. In this case, bilateral vocal cord palsy was caused by the disruption of the cortical laryngeal motoneurons. Neonatal stridor must be carefully evaluated by the neonatologist to exclude severe cerebral anomalies. (J Child Neurol 2001;16:932-934).
