Respiratory obstruction and apnea in infants with bilateral abductor vocal cord paralysis, meningomyelocele, hydrocephalus, and Arnold-Chiari malformation.
This report describes 21 infants and children with bilateral abductor vocal cord paralysis and associated meningomyelocele, Arnold-Chiari malformation, and hydrocephalus. Two life-threatening forms of respiratory distress are distinguished: (1) upper airway obstruction due to bilateral abductor cord paralysis and (2) apnea. Clinically significant episodes of apnea were documented in 13 infants. Ten infants had evidence of aspiration and dysphagia. Vocal cord paralysis, apnea, aspiration, and dysphagia were frequently temporally related to increased intracranial pressure.
