Bilateral vocal cord paralysis in newborns with neuraxial malformations--two case reports--.

Two neonates presented with inspiratory stridor due to bilateral vocal cord paralysis associated with occipital encephalocele, Chiari malformation, and hydrocephalus in one patient, and cervical meningomyelocele and Chiari malformation in the other patient. The clinical symptoms dramatically regressed after repair of the encephalocele or meningomyelocele with no requirement for craniovertebral decompressive procedures or shunts in the acute phase. Careful evaluation of neonatal stridor and recognition of vocal cord paralysis are important, as treatment of associated congenital central nervous system anomalies is likely to achieve satisfactory surgical results.
