[Laryngo-pharyngeal paralysis. Complications during the course of myelomeningoceles].

Report of 5 cases in babies with myèlomeningocele and hydrocephalus stridor and troubles in swallowing appeared after a free interval. These facts were already reported in literature. They represent an impairment of cranial nerves (IX,X and XI). The lesion may be located at the level of the nerves themselves or at the level of the origin nucleus in the brain stem. The mechanism of the lesion is not well known. The role of intracranial hypertension and of Arnold-Chiari malformation seem to be prominent.
