The authors report 17 cases of symptomatic Chiari type II malformation occurring in two distinct age dependent population. In Group I, 13 neonates and infants in the first year of life presented with cranial nerve and brain stem dysfunction characterized by vocal cord paralysis, apnea, dysphagia and laryngeal stridor. In Group II, 4 patients developed signs and symptoms after the first year of life. In this group, the presentation was more insidious and included neck pain and cerebellar manifestations. The surgical treatment consisted initially in shunt implantation or revision and when there was no improvement, posterior fossa decompression was performed.

The authors report 17 cases of symptomatic Chiari type II malformation occurring in two distinct age dependent population. In Group I, 13 neonates and infants in the first year of life presented with cranial nerve and brain stem dysfunction characterized by vocal cord paralysis, apnea, dysphagia and laryngeal stridor. In Group II, 4 patients developed signs and symptoms after the first year of life.
In this group, the presentation was more insidious and included neck pain and cerebellar manifestations. The surgical treatment consisted initially in shunt implantation or revision and when there was no improvement, posterior fossa decompression was performed.
The response to the surgical treatment differed considerably between the two groups: older patients improved promptly after surgery and there was no casualties; in newborn and infants, especially those under 6 months of age, the mortality rate was The authors stress that prompt diagnosis and surgical intervention should be performed in order to produce a favorable outcome.
Os pacientes foram divididos em Grupos I idade inferior a 12 meses e Grupo II idade superior a 12 meses. Do total, 11 eram do sexo feminino e 6 do sexo masculino. Nos previamente derivados, a primeira medida foi certificar-se que o sistema funcionava adequadamente.
Em todos os 3 houve ventriculite precedendo o quadro. Uma paciente encontra-se clinica e neurologicamente estabilizada, apesar de traqueostomizada. Cochrane et al. Vandertop et al. Dahl et al.
