Abstract:
A growing number of children and adolescents are being diagnosed as Chiari malformation type Ⅰ (CM-Ⅰ) for behavioral disorders,developmental delay,seizures,or abnormal orpharyngeal function.The aim of this study was to compare the clinical characteristics,imaging findings and surgical outcomes of CM-Ⅰ in pediatric and adult patients.Between January 2014 and June 2017,84 patients with CM-Ⅰ underwent surgical treatment in our department.We divided the patients into two groups:pediatric group (n=1 1,age <18 years)and adult group (n=73,age ≥18 years).Data on clinical characteristics,imaging findings,surgical outcomes,and prognosis were retrospectively reviewed and compared between these two groups.For clinical presentation,scoliosis (36.4%) and developmental delay (36.4%) were more common in pediatric patients,whereas,sensory disturbance (58.9%) and motor weakness (41.1%) were more common in adult patients.Imaging findings showed that the incidence of hydrocephalus and craniovertebral junctional abnormalities was significantly higher in pediatric group than in adult group (P<0.05).Compared to adult group,pediatric group showed a better improvement or resolution of syrinx and tonsillar herniation after surgical treatments (P<0.05).The total Chicago Chiari Outcome Scale (CCOS) score in pediatric patients at the last follow-up was significantly higher than that in adult patients (P=0.002).In conclusion,the clinical characteristics and imaging findings appeared to be different in pediatric and adult patients with CM-Ⅰ.The surgical outcomes of pediatric patients were shown to be significantly better than those of adult patients.
