anomaly of Chiari, syringomyelia, posterior cranial fossa


The aim of this research — studying of correlation between posterior cranial fossa size and degree of cerebellar tonsils displacement, size of cyrix cysts, and speed of disease progression.
The research is based on diagnostic data analysis before and after surgery at 120 patients with Chiari malformation, liquor circulation disorders on craniovertebral level, with or without syringomyelia.
Received data suggest that the smaller size of the posterior cranial fossa is, the degree of cerebellar tonsils dislocation is greater, cyrix cysts are larger and disease duration is less before surgical treatment performing.
