Late results of surgical treatment of tumors of the posterior cranial fossa in children

: The work is based on the analysis of the course followed by the disease in 533 patients aged 18 months to 15 years who underwent operation for benign and malignant tumors of the cerebellum and fourth ventricle in the period between 1964 and 1975. The late results were appraised in 1980-1981 in 269 patients. The minimum follow-up period of the surviving patients is 5 years, the maximum period 16 years. Catamnestic study showed that among all tumors of the posterior cranial fossa in children, only cerebellar astrocytoma and chorioidpapilloma were marked by a favourable late prognosis. Total sparing removal of these tumors leads to practical recovery of most patients.
