Topographic anatomy of the trigeminal nerve root in the lateral cistern of the pons varolii
51 sectional preparation of the skull base were used to study the clinical anatomy of the trigeminal nerve root. Analyzed were the anatomical parameters of 102 roots of the trigeminal nerve. In order to identify age-related changes in the root entry zone into the brain stem all the preparations were divided into 3 age groups: up to 40 years, from 41 to 50 years, 51 years of age and older. Established was the fact that the average length and diameter of the root of the trigeminal nerve does not change, however the piaarachnoidal funnel is subject to age involutive changes.
