Clinical anatomy of trigeminal nerve root was investigated on 51 cadaver human skull base specimen. 102 parameters of trigeminal nerve roots were analyzed. All specimens were divided into 3 groups for definition of age-related changes: < 40 years, between 41 and 50 years, > 50 years. We demonstrated that mean length and diameter of trigeminal nerve root did not change with age. Trigeminal nerve root entry zone is located inside pioarachnoidal infundibulum--subpial cavity. We found that pioarachnoidal infundibulum was prone to age-related involutive changes.
