The authors devised their own craniometric method of determining the normal position of the venous angle on the lateral phlebogram. The fundamental principles of the method are as follows: (1) two auxiliary lines; i.e. (a) a horizontal line the nasion - the tuberculum sellae (N-TS); (b)a diagonal line the nasion - the tabula interna (N-Ti); (2) the two auxiliary lines form the angle alpha, which is equal to 20.44+/- 4.2 degree; (3) the proportional position of the venous angle (the point of intersection S on the diagonal N-Ti) is the ratio of the distance N-S to the total length of the diagonal N-Ti,i.e.: (formula: see text). The value is equal to 49.8 +/- 4.6%. The present method takes into consideration both the length and the height of the skull, has a small statistical dispersion and is simpler than the other available methods.
