Aim. To identify the combined variability of the anterior cranial fossa with orbital forms in flexi- and platybasilar craniotypes. Material and Methods. On 100 skulls of adults the method of craniotopometry to study the shape of the anterior cranial fossa according to the magnitude of the longitudinally transverse index, the shape of the orbit by the orbital index. Results and Discussion. In flexibasilar craniotypes, the broad shape of the anterior cranial fossa is combined with medium-high (64.2%) and medium deep (42.9%), low (21.4%), shallow (35.7%), high (14.3%) and deep (21.4%) orbital forms; mid-wide fovea is combined with medium-high (80%), shallow (60%), high, low (10%), deep, middle-deep (20%); a narrow shape of the fossa in 100% of cases - with medium-high, deep, medium-deep (50%). In platybasilar craniotypes the wide form of the fossa is combined with medium-high (64.3%) and medium-deep (42.9%), shallow (35.7%), low (21.4%), deep (21.4%), high (14.3%); medium-wide fossa is combined with medium-high (80%) and shallow orbit (60%), deep (20%), high (10%), medium-deep (20%), low (10%); the narrow shape of the fovea is 100% combined with medium-high and medium-deep (50%), deep (50%) forms of the orbit. Conclusions. The results of the study are an indispensable theoretical basis for developing the tactic of the stereotactic transorbital approach to the pathological processes of the anterior cranial fossa.
