Chekanova I. Individual anatomical variability of the middle cranial fossa of a mature person.

Researchers pay the most attention to the bone structures of the skull base, and especially the middle cranial fossa. This is due to the very complex bone architecture and the importance of the vascular and nervous structures located in this area. Recently, the middle cranial fossa is becoming an increasingly interesting area for neurosurgeons, due to the development of a number of modern surgical interventions. For the first time a comprehensive study of the structure, shape, position and asymmetry of the middle cranial fossa depending on sex and craniotype from the standpoint of the study of individual anatomical variability not only on bone preparations but also on craniotomograms of the adult head. New devices and techniques have been developed and proposed for detailed and ultra-precise craniometric analysis of deep anatomical structures of the head, especially the middle cranial fossa. For the first time, the range of variability of linear parameters of the middle cranial fossa at different levels and on both sides was established. For the first time the range of variability of the cranial index was established, which was confirmed by statistical indicators of the linear size of the skull and this main index of the head according to the teachings of Academician V.M. Shevkunenko. For the first time the existing ranges of variability of the main craniotopographic lines of the inner base of the skull were established with the definition of their correlations with each other and with the longitudinal parameters of the middle cranial fossa.
