[Anatomical peculiarities of transcranial approach to the orbital cavity].
The purpose of this work was to study the anatomical features of transcranial approach to the cranioorbital area and the orbital cavity. The preparation of 32 orbits obtained from 16 human cadavers fixed in formalin, was performed. In the anatomical study, typical fronto-temporal extradural approach to the anterior cranial fossa was used, together with the micropreparation of the orbital structures from 3 intermuscular approaches. It was demonstrated that at different stages of transcranial approach, its parameters were mainly influenced by either craniometric indices, or anatomical peculiarities of orbital nerves and vessels position. The data obtained allow to plan the surgical intervention on the basis of results of radiological study and the data on frequency of various anatomical variants of an arrangement of ophthalmic artery branches.
