ABSTRACT
The authors proposed to use a lumbar part of calf carcass as a new biological model for training of basic practical skills in order to perform the neurosurgical operative interventions on the spine. The proximity of anatomico-surgical parameters of given model and human cavader lumbar spine was estimated. The study proved the possibility of use of lumbar part of calf carcass for training techniques of transpedicular fixation and microdiskectomy in lumbar part.

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.

Almost 90 years has passed from the moment of the development of transcranial approach to the cranio-orbital area and orbital cavity. But the application of the method was limited due to using mainly extracranial approaches. The authors have analyzed results of studying the parameters of transcranial approach to 32 orbits of 16 corpses of adult subjects, and results of treatment of 24 patients with neoplasms of the cranio-orbital area and orbit, operated by transcranial approach. The indications to different modifications of the approach and to each of the intermuscular approaches to the orbital nerve were established.
