[Fronto-temporo-orbito-zygomatic approach - analysis of the surgical technique on cadaver simulations].

This paper presents consecutive stages of the fronto-temporo-orbito-zygomatic approach (FTOZA). Two simulations of FTOZA were performed on non-fixed human cadavers without any known pathologies in the head and neck. The consecutive stages of the procedure were documented with photographs and schematic diagrams. The starting point for FTOZA is a pterional craniotomy and osteotomy including the orbital rim, body of the zygomatic bone and zygomatic arch. In justified cases it is also possible to temporarily remove the upper and lateral walls of the orbit. Wide drawing apart of the Sylvian fissure is an important supplement of the approach. The fronto-temporo-orbito-zygomatic approach is a reproducible technique, which provides surgical penetration of the middle cranial fossa and related regions. This approach is particularly useful in the treatment of tumours of the above-mentioned anatomical areas as well as vascular malformation of the posterior part of the arterial circle of the brain.
