[Extended subfrontal approach to the central cranial base - analysis of the surgical technique in cadaver simulation].
The aim of the study was to present consecutive stages of the extended subfrontal approach (ESA). Eight simulations of ESA 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 ESA is a bifrontal craniotomy and osteotomy including the base of the nose and superior parts of the orbits. If the anterior cranial base is not invaded by the tumour, an attempt to partially preserve olfaction is possible. Wound closure after removal of the tumour with ESA requires reconstruction of the tissue barrier between the cranial cavity, paranasal sinuses and nasopharynx. The extended subfrontal approach is a reproducible technique which provides surgical penetration of the central skull base. This approach is particularly useful in the surgical treatment of tumours expanding along the midline, superiorly and inferiorly to the skull base.
