23 - Intradural V4 segment of the VA

3D Model

This is a 3D models combined from macrophotography and micro 3D model of the CP (cerebellopontine angle) generated from microscope images. The craniotomy was extended to the mastoid emissary vein. The dura was opened and the vertebral artery V4 (intradural segment) is presented. The anatomy of the cerebellopontine angle is presented. The nerves - IX, X, XI entering the jugular foramen are presented. The VII/VIII nerve complex entering the IAC (internal accoustic canal) are visualised. The Tuebingen line is indicated as a mark of the position of the IAC.
