Abstract
We report here our method of the image-guided surgery for middle cranial fossa approach. We applied a volume sampling to the patients who had been scheduled to suffer middle cranial fossa approach for removal of the acoustic neuroma or vestibular nerve section using a helical CT and re-construct three-dimensional images. After obtaining three-dimensional images, we modified those images and obtain surgical-view image that indicated the position of the internal auditory canal and superior semicircular canal. Referring to the images, we drilled to open the internal auditory canal and these images were thought to be useful. Clinical applications of three-dimensional images heve been variously reported. Our image-guided surgery for the middle cranial fossa approach is thought to be one of the beneficial method.
