PRACTICAL APPLICATION OF 3D-CT AND THREE-DIMENSIONAL SKULL MODEL IN THE TRIGEMINAL NEURINOMA OF THE SKULL BASE

Abstract

　Three-dimensional imaging (3D-CT) and virtual reality temporal bone simulator would provide accurate anatomical information to perform skull base surgery and useful for preoperative surgical planning and simulation operation.

　We presented a case of trigeminal neurinoma of the parapharyngeal space that involved the middle of the skull base.
　The tumor was resected by the Combination of Orbito-zygomatic approach with transcervical approach, which preserves the facial nerves. This is a useful procedure for accessing to infratemporal fossa or parapharygeal space.
