In this study, the mobilization of all cranial nerves with drilling of several bony structure,cutting of ligaments, folds and dural attachments were performed via different skull baseapproaches.Twenty cadaveric head specimens filled with microfil were dissected bilaterally. On 5 dryskulls, important bony structures were also studied.We observed that the mobilization of the nerves II, III, VI, VIII, and XII were not easycomparing to other cranial nerves. The subfrontal parenchymal tissue should be removedand the olfactory nerve should be dissected for mobilization of the first cranial nerve. Themobilization of the nerves IV, V, VII, IX, and XI were dramatically remarkable after drillingof superior orbital fissure, foramen ovale, foramen rotundum, Fallopian canal, and jugularforamen.
