We have used navigation system during surgery for head and neck region in 62 cases including 35 anterior skull base surgeries and 18 lateral skull base surgeries since September 2000 to August 2007. Navigation system was very useful in almost all anterior skull base surgeries and some of lateral skull base surgeries, especially when the lesion was adjacent to important organs (eye ball, optic nerve and internal carotid artery etc.) and liable to bleed. It was also very useful in case of volume reduction surgery for fibrous dysplasia of facial skull.
The necessity of navigation system didn't match the difficulty of surgery evaluated by Gaihoren in the report titled “Gaihoren's tentative plan concerning the remuneration for surgery (6th edition)” in otolaryngology, head and neck region.
