Abstract
We present a 52-year-old male case of right trigeminal neurinoma at lateral cavernous
sinus. The tumor was 40 mm in maximum diameter, obviously compressed temporal lobe
and encased internal carotid artery. Extradural middle fossa and transcavernous approach
was applied and the tumor was resected via Parkinson's triangle. This approach enabled
safe and effective tumor resection, sufficient visualization, and operative field
([Figs. 1] and [2]). We performed dissection of the tumor from trigeminal nerve, tentorium, and middle
fossa and resect the tumor around internal carotid artery sufficiently. Postoperative
course was good without any new neurological deficit. This surgical method is considered
safe and effective for the resection of the tumor at lateral cavernous sinus.
