Endoscopic endonasal cavernous sinus visa transsphenoidal aporoach:an anatomic study

[Objective] To explore the approach of endoscopic endonasal cavernous sinus visa transsphenoidal, and establish the anatomic basis for endoscopic endonasal treatment. [Methods] Twelve adult cadaveric heads were anatomied visa transsphenoidal by using endoscopy, and the internal carotid artery, anatomic cranial nerves parameters were measured. [Results] The cavemous sinus could be exposed clearly by using endoscopy. The internal carotid artery, oculomotor, trochlera, abducent and optic nerves could be separated completely. [Conclusion] The approach of exposing cavemous sinus visa transsphenoidal by using endoscopic endonasal is simple, minimally invasive, and useful for clinic operation.
