ABSTRACT
Objective To study the microsurgical anatomy of the extended transsphenoidal approach to the central skull base, and provide anatomical parameters for the surgical approach. Methods Forty wet skulls were dissected in detail via mimic extended transsphenoidal approaches under an operating microscope and an extended exposed operating microscope. Important structures and connections were observed, measured precisely and photographed. Dry skulls were used to observe and measure the osseous structures related to the approaches. Results The extended transsphenoidal approach can expand ahead, astern and laterally to the suprasellar intradural space by resecting bone and displaying the basafrontal lobe, pre-chaismatic space, optic chiasma cistern, anterior cerebral artery complex, the branches and cavernous sinus segment of the internal carotid artery, pons, basilar artery and its branches, posterior cerebral artery, and superior cerebellar artery. Conclusion The extended transsphenoidal approach can provide the new pathway for treating lesions of the central skull base.
