Abstract: OBJECTIVE To study the anatomic relationship of the divus region and provide the anatomical basis for the extended endoscopic endonasal approach to clivus region.METHODS 10 cadaveric heads were dissected using the surgical microscope and endoscope.RESULTS 1.With the extended endoscopic endonasal approach,we can expose the ventral side of brain stem from interpeduncal fossa to the foramen magnum and upper,middle,and lower neurovascular complexes.2.The clivus region,formed by the sphenoid body and the clival part of occipital bone,is situated between the dorsum sellae and the anterior margin of the foramen magnum.Occipital bone and the petrous part of the temporal bone were separated by the petroclival fissure.CONCLUSION 1.The extended endoscopic endonasal approach can be tailored to deal with the local lesions involving the clivus and adjacent posterior cranial fossa structures.2.Full andcomprehensive understanding of the anatomy around the clivus region can help surgeons to improve accuracy and safety of procedures in this region.
