Objective To provivide the anatomic data for the neurosurgery through subtemporal transtentorial approach to the superior petroclival region. Methods The neurosuvgery through subtemporal transtentorid approach to the superior petroclival regions was simulated in 10 (20 sides) formalin-fixed cadaveric adult heads,where the arteries were infused into with colored emulsion.The anatomy related to the neursurgery through the subtemperal transtentorial approach to the superior petroclival regions,including run and distribution of the vessels and nerves,relationship among the vessels,nerves and adjacent stnlcture,were observed and measured.Results There were microstructures such Labble veins, posterior cerebral arteries, oculomotor nerves, trochlear nerves, and superior cerebellar arteries and so on in the superior petroclival regions. The distance from the point where the trochlear nerve entered into the edge of the tentorium to the oculomotor nerve was [5.50±1.82(4.24-6.98)]mm.The length of the branches of Labble vein was (9.56±4.06)～(14.78±4.6O)mm. Conclusions The subtemporal.transtentorial approach is adapted to the exposure of the superior petroclival region,The present results are helpful to the increase in the safety and successful rate of the neurosurgery in the superior petroclival region.
