Abstract：Objective To investigate the microscopic anatomy study of surgical approach into the third ventricle through the cho-roid fissure and to provide the theoretical basis for minimizing normal brain tissue damage. Methods 8 cases of Chinese adult moist skull specimens were fixed with 10% formalin, and each arterial and venous system were poured with red and blue dye latex. The cho-roid fissure part of lateral ventricle in specimen was dissected and observed layer by layer according to the surgical approach by using 4-10 time zoom surgical microscope. Results Choroid fissure was an inverted “C” shape between the dome and the hypothalamus, and it can be divided into (1) The body:located in the body of lateral cerebral ventricle between the upper margin of the thalamus and the dome body. (2) Triangular part:in the triangle area in the lateral ventricles between the pulvinar and dome foot. (3) Temporal:in the temporal horn of the lateral ventricle between the surface and the dome umbrella hypothalamus. Conclusion Surgical approach through choroid fissure into the third ventricle, the central pool and medial temporal lobe lesions bears the advantage of wider operative horizon, less surgical injury and so on.
