THE PETROSAL (PRESIGMOID transtentorial) approach has been advocated for resecting retrochiasmatic craniopharyngiomas. The projection of the surgical corridor, posterior to anterior and inferior upward, is particularly valuable in dissecting the upper pole of the tumor, which projects high into the third ventricle. This approach allows direct visualization for dissecting the hypothalamus and the pituitary stalk, and maintaining their blood supply and functional integrity. With a web site video presentation, we demonstrate the operative nuances of the approach to these tumors. We recommend this approach for patients with large and giant retrochiasmatic craniopharyngiomas.
岩骨（乙状窦前经小脑幕）入路已被推荐用于切除视交叉后颅咽管瘤。手术通道从前向后、从下向上的投影，在解剖肿瘤向上延伸至第三脑室的上极时特别有价值。这种入路允许直接观察以解剖下丘脑和垂体柄，并维持它们的血供和功能完整性。通过一个网站视频演示，我们展示了该入路治疗这些肿瘤的手术细节。我们推荐将这种入路用于患有大型和巨大型视交叉后颅咽管瘤的患者。
