Resection of a pineal tumour requires fastidious pre-operative planning to select the optimal surgical approach and maximise resection while minimising morbidity.
To describe and compare the supracerebellar infratentorial and occipital transtentorial approaches.
Specific considerations include patient-specific anatomy, extent and relationships of the tumour, and the techniques likely to be employed during resection. The supracerebellar infratentorial approach provides a direct corridor to pineal tumours caudal to the deep veins; for tumours invaginating the tectal plate in a caudal direction the occipital transtentorial provides a better view.
松果体肿瘤的切除需要精心的术前规划，以选择最佳的手术入路，最大限度地切除肿瘤，同时最大限度地降低发病率。
描述并比较幕上小脑下和枕下经天幕入路。
具体考虑因素包括患者特定的解剖结构、肿瘤的范围和与肿瘤的关系，以及在切除过程中可能采用的技术。幕上小脑下入路为位于深静脉后方的松果体肿瘤提供了直接的通道；对于向尾部方向内卷的肿瘤，枕下经天幕入路提供了更好的视野。
