鞍区病变种类繁多,因其解剖部位深在,周围毗邻重要神经、血管,尤其与视神经、垂体、颈内动脉、丘脑等结构关系非常密切,手术风险大,术后并发症较多。前纵裂入路利用自然脑裂的分离,无需牵拉额叶就可直接暴露重要血管、神经及双侧海绵窦内侧壁等周围结构,尤其能充分暴露第四间隙,手术视野清楚、操作角度好、盲区少,肿瘤全切率高,疗效满意,尤适用于切除鞍内向鞍上、第三脑室前部、蝶窦发展的肿瘤。目前应用较为广泛,随着显微神经外科技术及器械的发展,该手术入路日趋成熟。
Saddle area lesions a wide range of deep anatomic parts, adjacent to the surrounding important nerves, blood vessels, especially with the optic nerve, pituitary, internal carotid artery, thalamus and other structures are very close, the risk of surgery, postoperative complications more. The use of the former longitudinal split the use of natural schizonts of the separation, without the need to pull the frontal lobes can be directly exposed important blood vessels, nerves and bilateral cavernous sinus and other peripheral structures, especially to fully expose the fourth gap, the surgical field of vision clear, the operating point of view Good, less blind, high rate of tumor resection, satisfactory results, especially for the removal of saddle on the saddle, the front of the third ventricle, sphenoid sinus tumor. Currently more widely used, with the development of microsurgery technology and equipment, the operation of the increasingly mature.
