摘　　要：目的探讨鞍上脑膜瘤经前纵裂入路切除的价值及效果。方法 29例经MRI检查及术后病理检查确诊为鞍上脑膜瘤患者,瘤体最大直径3～6 cm,采用小骨窗(约4 cm×5 cm)经前纵裂入路显微手术切除。结果肿瘤全切除25例(86%)(SimpsonⅠ、Ⅱ),次全切除4例。视力视野改善者19例。术后尿崩症2例,电解质紊乱1例,无手术死亡。结论鞍区脑膜瘤向前方、上方、鞍内生长者,采用小骨窗经前纵裂入路能较好显露瘤体,脑组织牵拉轻,并发症发生率低,显著提高肿瘤的全切除率。Objective To investigate the effect of surgical resection of suprasella meningioma via anterior interhemispheric approach.Methods A total of 29 patients with suprasella meningioma（diameter was 3~6 cm） confirmed by MRI scan and postoperative pathological examination were included in the study.All cases were treated by small craniotomy（4 cm×5 cm） via anterior interhenispheric approach.Results Total removal（Simpson Ⅰ,Ⅱ） was achieved in 25 cases（86%） and subtotal removal in 4 cases.Visual impairment improved in 19 cases.There were 2 cases of diabetes insipidus and 1 case of electrolyte disturbance.No dead case occurred.Conclusion Suprasella meningiomas that grow anteriorly,superiorly or within the sella can be well exposed by small craniotomy through anterior interhemispheric approach,which increases the total removal rate with minimal invasiveness to brain tissues and less complications.
