摘　　要：经不同手术入路应用显微外科技术切除鞍区脑膜瘤３５例。按术中是否需要脑牵拉与脑组织的直观反应，将手术显露程度分四级。Ⅰ级：肿瘤自然显露，毋须脑牵拉便将肿瘤切除１２例，占３４．３％；Ⅱ级：对脑间断性略加牵拉，去牵拉后，局部外观与未牵拉部无异１７例，占４８．６％；Ⅲ级：牵拉处脑组织有伤痕３例，占８．６％；Ⅳ好：脑损伤较明显或呈不同程度的肿胀３例，占８．６％。全组Ⅱ～Ⅰ级显露２９例，占８２．９％，以经眶颧额颞下入路切除鞍旁脑膜瘤时最多见。本显露程度分级可作为衡量颅底肿瘤手术方法是否合理的一项指标。he surgical exposures were classified as 4 grades according to the observations of op-erations on 35 patients with parasellar or suprasellar meningiomas. Grade Ⅰ(n=12):it wasunnecessary to retract brain tissue during removal of the tumors,Grade Ⅱ(n=17):withavery little cerebral retraction, but no damage to the brain was found by the naked eye aftertumor removal.GradeⅢ (n=3):local slight injury was brought to the brain surface beneaththe self-retractor.Grade Ⅳ (n=3):it was found to have obvious brain damage or cerebralswelling of different degrees,owing to brain retraction or disturbance of brain venousdrainage The exposures graded Ⅱ to Ⅰ mostly happened in the patients with parasellarmeningiomas operated on via a combined frontotemporal-orbitozygomatic approach.Theauthors believe that this classification may be used as one of the indexes for evaluating therationalities of some operative approaches in skull base surgery.
