Eighteen consecutive patients with olfactory groove meningiomas, with diameters ranging from 1.5 to 7 cm, underwent microsurgical tumour resection using a unilateral frontal interhemispheric approach. Unilateral frontal craniotomy, superior to the frontal sinus, exposing the superior sagittal sinus was performed. The ipsilateral frontal lobe was gently retracted laterally, and the tumour resected through the gap between the falx and the medial aspect of the frontal lobe, anteriorly to the genu of the corpus callosum. Gross total tumour resection was achieved in all the patients. There was no evidence of damage to the frontal lobes, the anterior cerebral arteries or the optic system. Compared with the more commonly applied subfrontal route, the interhemispheric approach has the advantages of sparing the frontal sinuses and providing excellent overview of the dissection of the anterior cerebral arteries and the optic system, as well as for the resection of tumour invading the frontal cranial base.
18例连续的嗅沟脑膜瘤患者，肿瘤直径为1.5至7厘米，采用单侧额部经半球间入路进行显微手术肿瘤切除。在额窦上方进行单侧额骨开颅术，暴露上矢状窦。同侧额叶轻轻向外牵拉，通过大脑镰与额叶内侧之间、胼胝体膝部前方的间隙切除肿瘤。所有患者均实现了肿瘤全切除。未发现额叶、大脑前动脉或视系统受损的证据。与更常用的额下入路相比，经半球间入路具有保留额窦的优点，并且能很好地观察大脑前动脉和视系统的解剖情况，以及用于切除侵犯额颅底的肿瘤。
