目的 探讨颅底肿瘤的显微手术治疗方法。方法 总结86例颅底肿瘤的临床表现、影像学特征及显微手术治疗的经验。结果 肿瘤全切除69例，次全切除11例，部分切除4例，死亡2例；术前颅神经功能损伤64例72条，术后恢复38条，好转11条，症状无改善14条，加重9条，新颅神经损伤7条。结论 显微手术切除颅底肿瘤是更为安全和有效的治疗方法；熟练的显微外科技术和技巧，是提高肿瘤全切除率，降低手术病死率和颅神经损伤率的关键。

The clinical analysis of 86 cases of basicranial tumours treated by microsurgery

Objective To probe into the treatment of basicranial tumors by microsurgery.Methods The clinical manifestation,image characteristics and the microsurgery experience of 86 cases of basicranial tumours were summed up.Results The total,sub total,and partial resection were carried out in 69,11 and 4 cases respectively.2 cases died,Among 64 cases 72 pieces of cranial nerves were injured before operation,the function of injured cranial nerves recovered in 38 pieces,bettered in 11 pieces,hardly improved in 14 pieces and worsened in 9 pieces after operation,and the new injury of cranial nerves occured in 7 pieces.Conclusion Microsurgery was a safer and more effective approach to resect the basicranial tumors,skilled microsurgery techniques,familiar with basicranial micro anatomy are the key to enhancing the total tumor resection rate,reduce the operation death rate and the injury of cranial nerves.
