前颅底巨大脑膜瘤的锁孔手术

Resection the Huge Intracranial Meningioma Located in the Frontal Skull by Keyhole Operation

目的探讨锁孔神经外科手术治疗前颅底脑膜瘤的手术技巧和适应证。方法对39例前颅底巨大脑膜瘤行眉弓上锁孔开颅,显微神经外科手术切除。结果39例全部切除,无手术死亡、致残及相关并发症。结论锁孔手术是治疗前颅底肿瘤的微创治疗技术,减少了手术创伤及并发症的发生,恰当选择适应证、充分的术前准备和显微外科技术是手术的关键。

Objective To study the surgical techniques with keyhole operation for treatment of the huge intracranial meningioma located in the frontal skull. Methods 39 cases of huge intracranial meningioma were removed by microsurgery with supra - eyebrow approach keyhole operation. Results 39 cases of meningioma were totally removed. There was no associated morbidity,mortality or exacebation in all cases. Conclusion It suggests that keyhole microsurgery may provide maximum efficiency to remove the huge intracranial tumor located in the frontal skull and minimum invasiveness. However,it is very important to choose indication properly,to prepare suffieienctly before operation,and to operate with proficient skill of microsurgery.
