巨大前颅底脑膜瘤直径常在6cm以上,大致位于中线,前起于鸡冠前方,后达鞍结节,下常侵袭筛板和蝶骨平台,上达大脑镰游离缘上方。传统上经双侧额底入路手术切除,需要取双侧额瓣、两侧额部硬脑膜切开、切断并牵开上矢状窦,创伤较大。作者近来改良这种做法,仅取右侧额下入路全切除肿瘤,疗效不亚于传统做法。现进行报道并分析。 Huge anterior skull base meningioma diameter often more than 6cm, roughly in the midline, before the front of the crest, after the saddle nodules, often under attack sieve plate and sphenoid platform, up to the falx margin above the falx. Traditionally by the bilateral approach at the bottom of the surgical resection, need to take bilateral flap, both sides of the frontal dura incision, cut off and pull the sagittal sinus, trauma. The author recently improved this practice, just take the right inferior frontal resection of the tumor, the efficacy of no less than the traditional approach. Now report and analyze.
