三脑室颅咽管瘤和前交通动脉瘤的传统手术入路难度大,易损伤嗅神经和桥静脉。本文介绍了一种保留桥静脉和嗅神经的新手术入路。 手术入路:发际内冠状切开头皮,向下显露额骨至鼻根部并保护眶上神经。于额骨的中心基底部取四个正中旁钻孔,上对在鼻根上方5cm,下对在眉间外上方。切除颅骨的范围几乎包括整个额窦,仅剩内板的下部。冲洗术野及更换可能污染的器械。用咬骨钳和气钻切除鸡冠和额窦内板,将大脑廉基底部分 Third ventricle craniopharyngioma and anterior communicating artery aneurysm traditional surgery difficult, easy to damage the olfactory nerve and the bridge vein. This article describes a new approach to preserving the bridging veins and the olfactory nerve. Surgical approach: the incision of the scalp in the hairline, exposing the frontal bone to the nasal root and protecting the supraorbital nerve. In the frontal base of the frontal bone to take four median drilling, on the top of the nose 5cm, the next on the top outside the eyebrows. Excision of the skull range includes almost the entire frontal sinus, leaving only the lower part of the inner plate. Rinse the surgical field and replace possible contaminated equipment. Use rongeur and air drill to cut the crest and frontal sinus plate, the brain of the base part of the inexpensive
