Abstract： 目的探讨内镜辅助眶上锁孔入路治疗垂体瘤的可行性.方法21例福尔马林固定尸体头部标本用于鞍区各解剖结构,特别是垂体柄、视神经、视交叉及其供血动脉特点的观察,总结手术可利用的间隙、应保护的结构;在9例新鲜尸头上模拟进行内镜辅助眶上锁孔入路手术,进一步验证其可行性及优势.结果颈内动脉床突上段长度14.5±1.3mm(8.1～18.5mm),发向垂体柄、视神经或视交叉的穿支动脉的支数分别为:大脑前或前交通动脉3.0支(2～6支),颈内动脉2.1支(1～5支),后交通动脉3.2支(3～6支),基底动脉1.4支(1～3支).视神经颅内段长度为11.4±2.7mm(6.1～17.6mm),第1间隙面积为44.8±3.4mm2(7.0～100.8mm2),手术可通过第1间隙或(和)第2间隙进行.结论通过眶上锁孔入路治疗向鞍上发展的垂体瘤有充足的操作空间,具有视神经、视交叉减压充分,利于保护其供血动脉的优点.
