成人垂体窝与蝶窦仅隔以薄层骨板,Schloffer(1907)根据这一解剖特点,对蝶鞍肿瘤采用了经蝶骨途径的手术方法,由于手术野深而狭小,难于操作.Guiot(1958)改进这一技术,即用放射荧光镜结合手术显微镜给予强光和放大,便增加了手术的安全性.但施行该手术时有可能忘记颈内动脉和视神经可以突入蝶窦,可仅复以薄层或不完整骨壳.Renn等发现少数病例仅隔以一层粘膜和硬脑膜.本
According to this anatomical feature, Schloffer (1907) adopted a trans-orbital approach to sella pituitary tumors in adult pituitary glands and sphenoid sinus. Because of the deep and narrow surgical field, 1958) to improve the technology, that is, with fluorescence fluoroscopy combined with surgical microscope to give light and amplification, increased surgical safety.However, the implementation of the operation may forget the internal carotid artery and optic nerve can enter the sphenoid sinus, can only complex With thin or incomplete bone shell, Renn found that a few cases separated by a layer of mucosa and dura.
