对于每一位神经外科医师来说,翼点入路(pterional approach)大概都是启蒙级入路吧。然而,除了翼点的定义(图0)和罗列的一条条手术适应症和手术步骤外,对于这个几乎万能的幕上入路的“前世今生”,各大教科书似乎都很少涉及。个人觉得,对一个入路的学习,应该包括其发展和演变;了解它的历史,才能更好地掌握现状和构想未来。今天,就来简单罗列一下翼点入路的编年史。

小结
从上面的演变过程就可以看出,如今的翼点入路是由最初的额下入路移向侧方而来的,经Yasargil的完善,翼点入路如今的标准,应包括额颞开颅、蝶骨嵴的磨除、侧裂的开放。在此基础上,为处理更深的颅底区域,翼点入路存在着不同的扩展,如结合颞下入路扩展侧方视野;附加切除眶颧扩展上方视野;结合前床突的磨除彻底开放海绵窦。另一种相反的趋势则是继续做小,这也体现了历史的趋势。另外,经侧裂还有其他的扩展术式,如经侧裂行选择性杏仁海马切除术等,这里尚未涉及。因此,翼点入路是神经外科医师最基本也是最重要的武器,是学习其他入路的基础。
