对骑跨颅中、后窝肿瘤,手术入路选择是否合理、术野暴露是否合适意义重大,显露过分和显露不足均不可取。常用的经典入路有:颞下经小脑幕入路(硬脑膜外或硬脑膜下)、乙状窦前入路、枕下乙状窦后入路和幕上下联合入路(硬脑膜外或硬脑膜下)等。目前,国内外已探索出一些新入路,其中部分入路是对经典入路的变异和改良。本文就骑跨颅中、后窝肿瘤的经典入路和新入路以及一些新技术新仪器在临床上的应用进行综述。
Riding across the skull, posterior fossa tumors, the choice of surgical approach is reasonable, operative exposure is significant and significant, revealing too much and revealing inadequate are undesirable. Commonly used classic approach are: infratemporal transmucocele approach (extradural or subdural), sigmoid anterior approach, suboccipital sigmoid sinus posterior approach and supratentorial approach (epidural or Subdural) and so on. At present, some new approaches have been explored at home and abroad, some of which are variations and improvements to the classic approach. This article reviews the classic approach and new approach of riding across cranial and posterior fossa tumors and the clinical application of some new technologies and instruments.
