摘要

目的

采用新的去枕骨取脑技术，提升取脑成功率。

方法

在传统取脑技术的基础上锯开颅骨，以枕外隆凸为中心向下去除部分枕骨至枕骨大孔，暴露端脑、小脑、延髓后面等结构；然后清理小脑幕，切断延髓，在颅底切断相关脑神经，取出脑组织。

结果

取出的脑组织端脑、小脑及脑干结构完整，脑沟内血管清晰，视交叉、嗅束、椎-基底动脉等较完整。

结论

经枕外隆凸开窗取脑技术可有效保护脑标本的完整，提高取脑成功率，对于中枢神经系统实验教学及完善人脑组织资源库具有重要意义。

Abstract

Objective

A new occipital bone removal technology was applied to improve the success rate of brain removal.

Methods

The skull was sawed based on the traditional brain removal technology，and part of the occipital bone was removed downward centered in external occipital protuberance to the foramen magnum，then exposed the telencephalon，cerebellum and posterior medulla oblongata. After that，removed the tentorium cerebelli and cut down the medulla oblongata and the related cranial nerves at the skull base，then removed the brain tissues.

Results

The removed brain tissues had structurally intact telencephalon，cerebellum and brain stem，clear vessels in the cerebral sulci，and relatively intact optic chiasm，olfactory tracts and vertebro-basilar arteries.

Conclusion

Brain removal through a fenestration on the external occipital protuberance can effectively preserve the integrity of brain specimens，and improve the success rate of brain removal，which is of great significance for central nervous system teaching and improvement of human brain tissue repositories.
