Our Skull Base Laboratory is intended to advance surgical techniques in Neurosurgery and to study and test new surgical strategies.

The anatomy of the brain and the base of the skull is the most complex of the body. A thorough knowledge in 3 dimensions of this extremely complex environment is a prerequisite for the practice of this surgery.

This knowledge allows the Neurosurgeon to predict the position of critical structures, anticipate and improve the execution of his actions.
The environment of our laboratory allows to recreate the conditions of a surgical intervention and thus to simulate, develop and test new surgical techniques.
It also allows repetition of complex and meticulous steps for the practice of neurosurgery in these complex regions.


The laboratory has 4 work stations allowing the organization, several times a year, of practical training courses, intended for neurosurgeons wishing to discover and improve their skills in these advanced techniques.
