Extended frontotemporal epidural approach to cavernous sinus: surgical anatomy and technique
1Department of Neurosurgery, Huashan Hospital, Shanghai Medical University, Shanghai 200040, China.
Objective:
To investigate the surgical technique of trans-frontotemporal extended epidural approach to the cavernous sinus.
Methods:
A microsurgical study on the exposure and dissection of the cavernous sinus and its surrounding structures on cadavers was performed via an extended epidural approach with frontotemporal skull-base craniectomy.
Results:
The extended epidural approach offered an appropriate exposure of the cavernous sinus with minimal brain retraction and nerve damage.
Conclusions:
The extended frontotemporal epidural surgical approach is superior to the routine intradural or combined epi- and intradural approaches. It is suitable for most of the cavernous sinus surgeries.
