Image-guided Endoscopic Expanded Endonasal Approach for Skull Based Tumors

Conditions Related to Image-guided Endoscopic Expanded Endonasal Approach for Skull Base Tumors

Base skull surgery is primarily used to remove various tumors that can compress and injure the delicate and critical structures at the base of the brain. These tumors can affect the anterior cranial fossa under the frontal lobes; the middle cranial fossa, including the cavernous sinus, sella/pituitary region, petrosal region and petrous apex and the infratemporal fossa; and the posterior cranial fossa, including the clivus, foramen magnum, cerebellopontine angle, brain stem, jugular foramen and internal auditory canal. 

There are a number of these tumors: pituitary tumors, meningiomas, craniopharyngiomas, chordomas, schwannomas, neuromas, brain stem astrocytomas and ependymomas, to name just a few.
