Craniotomy for Skull Base Tumors

Cranial base surgery involves treatment of the congenital, vascular, neoplastic, endocrine and traumatic lesions involving the base of cranium.
This surgery is the brainchild of three specialties: craniofacial surgery, neurosurgery and neuro-otology. Anatomically the skull base is divided into three subdivisions. The anterior skull base, the lateral skull base and the posterior or extreme lateral skull base.Anterior Skull Base

The anterior skull base is further subdivided into midline and paramedian regions. Midline lesions include congenital encephaloceles, craniofacial clefts, or tumors (such as pituitary lesions or craniopharyngiomas). Paramedian lesions include orbital tumors and locoregional extensions of paranasal sinus and head and neck tumors.

Lateral Skull Base

The lateral skull base involves lesions in the infratemporal fossa as described. These consist of glomus jugulare tumors, clival tumors and petrous apex lesions such as cholesterol cysts. Other lesions are further anterior extensions including juvenile angiofibromas and nasopharyngeal carcinomas. Lateral skull base surgery also includes transtemporal lesions (middle cranial fossa) including sphenoid wing meningiomas, neuromas of the trigeminal nerve and vascular lesions such as internal carotid artery aneurysms. We have engaged in more than 500 of thes type of operations.

Posterior or Extreme Lateral Skull Base

Surgery of the extreme lateral skull base involves the cerebellopontine (CP) angle including acoustic neuromas, microvascular decompression of cranial nerves, meningiomas of the posterior fossa, and surgery of the craniocervical junction.

The Minimally Invasive Skull Base Center incorporates an innovative microneurosurgery program offering minimally invasive craniotomy procedures when appropriate. This allows a non-biased approach whereby the appropriate surgical approach is selected based on patient, tumor and anatomical factors rather than surgeon preference or training.

Our multispecialty team allows a multimodality approach incorporating endonasal and craniotomy surgical procedures along with endovascular interventional approaches and Novalis radiosurgery, all with the ultimate goal of patient’s safety and best treatment.

Barcelona Neuroinstitute has extensive experience treating such conditions as: acoustic schwannoma (neuroma), meningiomas, chordomas, chondromas, craniopharyngiomas, epidermoid cysts, and many others.
