Brain Tumor Surgery

"Patients with complete removals have fewer complications in radiotherapy and get more benefit from chemotherapy, so they gain in survival and quality of life".


The surgical treatment of brain tumors requires expert and dedicated human teams and also advanced technological means.

The Clinica Universidad de Navarra has a multidisciplinary Area of Brain Tumors dedicated exclusively to the treatment of this type of tumor.

  • To achieve an exact and precise diagnosis of the tumor.
  • This implies having a specialized neuropathology laboratory capable of advanced molecular determinations.
  • Decrease the pressure on the healthy brain to improve symptoms.
  • The total removal of the tumor can cure the tumor or facilitate the effect of other treatments.
  • Modern neurosurgery achieves, in most cases, the removal of tumors without adding neurological lesions to the patient, even with improvement of existing lesions.

When is surgery for a brain tumor indicated?

Brain injuries that may require surgery as part of the comprehensive treatment of the disease include brain metastases from other tumors.

Primary cranial tumors (neuronal or glioneuronal tumors, gliomas, neurinomas, meningiomas, pituitary adenomas, craniopharyngiomas, central nervous system lymphoma) also require surgery.

Most frequent indications:

  • Brain Tumors
  • Brain Metastases

Do you have any of these diseases?

Surgical treatment may be indicated

How is brain tumor surgery performed?

The Clinic has a fluorescent surgical microscope that achieves the total removal of brain tumors in up to 83% of cases, when with conventional techniques it is only achieved in 30% of the interventions.

With this system, the surgeon can perfectly distinguish between tumor mass and brain tissue to completely remove the tumor, regardless of its size and the region of the head where it is located.

  • Neurophysiological monitoring in the operating room: it is possible to monitor the patient, sometimes even doing the operation with the patient awake. This helps to determine whether or not the surgery can continue in a certain area without producing sequelae. It increases removal and decreases complications.
  • Intraoperative image-guided surgery: In all tumors, the image from the previous magnetic resonance is used as a map for a browser that helps the surgeon. In some special cases, due to the complexity of the tumor, it may be necessary to perform a new MRI during the operation to update that map.

Where do we do it?


The Department of Neurosurgery
at the Clínica Universidad de Navarra

The Neurosurgery Department has specialists with a great deal of experience in care and research and the most advanced technology.

We are the only Spanish center that incorporates high field intraoperative magnetic resonance (3T). This allows the maximum precision and control in cranial surgery.

We are the Spanish medical center with the most experience in Parkinson's surgery by means of deep brain stimulation. We have the latest technology with localized ultrasound (HIFU) and extensive experience in treating essential tremor and Parkinson's disease without an incision.

Treatments we perform

Why in Navarre?

  • The only Spanish center with a high field intraoperative magnetic resonance (3T).
  • Precision and minimally invasive surgery.
  • Experts in the use of HIFU for the treatment of tremor.
