Skull Base Tumors

Skull base tumors are a group of tumors that grow along different areas under the brain or within the bottom part of the skull.

While most of the tumors are benign, due to their location, which is close to the brain and various nerves, their growth can cause significant problems.

If you are having symptoms such as hearing changes or cognitive changes, call 714-456-7017 or request an appointment online ›.

When it comes to tumors of the skull base, there are many types. We treat all of them, including:

The symptoms are completely dependent on the size and location of the tumor.

They range greatly from small periodic changes, such as headaches, dizziness or hearing changes.

Symptoms can also be more severe, including:

  • Complete loss of vision and/or hearing
  • Facial paralysis
  • Diminished cognitive function

If your symptoms are staying the same or worsening, consult our physicians for an evaluation.

Only a thorough exam and diagnostic tests performed by a physician can determine whether the cause of the symptoms is a tumor.

Diagnosis of skull base tumors requires a careful history along with a physical examination and diagnostic tests.

Diagnostic tests may include a CT and/or MRI, which can help determine the extent of the tumor.

Tests of your hearing and balance may also be conducted.

The skull base surgery team at UC Irvine Health uses minimally invasive approaches for certain skull base tumors including:

  • Endoscopic approaches
  • Computer-based image guidance
  • Lasers for tumor removal
  • Ultrasound removal of bone and tumors
  • Intra-operative MRI when indicated

Other types of tumors, sizes of tumors, or their location dictates a more invasive surgery.

Further treatment can include radiation therapy and or stereotactic radiosurgery.
