Traveling to Utah?
Let us help you navigate your visit.
Lateral skull base tumors are at the back of the skull base and are typically benign. Some examples include:
- Acoustic Neuromas鈥擭oncancerous tumors growing on the nerve leading from the inner ear to the brain. Slow growing.
- Meningiomas鈥擜 tumor found on the tissue covering the brain or spinal cord in the skull interior. Typically benign. These can also be anterior tumors.
- Paragangliomas鈥擣ound in the head and neck. Rarely cancerous.
Symptoms of Lateral Skull Base Tumors

- hearing loss,
- headaches,
- balance problems,
- problems swallowing, and
- voice hoarseness.

Lateral Skull Base Surgery
Lateral skull base surgery is primarily for removing meningiomas, acoustic tumors, and paragangliomas. The standard treatment for these tumors is microsurgery. Common microsurgery approaches are:
- translabyrinthine,
- middle fossa, and
- retro sigmoid.
We make these approaches through an incision near the ear. We then drill holes in the bone of the skull base to expose the tumor. Finally, we remove the tumor with the visual aid of an operating microscope and an endoscope, if appropriate.
In order to reconstruct the bone of the skull base, we may need to use an abdominal fat graft. This means we take a strip of fat from your abdomen.
Our team of doctors works together to remove the tumor and achieve the best outcome for you. Members of that team can include:
- a neurosurgeon,
- a neurotologist,
- an anesthesiologist.
Radiation
Stereotactic radiation allows us to sculpt the dose to the size and shape of the tumor without damaging nearby healthy brain tissue and the optic nerve. We may recommend radiation if:
- you aren't a good candidate for surgery because of your age and overall health.
- we need to target remaining cells that could cause the tumor to grow back.
- surgery is too risky.
We use a computer to calculate the appropriate radiation dose for your tumor. Your radiation treatment, which is delivered externally to your body, may require multiple outpatient visits.
- Stereotactic Radiosurgery -- This technique delivers radiation in one to five doses. No actual cutting takes place.
- Radiotherapy -- This technique delivers radiation in a larger number of doses.
Patients do not lose their hair and are often able to return to work the next day.
Chemotherapy
We rarely choose chemotherapy as a treatment for skull base tumors because most are benign (not cancerous). However, for some malignant tumors, chemotherapy is used to destroy cancer cells or prevent more from growing.
For some patients with acoustic tumors in both ears, we may recommend chemotherapy to keep the tumor from growing and keep your hearing intact.
Recovery After Skull Base Surgery
After surgery, patients may need to stay in the hospital for a period of four to seven days.
Medication can help relieve your pain and prevent brain swelling and seizure. Levels of exercise will vary, but many patients are encouraged to walk the day after surgery.
Our skull base surgeons will follow up with you to monitor changes in symptoms. More imaging tests will be needed.
Most patients are able to return to work and normal daily activities after recovery.
