What is the skull base?
The skull base is the complex lower part of the skull surrounding structures at the junction of the brain, cranial nerves, blood vessels and the upper airway. Conditions in this region can be difficult to evaluate and may need specialist multidisciplinary assessment.
Common skull base conditions
- Pituitary and nearby sellar lesions
- Meningiomas involving the skull base
- Selected cranial nerve disorders
- Other lesions affecting the skull base and adjacent structures
Symptoms can vary
Depending on the structure involved, symptoms may include visual changes, headache, hormonal abnormalities, facial sensory symptoms, hearing or balance problems, or other cranial nerve findings. These symptoms have many possible causes and require appropriate evaluation.
Diagnosis and treatment planning
Assessment can include neurological examination and targeted imaging such as MRI or CT. Treatment depends on the lesion and may involve observation, medication, surgery, radiosurgery or a multidisciplinary plan depending on the diagnosis.
Frequently asked questions
What imaging is used for skull base problems?
