What is Skull Base?
‘Skull base’ is a term used to describe the gap between the lower part of the brain and the skull directly below it. The skull consists of blood vessels that supply the brain with nutrients and oxygen, as well as nerves that are critical to functions such as vision, smell, hearing, facial movement and breathing. The term ‘Lateral skull base’ therefore refers to the portion of the skull base located at the side of the skull that includes the temporal bone, infratemporal fossa, clivus, and middle and posterior fossae.
How dangerous are tumors on the lateral skull base?
Any tumors present on the lateral skull base can prove to be extremely risky to the brain stem. This is the portion that connects the brain to the spinal cord and is one of the most delicate and important parts of the body’s neurological system.
How is lateral skull base surgery performed?
To operate on the lateral skull base region without disrupting the brain function, advanced surgical techniques such as the lateral skull base surgery can be performed either endoscopically or by using a microsurgical or microscopic keyhole approach. A wide range of tumors such as meningiomas, acoustic neuromas, glioma tumors, encephaloceles, cholesteatomas, schwannomas, and glomus tumors can be treated using this procedure. The surgery involves re-sectioning the tumor completely by removing the small pieces of the abnormal tissue. This is done using a neurophysiological monitoring system that tracks electrical activity within the brain to ensure that brain functioning remains healthy throughout the operation.
