Image-Guided Stereotactic Surgery
What is image-guided stereotactic surgery?
Stereotactic surgery, also called stereotaxy, uses advanced computers to detect a brain tumor and create a three-dimensional image of it.
Stereotactic surgery, also called surgical navigation, is a type of intraoperative monitoring (monitoring of the brain during surgery) that enables the neurosurgeon to precisely map the location of the tumor and determine the most effective way to remove it. It enables the neurosurgeon to see the brain during surgery to remove as much of the tumor as possible without damaging vital areas.
Stereotactic surgery is especially useful for tumors located deep in the brain. The CyberKnife is an example of stereotactic radiosurgery.
Types of brain cancers and tumors treated with image-guided stereotactic surgery:
The Gamma Knife is often used as a treatment method for:
- Craniopharyngiomas (pituitary tumor)
- Metastatic brain tumors
- Pituitary adenomas
