Endoscopic minimally invasive brain surgery is a technique that uses an endoscope, a thin, flexible tube with a camera and light at the end, to perform surgery on the brain through small incisions. This approach is designed to minimize damage to healthy brain tissue and reduce recovery time for the patient. The endoscope provides the surgeon with a magnified, high-definition view of the surgical area, allowing for precise navigation and manipulation of instruments.

Endoscopic brain surgery is used for a variety of conditions, including the removal of brain tumors, treatment of hydrocephalus, and repair of cerebrospinal fluid leaks, among others. The small incisions and minimal disruption to the surrounding brain tissue can lead to less postoperative pain, shorter hospital stays, and quicker recovery times for patients.

During the procedure, the surgeon inserts the endoscope through a small incision in the skull or other entry points such as the nose (in the case of endoscopic endonasal surgery). The endoscope's camera transmits images to a monitor, guiding the surgeon's movements as they operate.

Despite its benefits, endoscopic brain surgery requires specialized training and expertise, as the surgeon must navigate delicate structures within the brain with precision. This technique is a significant advancement in neurosurgery, offering patients a less invasive option with potential for better outcomes and a faster recovery.
