Minimally Invasive Neurosurgery describes any procedure that is less invasive than an open surgery used for the same purpose, and is redefining the field of neurosurgery. Minimally invasive surgery (MIS) procedures usually involve laparoscopic devices and remote-controlled manipulation of surgical instruments with observation of the surgical field through a scope, either micro or endo.

The advantage of this being shorter hospital stays, quicker recovery time and better cosmesis. Your surgeon uses an array of latest equipment like fiber optic cables, miniature video cameras, special surgical instruments and external video monitors.

However, MIS may not be suitable for all patients, especially if the tumour is too large and the approach is carefully tailored to your specific needs by your doctor, given the goal is maximum safe resection of tumour with minimal collateral damage.
