What is minimally invasive neurosurgery?

Smaller incisions, less muscle damage, faster recovery — where it applies. But smaller is not automatically better; the operation still has to fit the problem.

Minimally invasive neurosurgery covers techniques that achieve the same surgical goal through a smaller opening, with less disruption to healthy tissue.

On the spine, this includes tubular microdiscectomy, minimally invasive lumbar decompression, and percutaneous pedicle screw fixation. Recovery is usually faster, blood loss is lower, and post-operative pain is less.

On the cranial side, endoscopic transnasal surgery for pituitary tumours goes through the nose without any external incision. Endoscopic third ventriculostomy treats hydrocephalus without inserting a shunt. Keyhole craniotomies use small openings for selected tumours.

The important honest caveat: minimally invasive is a tool, not a virtue. If a problem is best solved with a traditional open approach, doing it through a smaller hole for the sake of it makes surgery harder and outcomes worse. I will always recommend the approach that gives the best result for your specific case.
