Neuroendoscopy
A neuroendoscopy is a minimally invasive procedure. It involves a neurosurgeon using a small fibre optic camera (typically through the nose or through a small incision in the skull) to help them remove brain tumours or perform other procedures such as a ventriculostomy.
A ventriculostomy involves creating a hole in a cerebral ventricle to help cerebral fluid drain. A neurosurgeon often uses a ventriculostomy to treat hydrocephalus.
