Depending on the requirements of the operation, either rigid or flexible endoscopes are used in intracranial surgery. With endoscopes of differing viewing angles of 0°, 30°, 70° an 120°, the neurosurgeon can see into the brain to an extent that was not previously possible with a microscope and can carry out more extensive surgery.
Indications for the use of the neuroendoscope in neurosurgery are as follows:
- Occlusive hydrocephalus (ventriculostomy)
- Intraventricular processes (e.g. tumors and cysts)
- Arachnoidal cysts and cystic cerebral tumors
- Intraventricular hemorrhages and other intraventricular interventions
- Endoscopically assisted neurosurgery (base of the skull)
- Transnasal transsphenoidal pituitary gland surgery
