In the brain ("brain surgery") some of the conditions commonly seen include:
- Brain aneurysms - weaknesses on blood vessels that can burst, leading to death or stroke
- Carotid stenosis - narrowing of the arteries supplying the brain, possible leading to stroke or a warning 'TIA'
- Vascular malformations - which can bleed - some are congenital (meaning we are born with them), and some develop later in life
- Brain tumours- both benign (often curable with surgery) and malignant ( often incurable, but sometimes controllable with surgery)
- Acoustic neuromas- a kind of tumour at the base of the brain, related to the hearing nerves
- Trigeminal neuralgia- terrible 'spasms' of facial pain that are curable with surgery
- Hemifacial spasm - involuntary twitching on one side of the face - often curable with surgery
- Hydrocephalus- a build up of fluid in the brain - treatable with an endoscope (a surgical camera) or with a shunt (to divert the fluid)
- Head injury - blood clots ('haematomas') can develop after a head injury and some need to be removed with surgery
