A brain surgery is done to treat the brain and its parts. There can be various types of brain surgeries:
Craniotomy - This involves creating an incision for a bone flap for removing tumours, aneurysm, or abnormal brain tissues.
Biopsy - This involves removing a small part of brain tissue to examine under a microscope
Minimally invasive endonasal endoscopic surgery - In this case, surgeons remove tumours or lesions through nose and sinus with the help of an endoscope.
Minimally invasive neuroendoscopy - In this case, endoscopes are used to remove brain tumours
Deep brain stimulation - This involves inserting a small electrode in your brain to send electrical signals
