 Hi, I'm Dr. Praveen Ghanagi, working as a consultant neurosurgeon and head of the department in Department of Neurosurgery, Manipal Hospital, Bangalore. There are various conditions that can be treated with endoscopic neurosurgery. The most common is being the pituitary adenomas, which are done through the nose. And the next is C.S. of rhinorrhea, that is fluid leakage through the skull base in the nose. And other tumors such as craniopharyngeomas and also clivalric caudomas, which are done through the nose to treat these conditions. And the cranial conditions which can be treated through the endoscope are the hydrocephalus, acrodactyl stenosis hydrocephalus, where small cranial incision is done. And through a small burhole or opening in the skull, the hydrocephalus can be treated. And other commonest procedures is hypertensive hematoma evacation. People with high blood pressure have a basic angle like hematoma where using the endoscope, the hematoma can be evacated in no time.
