How would a doctor operate on a brain?

If the brain is covered by bones, do they have to brake them to get to the brain, or is there another way to get there?



I'm only 15, so please don't use crazy medical terms that I won't understand lol :)How would a doctor operate on a brain?
I had to have brain surgery to remove a brain tumor. While I was not awake through the process, I know how it was done. First they cut my scalp and laid it back. They did not shave the scalp like you see in movies. they then drilled small holes in the skull (three or four, I believe four) over the area where the tumor was. They connected the holes with a saw and removed the cut out plate. The surgeon then cut out the tumor using a pre-surgical GPS map as a guide being careful to not hit major blood vessels, but going deep enough to "get it all".

Then they put the skull plate back on and used titanium "buttons" to keep the plate in place. They then covered the plate with my scalp and used surgical staples to hold the scalp together. Unlike other bones in your body that tend to knit after being cracked or broken, your skull is less likely to knit itself together. The titanium buttons do not set off the alarms at airport security scanners. God I hope I never have to go through that again. It took about 5 hours. I had a great surgeon and am thankful that this all took place before Obamacare.
With a hand drill three holes are drilled in the scull bone, forming the corners of a triangle. A strip of aluminium is slid in one hole and out another to protect the covering of the brain. An electric device is used to cut the bone from one hole to another. After all three cuts are made the patient is put to sleep temporarily because the removal of the bone is painful.How would a doctor operate on a brain?
That would depend upon which part of the brain is to be operated on. A lobotomy is done through the eye socket behind the eye. The bone is broken.



Usually for a small hole, a drill is used. For larger holes, a saw is used. Yes, the bone is sawed and removed for the operation. It depends upon what must be done.



Most surgeries are done with the patient awake and answering questions. That way the doctor can better tell what areas are being affected. Patients are asked to count or remember things. They have even reported smelling things just with a touch in the right spot.
In most cases, the skull must be cut through to access the brain.



New techniques, such as an endoscope through the nose can allow the surgeon to perform a much less invasive surgery. http://www.sciencedaily.com/videos/2005/鈥?/a>
Have you ever seen the bits carpenters use to drill a hole in a door for a doorknob? It's very similar. The neurosurgeon whips out the ol' Black and Decker, and off they go.
I believe they drill a hole in the skull somehow to get to the brain. I'm not an expert though lol.
