Neuroendoscopy. This minimally invasive technique involves threading a thin tube called an endoscope through the mouth, nose, or small incisions in the skull to access or remove brain tissue. The endoscope has a light and camera on the end, and the surgery is performed with tools placed through the endoscope.
Craniotomy: A craniotomy is open brain surgery. A surgeon removes a piece of your skull to access your brain, then replaces the piece after surgery. You may need a craniotomy to remove a tumor, blood clot, arteriovenous malformation, epileptic tissue or to relieve pressure in your brain.
People who have had brain surgery who do experience long-term impairments usually have anomic aphasia. This means their only significant impairment is in word-finding and naming objects. Long-term impairments after brain surgery are typically mild. Most people are able to communicate without a significant difficulty.
Awake brain surgery, also called awake craniotomy, is a type of procedure performed on the brain while you are awake and alert. Awake brain surgery is used to treat some brain (neurological) conditions, including some brain tumors or epileptic seizures.
Pain is usually minimal since there are only a small number of pain nerve endings in the head. Nevertheless, you may experience headaches and other tenderness in the area that was affected.
You won't need to have your head shaved if you are going to have an operation to remove a pituitary tumour through the nose. For tumours in the brainstem or back part of the brain (cerebellum), your surgeon might only need to shave a small area at the back of your head.
The most protracted operation reported lasted for 96 hours and was performed on 4-8 February 1951 in Chicago, Illinois, USA on Mrs Gertrude Levandowski (USA) for the removal of an ovarian cyst. During the operation her weight fell 280 kg (616 lb / 44 st) to 140 kg (308 lb / 22 st).
The condition, called anesthesia awareness (waking up) during surgery, means the patient can recall their surroundings, or an event related to the surgery, while under general anesthesia. Although it can be upsetting, patients usually do not feel pain when experiencing anesthesia awareness.
Brain tissue doesn't have any pain fibers, so while you may feel pressure or vibrations from the surgery, you shouldn't feel pain. We use a local anesthetic (similar to those used at a dentist's office) to numb the muscles, skin and bone that the surgeon has to cut through to get to the brain.
Awake brain surgery is possible because there are no pain receptors in the brain itself. Your scalp will be anesthetized, so you will not feel the operation or any pain.
Some people recover well after brain surgery, but this can take some time. Other people have some problems, or long term difficulties. The problems you may have depends on the area of the brain where the tumour was (or still is if you only had part of the tumour removed).

Traditionally, patients stay one night in intensive care and, if doing well, will be transferred out to a regular hospital room the next day. A majority of the IVs and monitors, such as the bladder catheter, are usually removed on the morning following surgery. You will be allowed to eat a regular breakfast.
Also, keeping the skull nestled within the body is a good way of keeping the bone sterile; the second you start toting vital body parts around, there's always the danger they might pick up airborne germs or, worse, be misplaced.
A neurosurgeon performs the craniotomy by first cutting through the scalp over the area where the brain injury is thought to lie. A hole is then cut into the skull in order to access the brain. This is needed to repair any ruptured blood vessels and to remove the blood clot or growth.
The challenge of brain tumor surgery is removing as much of the tumor as possible without severely damaging normal brain tissue, which demands skill and experience, as well as advanced technology and a well-orchestrated team.
The median survival for patients with low-grade tumors may be more than 10 years, and for patients with high-grade tumors, it ranges from 1 to 3 years.
The 30- and 180-day survival rates for infratentorial craniotomy were 100% for 2021.
Most people wake up a few hours after their brain surgery. But sometimes, your surgeon might decide to keep you asleep for a few days after surgery, to help you recover. They use sedatives to keep you asleep. While you are asleep, you might be breathing through a machine called ventilator.
Patients frequently report having dreams during general anesthesia. The incidence of dreams during general anesthesia that have been reported by patients upon awakening has been reported to range from 10 to 36% [1] and to be higher in younger patients, female patients [2], and patients who received ketamine [3].
A medical drill may be used to make burr holes in the skull. A special saw may be used to carefully cut the bone. The bone flap will be removed and saved. The dura mater (the thick outer covering of the brain directly underneath the bone) will be separated from the bone and carefully cut open to expose the brain.
If you're having general anesthesia, an anesthesiologist will give you medications that make you lose consciousness. After the surgery is complete, he or she will reverse the medication so that you regain consciousness — but you won't be wide awake right away.
Amputated the leg in under 2 1⁄2 minutes (the patient died afterwards in the ward from hospital gangrene; they usually did in those pre-Listerian days). He amputated in addition the fingers of his young assistant (who died afterwards in the ward from hospital gangrene).

Keeping the patient warm turns out to be very important. Operating Rooms are cold. They're cold because the surgeons wear a lot of clothes, and they need to be comfortable to operate. Under anesthesia patients don't manage their temperature very well.
Anesthesiologists regularly take breaks during operations, whereas surgeons do so more rarely.
