Neurosurgery
In different countries, there are different requirements for an individual to legally practice neurosurgery, and there are varying methods through which they must be educated. In most countries, neurosurgeon training requires a minimum period of seven years after graduating from medical school.[2]
Neurosurgery
In the United States, a neurosurgeon must generally complete four years of undergraduate education, four years of medical school, and seven years of residency (PGY-1-7).[3] Most, but not all, residency programs have some component of basic science or clinical research. Neurosurgeons may pursue additional training in the form of a fellowship after residency, or, in some cases, as a senior resident in the form of an enfolded fellowship. These fellowships include pediatric neurosurgery, trauma/neurocritical care, functional and stereotactic surgery, surgical neuro-oncology, radiosurgery, neurovascular surgery, skull-base surgery, peripheral nerve and complex spinal surgery.[4] Fellowships typically span one to two years. In the U.S., neurosurgery is a very small, highly competitive specialty, constituting only 0.5 percent of all physicians.[5]
Neurosurgery, or the premeditated incision into the head for pain relief, has been around for thousands of years, but notable advancements in neurosurgery have only come within the last hundred years.[6]
The Incas appear to have practiced a procedure known as trepanation since before European colonization.[7] During the Middle Ages in Al-Andalus from 936 to 1013 AD, Al-Zahrawi performed surgical treatments of head injuries, skull fractures, spinal injuries, hydrocephalus, subdural effusions and headache.[8] During the Roman Empire, doctors and surgeons performed neurosurgery on depressed skull fractures.[9][10] Simple forms of neurosurgery were performed on King Henri II in 1559, after a jousting accident with Gabriel Montgomery fatally wounded him. Ambroise Paré and Andreas Vesalius, both experts in their field at the time, attempted their own methods, to no avail, in curing Henri.[11] In China, Hua Tuo created the first general anaesthesia called mafeisan, which he used on surgical procedures on the brain.[12]
A survey done in 2010 on 100 most cited works in neurosurgery shows that the works mainly cover clinical trials evaluating surgical and medical therapies, descriptions of novel techniques in neurosurgery, and descriptions of systems classifying and grading diseases.[21]
The main advancements in neurosurgery came about as a result of highly crafted tools. Modern neurosurgical tools, or instruments, include chisels, curettes, dissectors, distractors, elevators, forceps, hooks, impactors, probes, suction tubes, power tools, and robots.[22][23] Most of these modern tools have been in medical practice for a relatively long time. The main difference of these tools in neurosurgery, were the precision in which they were crafted. These tools are crafted with edges that are within a millimeter of desired accuracy.[24] Other tools, such as hand held power saws and robots have only recently been commonly used inside of a neurological operating room. As an example, the University of Utah developed a device for computer-aided design / computer-aided manufacturing (CAD-CAM) which uses an image-guided system to define a cutting tool path for a robotic cranial drill.[25]
Specialized branches have developed to cater to special and difficult conditions. These specialized branches co-exist with general neurosurgery in more sophisticated hospitals. To practice advanced specialization within neurosurgery, additional higher fellowship training of one to two years is expected from the neurosurgeon.Some of these divisions of neurosurgery are:
Neuroanesthesia is a field of anesthesiology which focuses on neurosurgery. Anesthesia is not used during the middle of an "awake" brain surgery. Awake brain surgery is where the patient is conscious for the middle of the procedure and sedated for the beginning and end. This procedure is used when the tumor does not have clear boundaries and the surgeon wants to know if they are invading on critical regions of the brain which involve functions like talking, cognition, vision, and hearing. It will also be conducted for procedures which the surgeon is trying to combat epileptic seizures.[36]
Neuroradiology methods are used in modern neurosurgery diagnosis and treatment. They include computer assisted imaging computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), magnetoencephalography (MEG), and stereotactic radiosurgery. Some neurosurgery procedures involve the use of intra-operative MRI and functional MRI.[38]
Using stereotaxy neurosurgeons can approach a minute target in the brain through a minimal opening. This is used in functional neurosurgery where electrodes are implanted or gene therapy is instituted with high level of accuracy as in the case of Parkinson's disease or Alzheimer's disease. Using the combination method of open and stereotactic surgery, intraventricular hemorrhages can potentially be evacuated successfully.[24] Conventional surgery using image guidance technologies is also becoming common and is referred to as surgical navigation, computer-assisted surgery, navigated surgery, stereotactic navigation. Similar to a car or mobile Global Positioning System (GPS), image-guided surgery systems, like Curve Image Guided Surgery and StealthStation, use cameras or electromagnetic fields to capture and relay the patient's anatomy and the surgeon's precise movements in relation to the patient, to computer monitors in the operating room. These sophisticated computerized systems are used before and during surgery to help orient the surgeon with three-dimensional images of the patient's anatomy including the tumor.[39] Real-time functional brain mapping has been employed to identify specific functional regions using electrocorticography (ECoG)[40]
A common procedure performed in neurosurgery is the placement of ventriculo-peritoneal shunt (VP shunt). In pediatric practice this is often implemented in cases of congenital hydrocephalus. The most common indication for this procedure in adults is normal pressure hydrocephalus (NPH).[45]
Surgery for chronic pain is a sub-branch of functional neurosurgery. Some of the techniques include implantation of deep brain stimulators, spinal cord stimulators, peripheral stimulators and pain pumps.[47]
Neurosurgery, the official journal of the CNS, publishes top research on clinical and experimental neurosurgery covering the latest developments in science, technology, and medicine. The journal attracts contributions from the most respected authorities in the field. It includes a wealth of information applicable to researchers and practicing neurosurgeons.
A physician who specializes in neurosurgery. Neurosurgeons are not just brain surgeons, they are medically trained neurosurgical specialists who can also help patients suffering from back and neck pain as well as a host of other illnesses ranging from trigeminal neuralgia to head injury and Parkinson's disease.
During this residency training, neurosurgeons are trained in all aspects of neurosurgery, including the cerebrovascular system, the spine and spinal cord, trauma, tumors, pain management and pediatric surgery. Residents complete a minimum of 60 months of training in the neurological sciences, with at least 36 of those months are devoted to clinical neurosurgery and a minimum of 3 months devoted to clinical neurology.
