'''Neurosurgery''' is the [[surgery|surgical]] discipline focused on treating those [[central nervous system|central]] and [[peripheral nervous system]] diseases amenable to mechanical intervention.

==Definition and scope== 
{{cquote|''Neurological Surgery is a discipline of medicine and that specialty of surgery which provides the operative and nonoperative management (ie, prevention, diagnosis, evaluation, treatment, critical care, and rehabilitation) of disorders of the central, peripheral, and autonomic nervous systems, including their supporting structures and vascular supply; the evaluation and treatment of pathological processes that modify the function or activity of the nervous system, including the hypophysis: and the operative and nonoperative management of pain. As such, neurological surgery encompasses the surgical, nonsurgical and stereotactic radiosurgical treatment of adult and pediatric patients with disorders of the nervous system: disorders of the brain, meninges, skull base, and their blood supply, including the surgical and endovascular treatment of disorders of the intracranial and extracranial vasculature supplying the brain and spinal cord; disorders of the pituitary gland; disorders of the spinal cord, meninges, and vertebral column, including those that may require treatment by fusion, instrumentation,or endovascular techniques; and disorders of the cranial and spinal nerves throughout their distribution''.}}

==Neurosurgical methods==

Neuroradiology methods are used in modern neurosurgical diagnosis and treatment, including [[X-ray computed tomography|computer assisted imaging computed tomography (CT)]], [[mri|magnetic resonance imaging (MRI)]], [[Positron emission tomography|positron emission tomography (PET)]], [[Magnetoencephalography|magnetoencephalography (MEG)]], and the [[stereotactic surgery]]. Some neurosurgical procedures involve the use of MRI and [[functional MRI]] intraoperatively.

Microsurgery is utilized in many aspects of neurological surgery. Microvascular anastomosis are required when EC-IC surgery is performed. The clipping of aneurysms is performed using a microscope. Minimally invasive spine surgery utilizes these techniques. Procedures such as microdiscectomy, laminectomy, and artificial discs rely on microsurgery.<ref>http://www.neurosurgery.org/cybermuseum/microneurohall/arhoton.html</ref>

Minimally invasive endoscopic surgery is utilized by [[neurosurgeons]]. Techniques such as endoscopic endonasal surgery is used for [[pituitary tumors]], craniopharyngiomas, chordomas, and the repair of [[cerebrospinal fluid]] leaks. Ventricular endoscopy is used for [[colloid cyst]]s and neurocysticercosis. Endoscopic techniques can be used to assist in the evaculation of [[hematomas]] and [[trigeminal neuralgia]].
Repair of craniofacial disorders and disturbance of cerebrospinal fluid circulation is done by neurosurgeons, and depending on the situation, plastic surgeons. Conditions such as chiari malformation, craniosynostosis, and syringomyelia are treated. This is called [[cranioplasty]].

Neurosurgeons are involved in Stereotactic Radiosurgery along with Radiation Oncologists for [[tumor]] and [[AVM]] treatment. Radiosurgical methods such as [[Gamma knife]], [[Cyberknife]] and [[Novalis Shaped Beam Surgery]] are used.<ref>http://neurosurgery.ucla.edu/body.cfm?id=952</ref>

Neurosurgeons have begun to utilize endovascular image guided procedures for the treatment of [[aneurysm]]s, AVMs, carotid stenosis, strokes, and spinal malformations, and vasospasms. Also, nonvascular procedures such as Vertoplasty and Kyphoplasty are used by neurosurgeons. Techniques such as angioplasty, stenting, clot retrieval, embolization, and diagnostic angiography are utilized.<ref>http://www.mir.wustl.edu/neurorad/internal.asp?NavID=74</ref>

==Procedures==
These include:
*[[Commissurotomy]]
*[[Decerebration]]
*[[Decortication (brain)]]
*[[Hemispherectomy]]
*[[Pyramidectomy]]
*[[Sympathectomy]]
*[[Tractotomy]]
*[[Vagotomy]]

==Conditions==
Neurosurgical conditions include primarily [[human brain|brain]], [[spinal cord]] and [[peripheral nervous system|peripheral nerve]] disorders.

Conditions treated by neurosurgeons include:

*[[Spinal disc herniation]]
*[[Spinal stenosis]]
*[[Hydrocephalus]]
*[[Head trauma]] (brain hemorrhages, skull fractures, etc.)
*[[Spinal cord]] [[Physical trauma|trauma]]
*[[Physical trauma|Traumatic injuries]] of [[peripheral nervous system|peripheral nerves]]
*[[Brain tumor]]s
*[[Tumor]]s of the [[vertebral column|spine]], [[spinal cord]] and [[peripheral nervous system|peripheral nerves]]
*[[Cerebral aneurysm]]s
*Some forms of [[stroke|hemorrhagic stroke]], such as [[subarachnoid hemorrhage]]s, as well as intraparenchymal and intraventricular [[hemorrhage]]s
*Some forms of pharmacologically resistant [[epilepsy]]
*Some forms of [[movement disorder]]s (advanced [[Parkinson's disease]], [[chorea]], [[hemiballism]]) - this involves the use of specially developed minimally invasive [[stereotaxy|stereotactic]] techniques (functional, stereotactic neurosurgery)
*Intractable pain of cancer or trauma patients and cranial/peripheral nerve pain
*Some forms of intractable [[psychiatric]] disorders
*[[Malformation]]s of the [[nervous system]]
*Carotid artery stenosis
*Arteriovenous malformations of the brain and spinal cord
*Carpal Tunnel Syndrome
*Moyamoya disease
