Neurosurgical procedures

Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin from Greek , literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull. The intentional perforation of the cranium exposes the dura mater to treat health problems related to intracranial diseases or release pressured blood buildup from an injury. It may also refer to any "burr" hole created through other body surfaces, including nail beds. A trephine is an instrument used for cutting out a round

Craniotomy is a neurosurgical operation in which a bone flap is temporarily removed from the skull to access the intracranial space. Craniotomies are often critical operations performed for a range of conditions, including tumors, hemorrhages, and removal of foreign bodies such as bullets.

Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain. The surgical operation to produce this condition (corpus callosotomy) involves transection of the corpus callosum, and is usually a last resort to treat refractory epilepsy. Initially, partial callosotomies are performed; if this operation does not succeed, a complete callosotomy is performed to mit

Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types: Functional hemispherectomy refers to a simple surgical disconnection of the diseased hemisphere so that it can no longer send signals to the rest of the brain and body. Anatomical hemispherectomy refers to actual physical removal of the diseased hemisphere from the skull. This surgery is mostly used as a treatment for medically intractable epilepsy, which is the term used when anti-seizure medications are unable to control seizures.

A sympathectomy is an irreversible procedure during which at least one sympathetic ganglion is removed. One example is the lumbar sympathectomy, which is advised for occlusive arterial disease in which L2 and L3 ganglia along with intervening sympathetic trunk are removed leaving behind the L1 ganglion which is responsible for ejaculation. Another example is endoscopic thoracic sympathectomy.

Thalamotomy (; ) is a surgical procedure in which a functional lesion is made into the thalamus to improve the overall brain function in patients. First introduced in the 1950s, it is primarily effective for tremors such as those associated with Parkinson's disease, where a selected portion of the thalamus is surgically destroyed (ablated). Neurosurgeons use specialized equipment to precisely locate an area of the thalamus, usually choosing to work on only one side (the side opposite that of the worst tremors). Bilateral procedures are poorly tolerated because of increased complications and ri

Pallidotomy is a neurosurgical procedure. It is used to treat Parkinson's disease and some other conditions, often as an alternative to deep brain stimulation. It involves placing a tiny electrical probe in the globus pallidus, one of the basal ganglia of the brain, to damage it. Unilateral pallidotomy can cause side effects including problems with language learning, visuospatial constructional ability, and executive functions. Bilateral pallidotomy is not effective, with many severe side effects.

Neurosurgery performed while the patient is awake

Cranioplasty is a surgical operation on the repairing of cranial defects caused by previous injuries or operations, such as decompressive craniectomy. It is performed by filling the defective area with a range of materials, usually a bone piece from the patient or a synthetic material. Cranioplasty is carried out by incision and reflection of the scalp after applying anaesthetics and antibiotics to the patient. The temporalis muscle is reflected, and all surrounding soft tissues are removed, thus completely exposing the cranial defect. The cranioplasty flap is placed and secured on the cranial
