Bifrontal craniotomy: a bifrontal craniotomy is a surgical process which is used to target different tumors or malfunctioning areas of the brain.http://www.Pneumatocele: A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation.Penetrating head injuryNeurooncology: Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these). Among the malignant brain cancers, gliomas of the brainstem and pons, glioblastoma multiforme, and high-grade (highly anaplastic) astrocytoma are among the worst.Cranio-corpography: Cranio-Corpo-Graphy (CCG) is a medical investigation and measurement procedure developed in 1968 by German neurootologist Claus-Frenz Claussen. It documents and evaluates disorders of the equilibrium function measured by investigation procedures such as the Unterberger test, the LOLAVHESLIT test, the NEFERT test, the Romberg's test and the WOFEC test.Subdural hematomaInfectious intracranial aneurysm: An infectious intracranial aneurysm (IIA, also called mycotic aneurysm) is a cerebral aneurysm that is caused by infection of the cerebral arterial wall.Falx cerebri: The falx cerebri is also known as the cerebral falx, named from its sickle-like form. It is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.MeningiomaSubdural space: The subdural space (or subdural cavity) is a potential space that can be opened by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver. In the cadaver, due to the absence of cerebrospinal fluid in the subarachnoid space, the arachnoid mater falls away from the dura mater.Chen Zhongwei: Chen Zhongwei (Chinese:陈中伟, 1929–2004) was an expert of orthopedic surgery and microsurgery, one of the pioneers of the process of reattaching severed limbs.Altered level of consciousnessEpidural hematomaDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.XYZ file format: The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.RhinorrheaEagle syndrome: Eagle syndrome (also termed stylohyoid syndrome styloid syndrome, styloid-stylohyoid syndrome, or styloid–carotid artery syndrome) is a rare condition caused by an elongated or deviated styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures giving rise to pain.Stereotactic surgeryAmoebic brain abscessNeurosurgery: Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.AANS – Patient InformationHematoceleHyperintensitySurgical scissors: Surgical scissors are surgical instruments usually used for cutting. They include bandage scissors, dissecting scissors, iris scissors, operating scissors, stitch scissors, tenotomy scissors, Metzenbaum scissors, plastic surgery scissors, and Mayo scissors.Cerebellar stroke syndromeVentriculostomyRotation flap: A rotation flap is a semicircular skin flap that is rotated into the defect on a fulcrum point. Rotation flaps provide the ability to mobilize large areas of tissue with a wide vascular base for reconstruction.Brain injury: A brain injury is any injury occurring in the brain of a living organism. Brain injuries can be classified along several dimensions.Elias Rudolph Camerarius, Sr.: Elias Rudolph Camerarius, Sr. (1641–1695) was a professor of medicine who notably wrote books on the palpitations of the heart, pleurisy, skull fractures, and the use of medicinal plants.Subarachnoid hemorrhageUniversity of Miami Division of Surgical Neurooncology: The Division of Surgical Neurooncology in the Department of Neurological Surgery and Sylvester Comprehensive Cancer Center at the University of Miami is one of the largest and most complete programs for brain tumor treatment in the United States. As the only academic medical center in the region, the University of Miami offers a unique and comprehensive approach to these conditions, with interdisciplinary discussion between neurosurgery, neurology, radiation oncology, and medical oncology.Procedural sedation and analgesia: Procedural sedation and analgesia, previously referred to as conscious sedation, is defined as "a technique of administering sedatives or dissociative agents with or without analgesics to induce a state that allows the patient to tolerate unpleasant procedures while maintaining cardiorespiratory function."Great cerebral vein: The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum (brain). It is also known as the "vein of Galen" (VG), named for its discoverer, the Greek physician Galen.Intracranial hemorrhageSpinal decompression: Spinal decompression is the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.Recurrent artery of Heubner: Heubner's artery (also known as the recurrent artery of Heubner or Medial Striate A.), named after the German paediatrician Otto Heubner is a branch from the anterior cerebral artery, typically from the proximal A2 segment or distal A1 segment, or at the level of the optic chiasm.Superior orbital fissure: The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.Cranial vault: The cranial vault is the space in the skull within the neurocranium, occupied by the brain. In humans, the size and shape of the brain, may be affected by the size of the vault as shown in craniometry, but studies relating it to intelligence have found no conclusive evidence.
