A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury, and can also allow doctors to surgically implant devices, such as deep brain ...
In March 2011, investigators from Australia and several other countries published the results of the DECRA [5] trial in The New England Journal of Medicine.This was a randomized trial comparing decompressive craniectomy to best medical therapy run between 2002 and 2010 to assess the optimal management of patients with medically refractory ICP following diffuse non-penetrating head injury.
Awake craniotomy is a neurosurgical technique and type of craniotomy that allows a surgeon to remove a brain tumor while the patient is awake to avoid brain damage. During the surgery, the neurosurgeon performs cortical mapping to identify vital areas, called the " eloquent brain ", that should not be disturbed while removing the tumor.

Hypophysectomy is the surgical removal of the hypophysis (pituitary gland). It is most commonly performed to treat tumors, especially craniopharyngioma tumors. [1] Sometimes it is used to treat Cushing's syndrome due to pituitary adenoma [2] or Simmond's disease [3] It is also applied in neurosciences (in experiments with lab animals) to understand the functioning of hypophysis.
The exact boundaries for removal can vary slightly in practice and between neurosurgeons. [1] It is a treatment option for temporal lobe epilepsy for those in whom anticonvulsant medications do not control epileptic seizures , and who have frequent seizures, and who additionally qualify based on a WADA test to localize the dominant hemisphere ...
