awake craniotomy
A neurosurgical procedure performed while the patient is conscious to allow real-time testing of brain function during tumor removal.
Full Definition
Awake craniotomy is a specialized neurosurgical technique in which the patient remains conscious during critical portions of brain tumor surgery. This approach allows for real-time neurological testing and cortical stimulation mapping to identify and preserve eloquent brain functions such as speech, language, and motor control. The procedure typically involves initial sedation for the craniotomy, awakening for tumor resection near functional areas, and possible re-sedation for closure. This technique is particularly valuable for tumors in or near eloquent cortex.
Usage
Usage note: Always specify the functional testing performed during the awake portion.
