awake craniotomy
A surgical technique where patients remain conscious during tumor resection to preserve neurological function.
Full Definition
Awake craniotomy is a neurosurgical technique in which patients remain awake and responsive during portions of brain tumor surgery, allowing real-time assessment of neurological function. This approach is particularly valuable when tumors are located in or near eloquent brain regions, as it enables surgeons to maximize tumor resection while preserving critical functions such as speech, motor control, and cognition. Editors must understand the specific phases of awake surgery, patient selection criteria, and the unique considerations for reporting outcomes and complications.
Usage
Usage note: Distinguish from 'conscious sedation' which doesn't allow active patient participation; specify mapping techniques used.
