Awake craniotomy - for management of intracranial lesions safely in eloquent areas of brain.

ABSTRACT

The awake craniotomy is a procedure where the craniotomy and excision of the lesion is done in awake patient without general anaesthesia. This surgical technique enable surgeons to avoid damaging normal cerebral regions and allow real-time patient feedback while operating on important functional areas of brain like motor cortex and speech areas (motor, somatosensory, and language areas). Such surgical interventions would not be possible without anesthesia. This technique was originally introduced for the surgical treatment of epilepsy and has subsequently been used in patients undergoing surgical management of supratentorial tumours, deep brain stimulation and near critical brain regions. This surgical approach aims to maximize lesion resection while sparing important areas of the brain.
