Temporal lobectomy
Pronunciation: TEM-por-al loh-BEK-toh-mee
Surgical removal of part of the temporal lobe to treat medication-resistant temporal lobe epilepsy.
Full Definition
Temporal lobectomy is the most common epilepsy surgery procedure, involving surgical removal of the anterior portion of the temporal lobe, including the hippocampus, amygdala, and surrounding temporal neocortex. This procedure is typically performed for patients with mesial temporal lobe epilepsy who have failed multiple antiseizure medications. Success rates for seizure freedom are generally high (60-80%), though the procedure carries risks including memory impairment and visual field defects depending on the surgical approach and hemisphere involved.
Usage
Usage note: Specify laterality (left/right) when discussing specific cases; distinguish from selective procedures.
