corpus callosotomy
Pronunciation: KOR-pus kal-oh-SOT-oh-mee
A surgical procedure that involves cutting the corpus callosum to reduce the spread of seizures between brain hemispheres.
Full Definition
Corpus callosotomy is a palliative epilepsy surgery that involves sectioning the corpus callosum, the major fiber bundle connecting the two brain hemispheres. This procedure is typically considered for patients with severe, medically refractory epilepsy, particularly those with drop attacks or generalized seizures that cannot be controlled with medication. The surgery aims to prevent seizures from spreading from one hemisphere to the other, potentially reducing seizure severity and frequency. Complete or partial callosotomy may be performed depending on the patient's specific seizure pattern and risk-benefit assessment.
Usage
Usage note: Distinguish from corpus callosum agenesis, which is a congenital absence of the structure.
