corpus callosotomy
Pronunciation: KOR-pus kal-oh-SOT-oh-mee
Surgical division of the corpus callosum to treat certain types of intractable epilepsy or remove callosal tumors.
Full Definition
Corpus callosotomy is a neurosurgical procedure involving sectioning of the corpus callosum, the major white matter tract connecting the cerebral hemispheres. In epilepsy surgery, partial or complete callosotomy is performed for drop attacks and generalized seizures that cannot be controlled medically. In tumor surgery, callosotomy may be required when neoplasms infiltrate or compress the corpus callosum. The procedure can result in disconnection syndrome, characterized by difficulty transferring information between hemispheres, though patients often adapt well over time.
Usage
Usage note: Specify whether anterior, posterior, or complete when documenting the procedure.
