What is the surgical procedure called that severs the corpus callosum to reduce seizure spread?

• A. Callosotomy
• B. Commissurotomy
• C. Corpus callosotomy
• D. Transcallosal disconnection

Answer: (C)

Seizure activity often travels between the brain’s two hemispheres through the corpus callosum, so cutting that bridge can limit how widely seizures spread. The procedure that severs the corpus callosum to reduce seizure spread is called corpus callosotomy. By interrupting this main interhemispheric pathway, many patients with severe, drug-resistant epilepsy see a decrease in generalized seizures. Surgeons may perform a partial callosotomy to balance seizure control with preserving some interhemispheric communication, with the option to extend the disconnection if needed. While callosotomy is a common shorthand, corpus callosotomy specifies the exact structure being cut. Commissurotomy or transcallosal disconnection describe related ideas or approaches rather than the standard name for this exact operation.
