AbstractCorpus callosotomy is among the oldest surgeries performed for drug-resistant epilepsy. Since it was first performed in 1940, numerous studies have assessed its outcomes in various patient populations in addition to describing different extents of sectioning and emerging technologies (i.e., endoscopic, laser interstitial thermal therapy, and radiosurgery). To capture the current state and offer a reappraisal, we comprehensively review the origins of corpus callosotomy, efficacy for various seizure types, technical variations, complications, and indications and compare the procedure with vagus nerve stimulation therapy, which has similar indications. We consider corpus callosotomy to be a safe and efficacious procedure, which should be considered by clinicians when appropriate. Furthermore, it can play an important role in treating patients with drug-resistant epilepsy when appropriate in low-to-middle-income countries where resources are limited.Copyright © 2022 Elsevier Inc.
