Although the methods by which a previously performed craniotomy can be reopened for posterior callosotomy have already been reported, posterior corpus callosotomy using a parietooccipital interhemispheric approach with the patient in a semi-prone park-bench position has not been described in the literature. Here, the authors present a surgical technique for posterior callosotomy using a parietooccipital interhemispheric approach with a semi-prone park-bench position as a second surgery. Although this procedure requires an additional skin incision in the parietooccipital region, it makes the 2-stage callosotomy safer and easier to perform because of reduced intracranial adhesion, less bleeding, and an easier approach to the splenium of the corpus callosum.<\/jats:p>","DOI":"10.3171\/2014.12.jns141732","type":"journal-article","created":{"date-parts":[[2015,6,5]],"date-time":"2015-06-05T14:06:53Z","timestamp":1433513213000},"page":"1322-1325","source":"Crossref","is-referenced-by-count":6,"title":["Posterior
