Posterior callosotomy

A 2-stage corpus callosotomy is accepted as a palliative procedure for patients older than 16 years with, in particular, medically intractable generalized seizures and drop attack seizures and is preferable for a lower risk of disconnection syndrome.

Methods by which a previously performed craniotomy can be reopened for posterior callosotomy have already been reported.

Ito et al. published a surgical technique for posterior callosotomy using a interhemispheric parietooccipital 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 1).
