Corpus callosotomy—Open and endoscopic surgical techniques

Corpus callosotomy is a palliative surgical procedure for patients with refractory epilepsy. It can be performed through an open approach via a standard craniotomy and the aid of an operating microscope, or alternatively via a mini-craniotomy with endoscope assistance. The extent of callosal disconnection performed varies according to indications and surgeon preference. In this article, we describe both open and endoscopic surgical techniques for anterior and complete corpus callosotomy.
