=====Transventricular approach=====
The [[transventricular approach]] through a [[transcortical approach]] or a [[transcallosal approach]] allows access to the [[third ventricle]] with transforaminal, subchoroidal, or transfornician approaches. The usefulness of these approaches have been reported for intraventricular tumor removal
((Chamoun R, Couldwell WT. Transcortical-transforaminal microscopic approach for purely intraventricular craniopharyngioma. Neurosurg Focus. 2013;34(1 Suppl) Video 4.))
((Danaila L, Radoi M. Surgery of tumors of the third ventricle region. Chirurgia (Bucar) 2013;108:456–62.))
((Liu JK. Interhemispheric transcallosal approach for resection of intraventricular central neurocytoma. Neurosurg Focus. 2013;34(1 Suppl) Video 3))
((Tomasello F, Cardali S, Angileri FF, Conti A. Transcallosal approach to third ventricle tumors: How I do it. Acta Neurochir. 2013;155:1031–4))
but there is a risk of injuries to the surrounding neuronal or vascular structures, such as the body of the [[fornix]].

In [[1958]], Niemeyer described a more selective [[approach]] to the [[hippocampus]] and [[amygdala]] through the [[middle temporal gyrus]]
((Niemeyer P, Baldwin M, Bailey P. The [[transventricular]] [[amygdala]]-[[hippocampectomy]] in [[temporal lobe epilepsy]]. In: Temporal Lobe Epilepsy. Springfield: Charles C Thomas; 1958:461–482)).
