Transcallosal approach (neurosurgery)
Interhemispheric transcallosal approach is a common access route for surgery on the bodies of the lateral ventricles, and third ventricle, which does not lead to serious neurological deficits. It is therefore used for resection of intraventricular tumors such as:
The advantages of using a transcallosal approach over a transcortical approach include a direct midline orientation with symmetrical access to both lateral ventricles and both walls of the third ventricle. Therefore, violation of the cerebral cortex and the risk of postoperative seizures can be avoided 2.
