title: Relationships between portions of the third and fourth ventricles. An aid to stereotactic accuracy for posterior fossa stereotaxy.
abstract: The relationships between the third and fourth ventricles have been studied by examination of the angles formed by third and fourth ventricular projections. These have been subjected to statistical analysis and have proved useful for posterior fossa stereotactic surgery.
