title: Stereotaxic device for polar approaches in orthogonal systems. Technical note.
abstract: A special stereotaxic device is described which was conceived and built to integrate the peculiar orthogonal approach of the well known Talairach apparatus with a polar approach. The device is useful to reach small and deep-seated brain targets, particularly those located on or close to the midline. Its use in several different stereotaxic operations, such as thalamotomy, brain-tumor biopsy, or radiotherapy, proved its flexibility, safety, and reliability.
