The Supracerebellar Suprapineal Approach: A Novel Method to Separate Cadaveric Brain Hemispheres and Preserve the Midline Structures.

Objectives: To describe a novel technique for dissecting cadaver brains without damaging medial brain structures and surfaces, ensuring preservation for neuroanatomical study and training.

Methods: Ten adult cadaveric brains were dissected using the supracerebellar suprapineal approach under an operative microscope with 6x to 40x magnification. This approach allowed for the separation of the brain into two hemispheres while providing direct visualization of the third ventricle and preserving midline structures.

External Auditory Canal Transillumination-Guided Middle Fossa Approaches: An Anatomical Feasibility Study.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Virtual anatomical atlas of the deep brain nuclei.

This study aims to improve understanding of the anatomy of the deep brain nuclei relevant to deep brain stimulation as well as stereotactic lesioning procedures, including radio frequency, high-focused ultrasound, and radiosurgery. We created interactive, three-dimensional virtual models from cadaveric dissections and radiological segmentation. We used five brain specimens (ten hemispheres) obtained from routine autopsies, prepared according to Klingler's method.

Comparative Assessment of Thermal Damage Induced by Bipolar Forceps in a Bovine Liver.

Background And Objectives: Bipolar electrocautery systems in neurosurgical procedures may induce thermal damage to adjacent tissues, especially neural tissues. Therefore, it is crucial to control thermal spread from the tips of bipolar forceps into adjacent tissues. The goal of this study was to compare the thermal damage induced in unintended adjacent tissues during coagulation with 6 different bipolar forceps.
