Abstract
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. RESULTS: The supracerebellar suprapineal approach enabled accurate and feasible dissection of the hemispheres without causing damage to the medial brain structures. All midline structures, including the third ventricle, were preserved, producing high-quality specimens for anatomical study. CONCLUSION: The supracerebellar suprapineal approach offers a significant advancement in the technique for hemispheric brain dissection, ensuring the preservation of medial brain structures and providing superior specimens for neurosurgical training and study.
