A Stepwise Laboratory Manual for the Dissection and Illustration of Major Limbic Structures. Evidence from the Klingler’s Technique.
Abstract OBJECTIVE: To provide an educational, comprehensive, systematic and stepwise manual for the dissection and illustration of major limbic structures since there is a gap in the pertinent literature. Further, we aim to offer a thorough yet simplified roadmap for laboratory and intraoperative dissections.METHODS: Twenty (20) normal adult, formalin-fixed cerebral hemispheres were studied through the fiber dissection technique and under the microscope. Stepwise and in tandem medial to lateral and lateral to medial dissections were performed in all specimens aiming to reveal the morphology and spatial relationships of major limbic and paralimbic areas RESULTS: Twelve (12) consecutive, discrete and easily reproducible laboratory anatomical steps are systematically described to reveal the intricate anatomy of the structures of the limbic system.CONCLUSION: Surgical approaches for lesions or functional resections in and around limbic areas pose a challenging task for the neurosurgeon. By employing the fiber dissection technique, we were able to provide a stepwise and thorough laboratory guide for the gradual dissection and better comprehension of the morphology and spatial relationships of this specific system. Anatomical manuals like the present study raise interest and enrich anatomical knowledge on complex cerebral areas with the overarching goal to inform surgical practice.
