Article Synopsis
- The study aimed to compare two surgical approaches to the atrium of the lateral ventricle by using white matter fiber dissections and MR tractography for better anatomical understanding.
- Researchers dissected ten cerebral hemispheres, focusing on the white matter tracts connected to the atrium while also correlating findings from MR tractography with cadaver dissections.
- The findings revealed specific relationships of white matter tracts to the atrium and indicated that the posterior interhemispheric approach is safer for minimizing risk to key tracts, although some tracts are still inevitably affected during this approach.
Introduction: The bifrontal transbasal approach is an anterior midline skull base approach to anterior skull base, sellae region and, if needed, to posterior skull base in the midline, often used for tumoral lesions but also useful for vascular or infectious pathologies.
Methods: Descriptive anatomic study, 5 formalin-fixed human cadaveric heads were used injected with colored silicone. The dissection was made step-by-step to describe every anatomic structure encountered.
Objective: To analyze the three-dimensional relationships of the operculoinsular compartments, using standard hemispheric and white matter fiber dissection and review the anatomy of association fibers related to the operculoinsular compartments of the Sylvian fissure and the main white matter tracts located deep into the insula. The secondary aim of this study was to improve the knowledge on this complex region to safely address tumor, vascular, and epilepsy lesions with an integrated perspective of the topographic and white matter fiber anatomy using 2D and 3D photographs.
Methods: Six cadaveric hemispheres were dissected.
