RESUMO

Objective: Using a fiber-dissection technique, our aim is to study the fiber bundles of the optic radiation. We focused on the course, the length, anatomical relations with lateral ventricle and the relevance of these finding during surgery in the region. Materials and Methods: Five previously frozen and formalin-fixed cadaveric human brains were used. The dissection was done using the operating microscope. Fiber dissection techniques described by Klingler were adopted. The primary dissection tools were handmade, thin, and wooden and curved metallic spatulas with tips of various sizes. Lateral and inferior temporal approaches were made and the optic fiber tracts were dissected. Results: Resections that extend through the roof of the temporal horn more than 30 mm behind the temporal pole cross the Meyer's loop. In the middle temporal gyrus approach, resection that is taken through the lateral wall of the temporal horn more than 55-60 mm behind the temporal pole may cross the optic radiation during their course here on the lateral wall. Conclusion: The presented fiber dissection study clarifies the relationship of optic radiation. Such fiber dissection studies are only few in the literature.

RESUMO

The techniques of craniovertebral region stabilization introduced and used by the senior author over the last 20 years are summarized. The lateral masses of atlas and axis are strong and largely cancellous in nature and can be used for direct implantation of screws. Opening up of the joint and placement of bone graft within the joint stabilizes the region and provides a large area for bone fusion. Distraction of the facets provides an opportunity to treat a range of congenital craniovertebral anomalies. The technique of exposure of the lateral mass of the atlas and axis and the atlantoaxial joint is technically relatively complex and needs precise understanding of anatomy of the vertebral artery and training with cadavers.
