Transplanum polare approach to the anterior mesiotemporal region.

BACKGROUND

The transplanum polare approach is a surgical technique targeting mesiotemporal structures, such as the amygdala and hippocampus. It offers a safer alternative to transcortical and transsylvian routes, reducing risks to white matter tracts, optic radiations, and vascular structures.

METHOD: This method involves a pterional craniotomy with tailored sylvian fissure dissection to access the planum polare. Dynamic retraction, image guidance, and subpial dissection ensure precise resection while preserving critical neural and vascular anatomy.

CONCLUSION

By minimizing disruption and technical complexity, the transplanum polare approach enhances safety and efficacy, reducing complications and improving outcomes for patients with mesiotemporal lesions.
