Background <p>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.</p> Method <p>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.</p> Conclusion <p>By minimizing disruption and technical complexity, the transplanum polare approach enhances safety and efficacy, reducing complications and improving outcomes for patients with mesiotemporal lesions.</p>
