Transplanum polare approach
The transplanum polare approach is a neurosurgical 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.
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.
By minimizing disruption and technical complexity, the transplanum polare approach enhances safety and efficacy, reducing complications and improving outcomes for patients with mesiotemporal lesions 1).
The transplanum polare approach represents a promising and anatomically respectful alternative for anterior mesiotemporal access. Its strengths lie in its minimally disruptive trajectory and alignment with modern microsurgical philosophies. However, the article would benefit from more comprehensive outcome data, comparative analysis, and a discussion of practical limitations. Future work should focus on multicenter validation, standardized patient selection, and long-term functional outcomes to establish this technique as a reliable alternative in mesiotemporal surgery.
