Frontolateral transfalcine approach to olfactory groove meningioma: rationale for surgical selection. Two-dimensional...

Area of Science:

• Neurosurgery
• Skull Base Surgery
• Neuro-oncology

Background:

• Olfactory groove meningiomas pose significant surgical challenges due to their location near critical brain structures.
• Preserving olfactory function and minimizing neurological deficits are key goals in managing these tumors.

Purpose of the Study:

• To present a microsurgical technique for olfactory groove meningioma resection.
• To highlight the safety and efficacy of the right frontolateral approach for anterior skull base meningiomas.

Main Methods:

• Demonstration of a stepwise microsurgical resection of an olfactory groove meningioma.
• Utilizing a right frontolateral approach to achieve a wide operative corridor.
• Focus on early tumor devascularization and anatomical preservation of olfactory tracts.

Main Results:

• The right frontolateral approach provides excellent surgical access with minimal frontal lobe retraction.
• The technique allows for early devascularization and preservation of contralateral olfactory tract anatomy.
• The presented approach emphasizes safety and anatomical considerations for olfactory function.

Conclusions:

• The right frontolateral approach is a safe and effective method for selected olfactory groove meningiomas.
• This technique facilitates the preservation of olfactory function in anterior skull base tumor surgery.
• Microsurgical anatomical details and surgical pearls are crucial for successful outcomes.
