Tuberculum Meningioma: Orbitopterional Approach

Area of Science:

• Neurosurgery
• Neuro-oncology
• Ophthalmology

Background:

• Tuberculum sella meningiomas can cause significant visual impairment due to their location.
• Extensive tumors involving the circle of Willis pose surgical challenges.

Purpose of the Study:

• To describe a surgical approach for extensive tuberculum sella meningioma.
• To highlight the preservation of neurovascular structures during resection.

Main Methods:

• A right orbitopterional approach was utilized for tumor access.
• Ultrasonic aspiration and sharp dissection were employed for tumor debulking.
• The surgical strategy involved multiple windows for tumor removal and optic nerve decompression.

Main Results:

• Gross total resection of the tuberculum sella meningioma was achieved.
• The circle of Willis and its perforators were preserved.
• Postoperative improvement in vision and resolution of third nerve palsy were observed.

Conclusions:

• The orbitopterional approach is effective for extensive tuberculum sella meningiomas.
• Meticulous surgical technique ensures preservation of critical neurovascular structures.
• Successful resection leads to improved visual outcomes and neurological function.
