Falx Meningioma Vs Parasagittal

Surgical Techniques for Parasagittal Meningiomas

Introduction

Meningiomas are tumors that arise from the meninges, the membranes that cover the brain and spinal cord. Parasagittal meningiomas are a type of meningioma that occurs along the sagittal suture, which is the seam between the two parietal bones of the skull.

Surgical Techniques

There are three main surgical techniques for parasagittal meningiomas:

• Transcranial approach: This approach involves opening the skull to access the tumor. It is the most common approach for parasagittal meningiomas.
• Transdural approach: This approach involves opening the dura, the tough membrane that covers the brain, to access the tumor. It is less common than the transcranial approach.
• Transsylvian approach: This approach involves opening the sylvian fissure, a groove in the brain, to access the tumor. It is the least common approach for parasagittal meningiomas.

The choice of surgical approach depends on the size, location, and extent of the tumor.

Conclusion

Parasagittal meningiomas are a type of meningioma that occurs along the sagittal suture. There are three main surgical techniques for parasagittal meningiomas: transcranial, transdural, and transsylvian. The choice of surgical approach depends on the size, location, and extent of the tumor.
