MENINGIOMAS
OVERVIEW
A meningioma is a noncancerous and slow-growing tumor that develops in the covering of the brain (meninges). Small meningiomas and those without symptoms can be observed with periodic MRI imaging to monitor tumor growth. The optimal treatment for the great majority of symptomatic or growing meningiomas is maximal safe surgical removal. The selection of the type of surgical approach depends very much on the tumor location.
SKULL BASE MENINGIOMAS
Skull base meningiomas are the most challenging as they arise from the lining at the base of the skull where they are intimately related with critical nerves and vessels. It is extraordinarily important that these tumors are treated by very experienced surgeons with expertise in advanced skull base surgery techniques.
ENDOSCOPIC ENDONASAL APPROACH
The endoscopic endonasal approach (EEA) for treating meningiomas has unique advantages over traditional surgery:
1-Minimally Invasive Surgery:
The EEA uses the nostrils and nasal cavity as a natural corridor to the base of the skull, avoiding the need for skin incisions and cranial openings.
2-Early Tumor Devascularization:
The vascular supply to the tumor originates mostly from the base of the skull, and using the EEA, it can be interrupted before entering the tumor.
3-Direct Access to Tumor Origin:
The EEA provides direct access to the tumor origin without any manipulation of the brain, vessels, or cranial nerves.
4-Minimizing Complications:
A less invasive but more direct access with no manipulation of neural structures and early tumor devascularization produces better clinical results with shorter recovery times.
