| ABSTRACT |
OBJECTIVE
Suprasellar meningioma have in general been difficult lesions to treat because of their vicinity to the optic apparatus and major vessels, and high vascularity.
This study was performed to analyze clinical outcome of patients with histopathologically identified suprasellar meningioma.
METHOD
Between 1989 and 1998, 37 patients(30 women, 7 men: average 47.5years) with histopathologically identified meningiomas originating from the suprasellar region underwent surgical tumor removal in our institution. The medical records and clinical data of these patients are retrospectively analyzed.
RESULT
The tumor size ranged from 2.1cm to 6.5cm(average 5.1cm) in diameter. The tumors have been approached basically through the pterional and bifrontal routes. Skull base technique was also applied in large or complicated cases. Total resection rates and overall outcome including visual function was better in patients with tumor of less then 3cm. A considerable increase of mortality, morbidity and failure of visual improvement were seen in case of the tumors size of 3cm or more.
CONCLUSION
Early diagnosis and treatment were important factors in the successful management of these suprasellar meningioma. In large complicated cases encasing major vessels or invading cavernous sinus or anterior skull base, surgeons need to operate with extreme caution and piecemeal removal of the tumor without injuring optic apparatus and major vessels utilizing skull base technique. |
