Comparison of endoscopic vs microsurgical resection of pituitary adenomas with parasellar extension and evaluation of the predictive value of a simple “4 quadrants” radiological classification
The amount of parasellar extension is a known limitation for gross total resection (GTR) of pituitary adenomas. Endoscopic technique seems to improve resection of adenomas extending laterally. Knosp classification is used to evaluate the extent of parasellar invasion: at increasing Knosp grades correspond lower rate of GTR. The “4 quadrants” method could help to estimate the risk of partial resection in adenomas with parasellar extension.
