Endoscopy is commonly used to access which type of tumor?

Explanation:
Endoscopy is well suited for accessing tumors in the sellar region, where pituitary tumors reside. The nasal passages provide a direct route to the sella, so a transsphenoidal endoscopic approach offers a direct, magnified view of the pituitary area, enabling tumor removal or biopsy with less brain retraction and trauma. In contrast, glioblastoma and brainstem glioma are located deep within brain tissue and brainstem, making them unsafe or impractical to reach with this route. Meningiomas can sometimes be approached from skull-base routes, but the classic and most common use of endoscopy is for pituitary tumors.
