*9.1.3 Sellar stage*

After a wide removal of anterior wall of sphenoidal sinus and drilling of sphenoidal septa, sellar floor will be seen. Important anatomical landmarks at sellar floor include carotids, optic nerves, pituitary prominences, and lateral opticocarotid recesses bilaterally (**Figure 2**). Progressive thinning of sellar floor using diamond drill and Kerrison rongeur till the dura over the pituitary gland is exposed. Lateral and superior exposure depends on the extent of the tumor. We prefer not to expose the intracavernous carotids unless the anterior wall of cavernous sinus is needed to be opened for medial wall resection or when dealing with functional adenomas.
