Pituitary adenomas sit just above the nasal cavity in the sella turcica, so the preferred way to remove them is through the transsphenoidal route—going through the nose into the sphenoid sinus to reach the sellar region. This path provides direct access to the tumor with minimal manipulation of brain tissue, which translates into fewer complications, less recovery time, and the ability to remove both small and many larger adenomas effectively. Modern transsphenoidal surgery is commonly done with endoscopic or microscopic visualization, which enhances the surgeon’s view of the tumor and surrounding structures, improving safety and extent of resection.

In contrast, opening the skull (craniotomy) exposes brain tissue and generally carries more morbidity, so it’s reserved for cases where the tumor cannot be reached safely from below or has unusual extension. Stereotactic radiosurgery, while useful, is a noninvasive radiation option for selected patients, not a surgical resection. Nasal endoscopic fenestration does not provide reliable access to the sellar region for tumor removal.
