Endonasal Surgery

Endonasal Surgery is intracranial surgery through a nostril using the operating microscope or endoscope or both. Endonasal surgery is a subset of transsphenoidal surgery which means operating through the sphenoid sinus (behind the nasal cavity). Virtually all pituitary adenomas and Rathke’s cleft cysts, the majority of craniopharyngiomas and clival chordomas as well as many other tumor types such as suprasellar meningiomas and sinus carcinomas can now be removed through a nostril.
