Sphenoid and sellar tumors.

The management of tumors of the sphenoid sinus and sellar-parasellar region has experienced dramatic conceptual and technical advances over the past two decades. Malignant lesions and benign invasive lesions, once carrying a dismal outlook and deemed inoperable, are now being adequately circumscribed and resected with good results. The formation of skull base teams throughout the world and the widespread concept of a multidisciplinary approach to skull base tumors has led to advancements in the treatment of sphenoid and sellar-parasellar tumors.
