Endoscopic pituitary surgery has definite advantages over the traditional method using the operating microscope. Improved visualization, angled view, and a wider panoramic perspective of the important anatomic relationships of the sphenoid and the sella turcica were the obvious advantages. The direct endonasal transsphenoidal approach is the most minimally invasive. Its advantages include wider access, avoidance of a septoplasty, and the ability for two surgeons to work together enabling better instrumentation and more complete and rapid removal of the tumor.
