Over the past 20 years, the popularity of transsphenoidal pituitary tumor resection, the transcranial operation ratio gradually decreased, but due to pituitary tumor growth and propagation direction, the two approach is hard to replace each other and each has its value of existence. The adaptation includes cranial surgery syndrome: suprasellar extension to the height of the tumor; giant pituitary tumor development and to the sella do not expand on the saddle: on the sella tumor growth: dumbbell tumor, saddle forward cranial fossa growth; saddle phyllodes tumor. The advantages of transcranial operation are as follows: good vision, fully exposed, reached the frontal, side of oculomotor nerve and cavernous sinus, issued after the interpeduncular fossa, up to the third ventricle in endplate surgery under the microscope operating room; the complete resection of the tumor; the protection of skull base vessels and optic nerve and hypothalamus, pituitary handle and other important structures, minimizing the blind; the tumor was especially well suited to the saddle and saddle outside the elderly. The disadvantages of the operation of the skull: the operation is large, the bleeding is more, the recovery is slow and it is easy to damage the structure of the optic chiasm and the internal carotid artery.
