Craniopharyngioma is a benign congenital tumor with peak incidence in adolescence and middle age. Patients often have headache, dizziness, nausea, vomiting and other symptoms, and are often accompanied by decreased visual field. For the treatment of craniopharyngioma, the current consensus is that total surgery can achieve a more desirable clinical outcome, while patients who fail to undergo total excision need to combine radiotherapy to control tumor recurrence. Factors affecting the prognosis: 1. The growth nature of the tumor itself and its size as well as the relationship with the surrounding structures. Craniopharyngioma is a kind of tumor with relatively high recurrence rate and has calcification. If it has close relationship with surrounding tissues and blood vessels, it is difficult to cut it completely. The clinical experience of the surgeon, the first operation to completely cut the tumor will lay a good foundation for the prognosis, while the clinical effect of the second or multiple operations is relatively poor.
