The recurrence rate of pituitary tumor after surgery varies according to the types of pituitary tumors.1, lactogenic adenoma: its recurrence rate after surgery is about 40%.2, growth hormone adenoma: its recurrence rate after surgery is about 13% or less.3, adrenal hormone-producing adenomas: its recurrence rate after surgery is about 6%-25%, for the cases of non-remission and recurrence, those who are still of pituitary origin can be examined and have total pituitary resection by pterotibial exploration. For those cases which are still of pituitary origin after examination, the total pituitary resection can be carried out through the pteropituitary gland again, and good results can often be obtained.4. Pituitary thyroid-stimulating hormone adenomas: the cure rate of simple surgery is about 30%-40%, and the cure rate of comprehensive treatment can reach 50%-70%, and the recurrence rate of these adenomas varies from about 30%-70%.
