Pituitary tumors are common, accounting for 10-15% of all primary brain tumors, with a high incidence in the 30-60 age group. In the incidence population, functional pituitary tumors are common in young people, while the incidence of non-functional pituitary tumors increases with age. The main clinical manifestations of pituitary tumors are endocrine dysfunction and symptoms caused by occupational effects, including: headache; hypermetropia and bilateral temporal hemianopia; amenorrhea, lactation and infertility in female patients, and hypogonadism, impotence and thinning of body hair in male patients; and acromegaly.
At present, the surgical treatment of pituitary tumor mostly adopts: 1) microscopic transsphenoidal approach pituitary tumor removal; 2) endoscopic transsphenoidal approach pituitary tumor removal; 3) open frontal or pterygoid approach pituitary tumor removal.
