Our current understanding of pituitary tumors is quite deep, and we have accumulated rich treatment experience in the pathogenesis, disease progression, and treatment of pituitary tumors. Therefore, it is recommended to use surgical methods for pituitary tumor patients, especially those with obvious symptoms. Clinically, it is generally recommended to choose the transnasal-transsphenoidal approach for a complete resection of the pituitary tumor. For most patients, this can achieve good therapeutic effects. Moreover, with the continuous advancement of diagnostic techniques, early detection and treatment of small early pituitary microadenomas through complete surgical resection can also achieve good therapeutic outcomes.
