Pituitary adenoma is a common benign tumor with an incidence of 1 per 100,000. It mainly harms human body from the following aspects: 1. Excessive secretion of pituitary hormones causes a series of metabolic disorders and organ damage; 2. Tumor compression makes other pituitary hormones low and causes low function of corresponding target glands; 3. Compression of structures in the pterionic saddle area, such as optic cross, optic nerve, cavernous sinus, basilar artery, hypothalamus, third ventricle, and even involves frontal lobe, temporal lobe and brainstem, leading to serious impairment of corresponding functions.
It has serious damage to the patient’s growth, development, labor ability and fertility, and causes a series of psychosocial effects. At present, transsphenoidal microsurgical resection of pituitary adenoma has been widely adopted by neurosurgeons at home and abroad, and is in continuous development. However, craniotomy is still required for pituitary adenomas that develop paracranially, or involve the middle cranial fossa.
