Treatment of pituitary adenomas consists of two types of treatment: surgical and pharmacological. At present, most pituitary adenomas require surgical treatment, and there are two types of surgery: transnasal pterygoid sinus approach and transfrontal craniotomy. 1.Transnasal pterygoid approach: At present, about 95% of pituitary adenomas are removed by transnasal pterygoid approach. The indications for transnasal pterygoid surgery are: (1) various types of pituitary microadenoma; (2) various types of pituitary macroadenoma; (3) various types of pituitary giant adenoma (maximum diameter >3.0cm, such as the main extension to the suprasellar or posterior suprasellar, mildly to the anterior and mildly to both sides of the suprasellar. For advanced giant tumor invading the cavernous sinus or even involving the cavernous sinus invading the middle cranial fossa, a partial or partial resection can be performed via the butterfly to improve the vision and prepare for the second stage of craniotomy); (4) those with visual cross front; (5) those with tumor growing to the pterygoid sinus, growing backward to invade the saddle back and slope, and cerebrospinal fluid nasal leakage. 2.Craniotomy treatment: It is mainly transfrontal approach surgery. It accounts for only 5% of pituitary adenoma surgery. Transcranial approach is suitable for: tumors that grow towards the suprasellar, paracranial, inferior frontal and slope. Drug therapy: Primarily for female pituitary lactogenic microadenomas with fertility requirements. For pituitary growth hormone adenoma, pituitary pro-adrenal hormone adenoma and pituitary non-functioning adenoma, there are no definite therapeutic drugs. Therefore, for these three types of pituitary adenomas, pharmacological treatment is not clinically recommended.
