The object of study - tumors of the skull base of chiasmal-selar localization. Objective: To improve the results of surgical treatment of patients with tumors of the chiasmal-selar localization. Tumors of chiasmal-selar localization make about 15-20% of all intracranial tumors. Pituitary adenomas occur in 10-15% of cases. The anatomical feature of this area determines the complexity of treatment of this pathology. Endoscopic endonasal transsphenoidal method is an effective method of surgical treatment of both pituitary adenoma and other pathologies of celery localization. Due to the anatomical features of the chiasmal-cellular region and the cavernous sinus, changed in the presence of the spread of tumors in the latter, the safety of surgery is relevant. Given the significant variety of tumors in the chiasmal-selar region that affect the slope of the main bone and spread laterally and to the posterior cranial fossa, tumors that spread within the anterior cranial fossa, the choice of adequate endonasal dilated access is a difficult question. The invasiveness of cranial base tumors increases the risk of intraoperative and postoperative complications and the possibility of improving the technique of endoscopic endonasal extended access is relevant. In invasive tumors of the skull base, the totality of removal may not always be achievable and is most often observed in meningiomas of the rhino-olfactory fossa, the site of the main bone, the hill of the Turkish saddle, petro-cleft meningiomas. The frequency of total and subtotal removal of tumors of the skull base is achieved in 17-74%, and mortality can reach 4%, and complications in 9%. Relapses are up to 27%, remission is observed in 69.1%. Product Description popup.authors Aksonov Ruslan V Vasyuta Vira A Huk Andrii P.
