NASAL LIQUORRHEA AND LUMBAR DRAINAGE AFTER REMOVAL OF TUMORS OF THE CHIASMAL-SELLAR REGION
Surgery of tumors of the chiasmal-sellar region is one of the most urgent problems of modern surgery. At the current level of development of endoscopic technique, the most actively used endoscopic endonasal transsphenoidal tumor removal. This method is the least traumatic, better tolerated by patients and is characterized by a lower incidence of complications. However, even this surgical access is not devoid of certain drawbacks. Since the first attempt to remove the tumor by transsphenoidal access, one of the most important tasks has been to create an effective recovery of the cell floor for the prevention of postoperative liquorrhea and meningitis. Nasal liquorrhea is a fairly common condition in transsphenoidal interventions. It is a feature of this type of surgery and is characterized by a fairly high frequency in both intra - and postoperative period. Liquorrhea is considered an extremely dangerous and serious condition due to the threat of infection of the liquor system and the development of secondary meningitis. Lumbar drainage is one of the methods used to prevent the growth of intracranial hypertension and the treatment of nasal liquorrhea in patients operated on for tumors of the chiasmal-sellar region. The use of this method is not mandatory and is used depending on the approaches taken in a particular medical organization. The different frequency and risks of lumbar drainage after these surgeries are described.
