Modern principles of endoscopic transnasal reconstruction of skull base defects Literature review

Cerebrospinal fluid (CSF) leak is an urgent problem of modern neurosurgery. In elective surgery, this condition is most commonly encountered in the removal of skull base tumors. The reconstruction stage is the final stage in the course of such operations and directly affects the postoperative period of the patient. Due to advances in technology, a number of techniques that allow for hermetic closure of the intracranial space have now been developed. The most significant was the introduction of vascularized flaps, which reduced the incidence of liquorrhea many times over. This paper presents the current trends in this section of neurosurgery.
