Application of autologous fibrin glue for skull base defect closure in transsphenoidal surgery. Case report and literature review.

Nasal CSF leakage is the most common complication after transsphenoidal surgery, especially in case of extended transsphenoidal access. It is one of the main and obvious risk factors of meningitis. Introduction of effective reconstructive techniques made it possible to reduce the incidence of postoperative CSF leakage. Fibrin glue is one of the main components in transsphenoidal surgery for skull base defect closure. The use of autologous fibrin glue excludes immune response due to its biocompatibility. Modern technologies of preparation of autologous fibrin glue make it possible to obtain a large volume of glue that ensures complete sealing of skull base defect. At the same time, autologous glue contains factors promoting rapid tissue regeneration. It is of great importance for engraftment of autologous transplants in the area of skull base defect.
