Prevention of Cerebrospinal Fluid Rhinorrhea After Transsphenoidal Surgery by Collagen Fleece Coated With Fibrin Sealant Without Autologous Tissue Graft or Postoperative Lumbar Drainage

Abstract

Our technique is an alternative method to the traditional autologous tissue graft technique. PLD is not an essential procedure for the prevention of CSF rhinorrhea if the intraoperative CSF leak is completely sealed off during the transsphenoidal surgery. However, in cases of large arachnoid defects, aggressive repair of the arachnoid defect and sellar floor reconstruction with bone or bony substitutes should be considered in conjunction with our methods.
