Intraoperative CSF Leak Identification And Repair


  • CSF leak occurring during sinus surgery
  • Clear rhinorrhea following sinus surgery


  • Edges of skull base defect identified and freshened
  • Free mucosal graft from septum or turbinate placed over defect
  • Graft held firmly in place with absorbable packing material

Keep in Mind/Things to Remember:

  • Most intraop leaks can be successfully closed with one-layer repair.
  • A non-absorbable packing material may be placed for a one-week period of time in order to further bolster the repair site.
