ENDOSCOPIC TRANSNASAL REPAIR OF CEREBROSPINAL FLUID LEAKS IN THE AREA OF THE PARANASAL SINUSES AND CLIVUS

5 patients who presented with CSF leaks between the years 2002-2009 were evaluated according to the etiology of the leak. An active CSF leak was confirmed in all patients and the site identified. A repair was planned using either vascularized septal mucosal flaps or free grafts of nasal mucosa. Preparation of the graft recipient site is important. A tissue glue either Tisseal or in the later cases Duraseal held the graft in place and assisted in sealing the leak. The patients were followed for 3 to 5 years to determine if the leak was successfully sealed.
