Abstract
Two cases of post-traumatic cerebrospinal fluid rhinorrhea caused by traffic accident were reported. The site of the fistula was the posterior ethmoid cell in the first case, and the frontal sinus in the second. For diagnosis of CSF rhinorrhea, RI counts of the pledgets in the nasal cavity, as well as sagital and coronal tomographies were available. As treatment, a transnasal approach was made, and the fistulae were successfully closed using an operating microscope. The fistulae were sealed by the fascia lata using a fibrin sealant (Tisseel®), and continuous spinal drainage was done pre-and post-operatively.
