[Delayed traumatic CSF-fistulas: a retrospective analysis].
Immediate posttraumatic CSF-fistulas are a well known entity after severe head injury. Delayed onset of rhinorrhea is considered to be rare. In the last 5 years 7 patients were treated in our department, who developed rhinorrhea 2-25 years after trauma. All patients went through episodes of meningitis. In 4 cases intermittent rhinorrhea was reported. In all cases a bony defect of the anterior skull base was detected by coronal bone window CT-scan. In three of them an encephalocele was revealed by MR-scanning. Treatment consisted in reconstruction of anterior skull base with a pedicled galeal-pericranial flap via a bifrontal craniotomy and went out without any complications. Delayed rhinorrhea after severe head injury is not a rare curiosity. In cases of bony defects after head injury reconstruction of anterior skull base is recommended to prevent episodes of recurrent meningitis.
