Surgical Repair of Cerebrospinal Fluid Rhinorrhea: Report of Five Operative Cases

This report describes five cases of cerebrospinal fluid(CSF) rhinorrhea which were caused by head injury in four cases and developed after surgical removal of brain tumor in one case. Intrathecally-enhanced brain computerized tomography(CT) with metrizamide, in addition to isotope cisternography, was helpful in localization of the CSF leakage site. All five cases which could not be managed conservatively were successfully repaired by surgical means using biological fibrin glue.
