[Results of fluorescein nose endoscopy in the diagnosis of cerebrospinal rhinorrhea].

To establish the diagnosis of cerebrospinal rhinorrhoea 45 patients were examined via intrathecal fluorescein-dye studies. Rhinorrhoea was suspected after head injuries and surgery of the base of the skull. The diagnostic procedure was in accordance with the technique of Messerklinger. In 8 patients a fluorescent secretion was detected and a CSF-leakage operatively proven. The result of the fluorescein tests, the x-ray tomographies and the RIHSA-studies are compared. The fluorescein technique is shown to be a useful diagnostic tool in the diagnosis of cerebrospinal leaks.
