An algorithm for the management of CSF rhinorrhoea illustrated by 36 cases

Abstract

The diagnosis of cerebrospinal fluid (CSF) rhinorrhoea should be established beyond reasonable doubt before surgical intervention is embarked upon. It is important not to miss the diagnosis in view of the real potential complication of meningitis if it is left untreated. We describe a management algorithm which centers around the selective use of nasal endoscopy, immunofixation of beta2 transferrin, high resolution coronal CT scans, and fluorescein lumbar puncture. This management strategy is illustrated with 36 cases. We have developed a minimally invasive endoscopic technique to repair CSF leaks, and in 30 patients we had a success rate of 93% after one procedure.
