Review[Diagnosis and treatment of frontobasal cerebrospinal fluid fistulas].
Independent of its origin a frontobasal cerebrospinal fluid (CSF) fistula is characterized by an open connection between the intracranial space with the outside world (usually the nose and paranasal sinuses). It leads to loss of CSF and is associated with a significant risk of developing meningitis for the patient during further life. ⋯ Further, laboratory tests to analyse fluid samples for cerebrospinal fluid as well as radiological and endoscopic investigation methods aiming to localize a CSF-fistula are presented. Finally, surgical techniques to close a frontobasal CSF fistula are explained.
