Fluid leaking from the nose or external auditory canal must first be positively identified as CSF. Drops of fluid from a CSF leak placed on absorbent filter paper may result in the double-ring sign, which is a central circle of blood and an outer clear ring of CSF. Results of glucose, ...
A case of cerebrospinal fluid rhinorrhea is presented in which routine diagnostic evaluation failed to disclose the site of leakage. Computerized tomography (CT) scanning with metrizamide, a nonionic contrast medium, provided not only documentation of the leak but also demonstrated the actual sinus ...
When there is a tear or hole in the dura mater of the brain, it is known as acranial CSF leak. This causes CSF to leak into the sinuses (two sets of cavities in your head) and out through the nose. This is different from a spinal CSF leak, in which the fluid leaks from the sp...
Another sign of a CSF leak is constant drainage of a clear fluid from the nose and ears, especially with any sort of head movements like bending forward. Some people also complain of a metallic taste in the mouth. Ringing in the ears is also sometimes noticed in people with a CSF leak....

V E was measured with a noseplece and a screen flowmeter. CSF samples were taken before and 7 min after continuous breathing of O 2 . Results: All values: Mean ± S.E. These findings suggest that hyperventilation with 100% O 2 is associated with a decrease in alveolar and CSF PCO 2 ...
A rare case of cerebrospinal fluid leak occurred after a tester inadvertently swabbed a previously unidentified encephalocele during nasal swab testing for COVID-19.
Cribriform plate is the commonest site of Cerebrospinal fluid (CSF) leak, its fragility and juxtaposition of arachnoid’s investment to the bone, where the olfactory nerve pierces the skull, is a vulnerable site for CSF leak. Endoscopic transnasal approach has been the main stay for CSF leak ...
Cerebrospinal fluid (CSF) leaks associated with endoscopic sinus surgery (ESS) are a rare complication related to anatomical and technical factors. The anatomical variations at skull base level are imperative to be detected preoperatively by CT scan to avoid this complication. Identifying the factors ...
Transnasal endoscopic repair of cerebrospinal fluid rhinorrhea and skull base defects: a review of twenty-nine cases. The management of has historically plagued the neurosurgeon and the otolaryngologist-head and neck surgeon. Intracranial repair is still favored at many in... EE Dodson,CW Gross,JL...
