hi desiree,
welcome to hcm
thanks for the query
since you accident was 4 yr back its unlikely to be the fluid is leaked csf
but you can once confirm it by consult it with a otorhinolaryngologist
it may be due to some other causes like rhinitis
take care

1. You should try and collect this fluid in a sterile container if it happens again and get it examined to rule out CSF (Cerebro Spinal Fluid). Get a Beta-2 Transferrin test on the fluid, if available.

2. Your symptoms are similar to the 'teapot' sign or 'reservoir sign', where this fluid drips out on bending forwards or looking down. Were you just standing or had you bent your head forwards or down? Had you coughed or strained just before this episode?

3. A simple test is the 'Handerchief Test': Normal nasal secretions contain mucus which will stain and stiffen a soft handkerchief on drying, but CSF will not.

4. If the above mentioned tests are negative, then you have allergic rhinitis.

5. If CSF leak is suspected, a CT cisternography and MRI with contrast should be done.

6. This is by no means an exhaustive investigation. Further testing depends upon the results (of these above mentioned tests) that you may post here.

7. If you have confirmed CSF rhinorrhea, the treatment remains the same, irrespective of the cause.

8. An endoscopic repair through the nose will be possible with fat, cartilage, fascia and fibrin glue.
