Abstract

Cerebrospinal fluid (CSF) rhinorrhea usually occurs after a traumatic or non-traumatic head injury, as more than 80% of all cases of CSF rhinorrhea are caused by traumatic head injuries. In fact, CSF rhionorrhea is observed in 2 to 3% of traumatic head injuries, with 50% of the CSF found in the anterior cranial fossa, but mostly of them in the cribriform plate. CSF rhionorrhea can occur two days after a traumatic head injury, but it can take up to 3 months to notice the symptoms of CSF rhionorrhea in a patient with a traumatic head injury. Iatrogenic CSF rhionorrhea is usually caused by neurosurgery operation or otorhinolaryngological surgery such as sinus surgery. For example, closed reduction treating nasal bone fractures can cause CSF rhionorrhea, so patients should be watched at all times. This paper reports two cases of CSF rhionorrhea caused by closed nasal reduction.
