ABSTRACT

The cerebrospinal fluid rhinorrhoea is rare like a cause of a nasal discharge; it indicates a communication between the noise and the subarachnoid space, it is more commonly traumatic and it is the result of the rupture of the arachnoid and dura mater, elevation of the pressure of cerebrospinal fluid or an osseous defect.
The spontaneous cerebrospinal fluid rhinorrhoea, occurs in 3 to 4% of the cases; in 55% the pressure of the cerebrospinal is normal and it is elevated in 45%.
The osseous architecture of the base of the skull has a great importance in the development of fistulas of CSF. The osseous defects are due to the slimming and weakness of the natural barrier; it could be considered like a congenital anormaly. The cribriform area is recognized like the potentially weakest.
The mechanism that precipitates the apparition of fistulas de CSF isn’t clear.
Objective: demonstrate that the intracranial hypertension idiopathic is a etiologic factor of the development of the spontaneous nasal CSF leak. Material and methods: there were studied 8 patients with the diagnostic of de fistula of CSF in the Neurosurgery and Neurology National Institute, realizing the lumbar puncture for the measurement of the intracranial pressure. Results: the studies reported that the 28.57% of the patients presented IIH.
