Abstract

Introduction
Substantial evidence supports the notion that venous outflow abnormalities and obstructions serve as a common underlying mechanism in the pathogenesis and perpetuation of intracranial hypertension, as well as the subsequent development of CSF rhinorrhea. Although both dural venous sinus stenosis (DVS) and spontaneous CSF rhinorrhea have each been independently linked to IIH, there is a paucity of evidence directly linking DVS with spontaneous CSF rhinorrhea. Spontaneous CSF rhinorrhea, characterized by an abnormal communication between the subarachnoid space and the nasal cavity, is increasingly recognized as a variant of IIH. This study investigates the role of DVS in the pathogenesis of these conditions, focusing on its prevalence and correlation with recurrence after endoscopic repair of CSF leaks.

Aims
1. Compare the prevalence of DVS in three groups: patients with idiopathic CSF rhinorrhea, patients with IIH, and healthy controls.
2. Examine the correlation between DVS and recurrence rates following endoscopic repair of CSF rhinorrhea.
