Introduction: The exact pathophysiology of spontaneous CSF rhinorrhea is\nnot always understood in some patients.

Methods:\nWe prospectively managed patients with spontaneous CSF rhinorrhea\nwho were admitted to our hospital between 1st of January 2014 and 31st of\nDecember 2017 with a prespecified treatment algorithm.
