SUMMARY The cerebrospinal fluid leak (CSF leak) is defined as the communication between the subarachnoid space and the upper airway. Can be classified according to their etiology: surgical, traumatic, congenital and spontaneous. The treatment of CSF fistulas can be conservative or surgical. Objective: To describe the experience in the management of cerebrospinal fluid leaks and analyze intranasal endoscopic surgical techniques and surgical results obtained in our service. Materials and Methods: A descriptive, cross-sectional, retrospective study. We included patients with a diagnosis of CSF leak who were treated at the Department of Otolarhinoryngology and Head and Neck Surgery of the Hospital de Clinicas of the Universidad Nacional de Asuncion between March 2008 and December 2012. Results: We reviewed 17 medical records of patients diagnosed with CSF leak between March 2008 and December 2012. The most frequent reason for consultation was watery rhinorrhea in 16 cases. There was a case that consulted form metallic foreign body in the nasal cavity roof. Treatment was conservative in 2 patients. In the remaining 15 was performed endoscopic repair of the defect. Only one patient had recurrence. Conclusion: The experience in our service demonstrates that the endoscopic approach has earned its place in the treatment of CSF leakage. The results for the corrections are favorable, with good success rate and few complications
