title: [Endonasal endoscopic surgery in the treatment of spontaneous or post-traumatic cerebrospinal fluid (csf) leaks].
abstract: The incidence and the risk of meningitidis justify treatment in all cases of cerebrospinal fluid rhinorrhea with spontaneous etiology or after traumatic injury. Endonasal surgery with endoscopic instruments provides many advantages compared with transcranial or transfacial approach used by neurosurgeons. We report our experience and our surgical technique in the treatment of CSF leaks in 5 patients. Intrathecal injection of fluoresceine was very useful in all cases for detecting the CSF leak. Total or selected ethmoidectomy depended on the localization of the leakage. Wide sphenoidotomy enables detection and repair of CSF leaks from the sphenoid cavity. A free graft of inferior turbinal mucosal was used to repair the breache. This rapid low morbidity surgery offered secure closure of rhinorrhea in 4 cases after one procedure and in 1 case after two procedures with an average follow up of 22 months. Cerebrospinal fluid rhinorrhea can be managed in first line therapy with endoscopic intranasal surgical techniques when they are localized in the anterior ethmoid or in the sphenoid cavity.
