The purpose of this article is to review the endoscopic management of cerebrospinal fluid (CSF) leaks and encephaloceles, with particular emphasis on safety and efficacy, by retrospective assessment utilizing the results of a mailed questionnaire. Surveys were mailed to members of the American Rhinologic Society with practices in both academic centers and/or private settings. Survey results were then assessed and tabulated. There were 635 mailings, with 197 responses (31%). Seventy-two (36% of respondents) indicated that they performed endoscopic management of CSF leaks and encephaloceles, while 125 (64% of respondents) did not. Respondents reported similar to 522 cases of CSF leaks and similar to 128 cases of encephaloceles managed by endoscopy. Success rates after a single procedure were estimated at 90% for CSF leaks and 93% for encephaloceles. Success rates after a secondary procedure were estimated at 86% and 97%, respectively; 29% of respondents have, at some point, made a referral to neurosurgery. A total of 13 complications related to endoscopic repairs were reported (2.5%). For CSF leak repair complications included seizures, 0.2%; meningitis, 1.1%; and one reported case each of cavernous sinus thrombosis, temporary visual problems, sinusitis, and intracranial hypertension/bleed. There was only one reported death in the similar to 522 cases. Eleven complications following encephalocele repairs (8.5%) included seizures, 3.1%; meningitis, 2.3%; and one reported case each of brain abscess, sinusitis, false aneurysm of middle cerebral artery, and mild dizziness. No deaths following encephalocele repair were reported The endoscopic management of CSF leaks and encephaloceles has become increasingly popular and has proven to have low morbidity and mortality with high success. Overall, our results confirm that in the hands of the skilled endoscopist, endoscopic management of CSF leaks and encephaloceles is highly efficacious and has a very low incidence of significant complication.
