A prospective study was conducted to assess the effect of sealant usage on postoperative cerebrospinal fluid (CSF) leak rate following standard reconstruction.<\/jats:p><jats:p>\n          Methods\u2003A prospective trial of sealant usage after endoscopic endonasal skull base surgery was performed from May 2016 to June 2019 at a tertiary referral cranial base center. This study enrolled 300 consecutive adult and pediatric patients with skull base pathology who underwent EES in which an intraoperative CSF leak occurred. Patients were sequentially stratified into equally sized groups who did or did not receive sealant as part of their reconstruction.<\/jats:p><jats:p>\n          Results\u2003Three hundred consecutive adult and pediatric patients were enrolled in the study and had a confirmed intraoperative CSF leak. The intervention cohort with sealant (first 150 patients) had 21 postoperative CSF leaks (14% rate) compared with 9 postoperative CSF leaks (6% rate) in the control group without sealant (p\u2009=\u20090.02). On multivariate analysis, sealant usage was associated with a higher rate of postoperative CSF leak (odds ratio [OR]\u2009=\u20092.7; p\u2009=\u20090.025). Male gender (OR\u2009=\u20092.4; p\u2009=\u20090.04) and high-flow intraoperative CSF leak (OR\u2009=\u20093.1; p\u2009=\u20090.038) were also found to be associated with postoperative CSF
