Abstract
Endoscopic techniques have become the preferred approach to address cerebrospinal
fluid (CSF) leaks in the skull base, as they offer a minimally invasive method to
directly visualize and repair the defect. The alternative technique of open craniotomy
can still be considered for cases refractory to endoscopic repair; however, few studies
have investigated the potential benefits of endoscopic repair for cases of persistent
leaks after attempted transcranial repair. We report two such cases of successful
long-term endoscopic repair of a persistent CSF leak, and demonstrate that endoscopic
repair is a viable option to salvage an unsuccessful intracranial repair.
