title: Successful endoscopic repair of persistent cerebrospinal fluid leak following attempted transcranial repair.
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.
