Endoscopic Repair of Anterior Skull Base Cerebrospinal Fluid Leaks is Successful in Frail Patients.

Objective: Surgical frailty estimates a patient's ability to withstand the physiologic stress of an intervention. There is limited data regarding the impact of frailty on endoscopic cerebrospinal fluid (CSF) leak repair.

Methods: Patients undergoing CSF leak repair at two tertiary academic skull base programs were retrospectively reviewed.
