Preventing cerebral spinal fluid leakage following endoscopy through a burr hole using a novel watertight closure: technical note

Abstract

Background Cerebrospinal fluid (CSF) leakage is a common complication after neuroendoscopic surgery through a burr hole and can lead to further complications including infection. Methods We describe the use of a dural substitute larger than the burr hole itself, placed over the burr hole and then secured underneath a burr hole cover by microscrews running through the graft itself into the underlying skull. Results This simple technical modification contributes to achieving a watertight seal to aid in preventing CSF leakage in this setting. Conclusions Our technical modification of endoscopy through a burr hole may help to prevent postoperative CSF leak and secondary CSF infections.
