Abstract
BACKGROUND: Repair of the anterior skull base for cerebrospinal fluid leak requires either endoscopic endonasal approach or open transcranial approach.
OBJECTIVE: To present a less invasive surgical procedure for sealing of the entire anterior fossa floor for traumatic rhinoliquorrhea.
METHODS: Cadaver study in 3 head specimens. Endoscopic placement of a furled bovine pericardial patch bilaterally along the sphenoid ridge and planum in guidewire technique. Unfurling and spreading of the patch under endoscope assistance.
RESULTS: Patch placement was feasible in all 3 specimens without visible injuries to the frontal lobes. Dissection and preservation of the olfactory tracts was only possible for 50% of olfactory tracts.
CONCLUSION: Endoscopic transcranial keyhole duraplasty is a promising concept for traumatic rhinoliquorrhea.
