Title: Sealing holes in bony cranial anatomy using custom fabricated inserts

Abstract: An apparatus and method to implant a seal in a skull base defect. The seal is implanted using apparatus with deployable elements which pass up the nasal cavity into the area of the sphenoid sinus where they deploy and expand into useful conformations. A disk is inserted through the skull base defect into an interior side of the skull at the base defect, with a stalk extending through the skull base defect. The stalk is held outward from the skull base defect, holding the disk against the interior side of the skull while a conical mold is filled with bone cement. Once the cement has cured, the apparatus is removed, leaving the insert in the skull with the stalk surrounded by a cone of bone cement, creating a water tight seal in said skull base defect.
