Dural substitute
Absorbable, porous collagen or synthetic sheet matrix, applied on-lay or sutured over a dural defect, gradually replaced by the patient's own regenerated dural tissue.
How it is used
Duraplasty or dural closure after craniotomy or spine surgery when primary closure is not possible or not watertight.
Clinical tip
FDA-reviewed data (1,096 patients) described full replacement of the collagen matrix by the patient's own tissue within 8-12 months, with infection rates comparable to other graft types.
