Extensive and complex defects after neurosurgical oncologic resections including dura are a challenge, as watertight closure is of paramount importance.

The vascularized peritoneum appears to be an excellent biological replacement for the dura and the well-vascularized muscle promotes wound healing and obliterates dead space.
