Dura and cranial base reconstruction by external oblique fascia and rectus abdominis muscle flap

The rectus abdominis muscle flap, combined with the external oblique fascia, were utilized in cranial-base reconstruction. In a wide defect caused by resection of a giant meningioma, the dura was reconstructed with the external oblique fascia and anterior sheath, and the cranial-base defect was reconstructed with the rectus abdominis muscle flap.
