Optimal reconstruction of the bony defect after frontotemporal craniotomy with hydroxyapatite cement.

Numerous procedures have been reported for reconstruction of the bony defect around the sphenoid ridge after a frontotemporal craniotomy. However, it is still often difficult to restore the defect because of the complex curvature. Here we describe a simple cranial reconstruction method using hydroxyapatite cement and gelatin sponges. This procedure has been used on six patients, and satisfactory reconstruction was confirmed in all with postoperative three-dimensional CT scans. Using this technique, the bony defect was completely reconstructed with an appropriate thickness and curvature.
