[CT-scan evaluation of calvarial bone donor site reconstruction using calcium phosphate cement].
The aim of reconstructing a calvarial donor site with biomaterial is to reconstruct the skull vault. The aim of this retrospective study was to assess the quality of reconstruction of calvarial bone with Hydroset™ (Stryker™) in patients having undergone monocortical parietal bone graft harvesting.


METHODS
The donor sites of patients having undergone calvarial bone harvesting had been reconstructed with Hydroset™ cement over a period of four years. Calvarial bone reconstruction and the thickness of the parietal bone were evaluated by CT scan.


RESULTS
Twenty-six patients had undergone reconstruction. The CT scan revealed a good integration of Hydroset™ with maintained thickness of the biomaterial. The parietal bone thickness was increased by 0.67 mm on average (P=0.002).


CONCLUSIONS
The reconstruction of calvarial donor site bone defect with Hydroset™, after a monocortical harvesting, demonstrates parietal osseous thickness maintained in time.
