title: [Reconstruction of calvarial donor site using a biomaterial].
abstract: BACKGROUND
  Calvarial bone graft is widely used in cranio-maxillo-facial surgery. But the main sequel is an unsightly depression of the donor site. Reconstruction of the donor site using biomaterial could decrease this depression. The aim of this retrospective study was to evaluate the tolerance of biomaterials and the esthetic result of reconstruction.
  
  
  METHODS
  During a 24-month period, 18 patients were reconstructed with Hydroset™ cement after calvarial bone harvesting. They were followed up for 24 months. The clinical tolerance and esthetic result were assessed, using a questionnaire.
  
  
  RESULTS
  There were neither complications nor residual pain. One patient complained of esthetic impairment. A feeling of depression on touch persisted in 44% of patients. Ninety-eight percent of patients would accept another calvarial graft if needed.
  
  
  CONCLUSIONS
  Hydroset™ is well tolerated. It improves local esthetics by filling cranial bone defects after calvarial bone harvesting.
