Hydroxyapatite cranioplasty in fibrous dysplasia of the skull.

We describe the case of a woman who had complained of worsening headache during the previous year. Analysis of computed tomography imaging and biopsy led to a diagnosis of fibrous dysplasia of the skull. A symptomatic frontal bone lesion was removed, and the resulting defect was repaired with hydroxyapatite cement. Hydroxyapatite cement has several advantages over hydroxyapatite ceramic blocks and granules, and it is particularly well suited for calvarial reconstruction.
