title: Norian craniofacial repair system bone cement for the repair of craniofacial skeletal defects.
abstract: OBJECTIVE
  To describe the use of the Norian Craniofacial Repair System (CRS) calcium phosphate bone cement in the restoration of craniofacial skeletal defects.
  
  
  METHODS
  Consecutive case series.
  
  
  RESULTS
  Calcium phosphate bone cement was used to repair craniofacial skeletal defects in three patients. Indications included repair of a posttraumatic orbital floor defect causing hypo-ophthalmos, reconstruction of frontal craniotomy and temporalis muscle donor sites in a patient who had undergone resection of an invasive squamous cell carcinoma, and augmentation of a post-traumatic anterior maxillary skeletal defect. The primary outcome measure was the restoration of bony volume and support. The use of calcium phosphate bone cement in these patients was effective and without complications.
  
  
  CONCLUSIONS
  Norian CRS calcium phosphate bone cement is useful in the repair of craniofacial skeletal defects.
