Repair of Occipital Bone Defects in Neurofibromatosis Type 1 by Means of CAD/CAM Prefabricated Titanium Plates

[摘要] Certain skeletal defects may develop in neurofibromatosis type 1 (NF1), a common tumor-suppressor syndrome, such as cranial lesions confined to the lambdoid suture region. Here, we report on the repair of osseous defects of occipital bone in a NF1 patient with history of skull trauma and tumorous hemorrhage. Computer-aided design and computer-aided manufacturing (CAD/CAM)-assisted devices were applied to safely close the bone defects. The variable phenotype of NF1 in the occipital skull region is discussed and a brief review is presented on NF1-related therapies for tumors and malformations of the occipitoparietal skull region.
