After trauma a part of the skull might be damaged or lost. A reconstruction of the skull can be performed using patient specific implants. The implants are designed to exactly fit the defect and restore the patient anatomy. Reconstruction includes the skull bone, but can also incorporate surrounding structures such as the orbital roof, orbital wall, orbital rim or zygoma. The patient specific 3D virtually designed implants enables us to perform reconstructions that may have not been possible using conventional reconstruction methods.
