Computer-assisted designed and computer-assisted manufactured polyetheretherketone prosthesis for complex fronto-orbito-temporal defect.

摘要: w c t Trauma to the cranium and fronto-orbito-temporal region can result in devastating defects. Comminuted frontal-orbital bone fractures may preclude reconstruction with plates screws. Cranial defects also due loss of flap from prior neurosurgical intervention such as evacuation traumatic intracranial hematoma. Fronto-orbital present functional, esthetic, psychologic consequences. Reconstruction these is necessary provide protection underlying brain globe, restoring form symmetry cranial vault. Presently, most commonly used materials include autologous grafts, titanium mesh, methylmethacrylate, polyethylene sheets, hydroxyapatite cements. Each material has its advantages disadvantages, search for an ideal calvarial replacement continues. With advancement computed 3D imaging rapid prototyping, computer-assisted designed manufactured (CAD-CAM) prostheses are gaining popularity. Common CAD-CAM cranioplasty highdensity implants (Medpor; Porex Surgical Inc, Newnan, GA), custom implants, polyetheretherketone (PEEK) implants. The
