A Novel Method of Frontal Bone Reconstruction Using Patient-Specific Implants and Costochondral Grafts: A Case Report.

The frontal bone is the vital component of the human skull and forms a part of the anterior skull vault, base, and roof of the orbits. Frontal bone defects may arise secondary to various causes like trauma, congenital defects including craniofacial clefts, tumors in the frontal bone requiring surgical intervention, and infections, like osteomyelitis, that cause osteonecrosis of the frontal bone. Reconstruction of frontal bone has been explored in the literature, and various materials are available for rehabilitation, like auto/allografts, and alloplastic materials, including bone cement, titanium meshes, and patient-specific implant (PSI). All the available materials have their own advantages and disadvantages; hence, depending on the anatomy and physiology of the frontal bone and the involvement of the naso-orbito-ethmoidal (NOE) complex, patient selection and treatment plan become very crucial. This report presents a case of the frontal bone with a NOE defect, secondary to trauma, reconstructed using a PSI and costochondral graft.
