Postoperative imaging. A, B and C Computed tomography (17-year follow-up). The presence of poly(methyl methacrylate) (PMMA) components used in the Puricelli biconvex arthroplasty technique is observed on the right side. The components are stabilised in the initial position, near the base of the skull and the condylar region of the mandible. D Computed tomography with 3D reconstruction (39-year follow-up). Stability of the prosthetic components is observed, with no surgical reintervention during this period. E and F Frontal and lateral radiography, respectively (39-year follow-up). The facial skeletal relationship shows normal patterns
