Spiral computed tomography (CT) analysis of the temporomandibular joint (TMJ) complexes at 12 weeks after surgery. a Three-dimensional reconstruction of a spiral CT image shows more newly formed bone in the control group (white arrow) than in the experimental group. b A horizontal CT section shows that the maximum mediolateral and anteroposterior condylar diameters are larger in the control group than in the experimental group. c and d Coronal and sagittal CT sections show irregular upper and lower articular surfaces, calcified bone callus formation in the joint space (black arrow), a narrowed joint space, and roughened articular surfaces after new bone formation, which protrudes into the joint space in the control group (black arrow). The experimental group shows irregular erosion on the upper and lower articular surfaces (yellow arrow), and the joint space is clear with no intra-articular calcification
