Temporomandibular joint changes
TMJ
To analyze the condylar head positional changes within the glenoid fossa; the most middle-superior point of the mandibular condyle was determined in sagittal, axial, and coronal viewsHorizontal line was placed through the widest width of the condylar head (A), three lines crossing the glenoid fossa at 45°(B), 90°(C), and 135° (D).Anterosuperior, superior, posterosuperior, and posterior TMJ spaces.And to assess the lateral changes of the condylar head; the geometric center of the condylar head was determined in the axial slice as the point of intersection between the greatest anteroposterior and mediolateral diameter of the condylar process (Fig. The geometric center of the condylar head as the point of intersection between the greatest anteroposterior and mediolateral diameter of the condylar process.The linear distance between the geometric center to the midsagittal plane was measured (Fig. The lateral distance between the geometric center of the condylar processes to the midsagittal plane.The angel between the condylar long access of the mandibular condyle and the midsagittal plane.
