Axial (a) and coronal (b) view of 3DCT before treatment. The atlas was rotated without dislocation of the odontoid process in axial view. The axis showed slight oblique position against atlas in coronal view.

Three-dimensional CT (3DCT) revealed asymmetry in atlantoaxial joint and rotation of the atlas with the odontoid process acting as pivot (Figure 1).
Axial (a) and coronal (b) view of 3DCT after treatment revealed normal appearance in atlantoaxial joint.
