Iatrogenic atlantoaxial rotatory subluxation after thyroidectomy in a pediatric patient: A case report

Figure 1 Preoperative imaging. A: Computed tomography of the neck before thyroidectomy showing no subluxation of C1–2; B: Computed tomography coronal view after thyroidectomy showing the asymmetry of the lateral atlantodental interval; C: Plain radiograph showing the “cock robin” position of the head; D: Open mouth view showing the asymmetrical atlantodental interval and narrowing atlantoaxial joints (yellow arrow); E: Computed tomography showing the anterior subluxation of C1 on C2 at the left facet joint and the posterior subluxation of C1 on C2 at the right facet joint.

Figure 2 Postoperative cervical dynamic radiographs of a stable atlantoaxial joint. A: Open mouth radiograph showing the reduction of the “cock robin” position of the head; B and C: Lateral flexion dynamic radiograph showing C1–2 fusion and no instability.
