Photographs show an anomalous head posture of right-turning facial position, an abduction defect (-4), and an esodeviation of 30 prism diopters in his right eye. Informed consent was received from parents of the patient.

On the first day after surgery, an esotropia of 30 prism diopters (PD) and an abduction limitation (-4) occurred in his right eye, and facial turn to the right appeared (Fig. 1).
(A) Preoperative axial enhanced T2-weighted magnetic resonance (MR) image shows right otomastoiditis. (B) Preoperative coronal enhanced T2-weighted MR image shows right otomastoiditis. (C) Axial enhanced T1-weighted MR image shows slow flow velocity of the right transverse sinus (white arrow). (D) Coronal enhanced T1-weighted MR image shows slow-flow velocity of the right internal jugular vein (black arrow).

The thrombus, however, was not significant (Fig. 2).
Computed tomography of the right temporal bone shows no inflammation of the petrous bone (white arrow) and an erosive mastoid septa (black arrow).

Temporal bone computed tomography showed erosive changes in the right mastoid adjacent to the sigmoid sinus, but petrous apicitis was not observed (Fig. 3).
Photographs show orthotropia and no limitation of abduction in the right eye at 4 months after mastoidectomy.

Four months after surgery, he had fully recovered from the esotropia, limitation of ocular movement, and anomalous head posture (Fig. 4).
