case_images: 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.

case_images: 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).
case_images: (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).

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

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

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