Figure 3

(a) A 3D volume rendering scan shows the amount of bone removed during lateral petrosectomy. The drain was inserted into the abscess cavity through the defect in the anterior EAC wall (arrow). (b) Intraoperative image: a defect in the anterior wall of the tympanic cavity (arrow). Pus under the pressure appeared when the granulations were removed from the tympanic cavity. (c) After the tympanic part of the temporal bone was partially drilled, a large bony sequestrum was removed with microforceps. (d) Finally, the third type of tympanoplasty was carried out.
