Computed tomography (CT) findings after cell sheet transplantation in all the cases. All temporal bone CT findings are observed in a coronal view, and for each case, the left panel indicates the view before, whereas the right panel indicates the view after cell sheet transplantation. In all the cases, preoperative CT showed that the tympanic membrane was adherent and the aeration in the tympanic cavity was lost. In five out of six cases, aeration was observed in the tympanic cavity (the area circled in red) after cell sheet transplantation.
