There were no differences in the HB system between the DG and NDG at the start of treatment and at 1 month after onset. However, facial movement in the DG was poorer than that in the NDG at 3 months and 6 months after onset. In terms of the recovery rate, the rate in the DG (52.6%) was much lower than that in the NDG (82.5%) at 6 months after onset.

Promoting postoperative aeration of the entire middle ear is necessary to achieve better hearing outcome in patients undergoing CWD tympanoplasty and SWR for cholesteatoma.

Our preliminary findings suggest that the pedicled TPFF has positive effects on quick epithelialization. Further prospective studies are needed to reveal the superiority of the pedicled TPFF over free DTF with regard to postoperative infection and recovery of mastoid aeration.
