Analysis revealed a significant correlation of intraoperative gain in ABR threshold with the postoperative gain in sound field thresholds.ConclusionABR monitoring can be a useful tool to provide information intraoperatively about the coupling efficiency of the FMT. Especially in revision surgeries, this might help to improve postoperative hearing success. 收起
