Objective:
To investigate the benefit of intraoperative auditory brainstem response (ABR) measurements in revision active middle ear implant surgery.
Study Design:
Retrospective data analysis.
Setting:
Tertiary referral center with a large active middle ear implant program.
Main Outcome Measures:
Intraoperative ABR thresholds, audiogram, sound field thresholds, speech understanding in the Freiburger monosyllabic word test.
Patients:
Fourteen patients with active middle ear implant revision surgery.
Results:
The application of the ABR measurement resulted in improved sound field thresholds and enhanced speech understanding. Analysis revealed a significant correlation of intraoperative gain in ABR threshold with the postoperative gain in sound field thresholds.
Conclusion:
ABR 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.
