Abstract
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.
