OBJECTIVES: To evaluate feasibility, surgical handling, audiological outcome, and coupling efficiency of a new coupler (custom-made device) for an active middle ear implant.
PATIENT: Revision surgery after implantation of an active middle ear implant in a 66-year-old male patient with mixed hearing loss.
INTERVENTION: Prosthetic hearing rehabilitation with a new coupler for round window application.
MAIN OUTCOME AND RESULTS: The patient obtained good speech perception in quiet (word recognition scores 80%; Freiburg monosyllables) and noise (-3.3 dB SNR; Oldenburg Sentence Test). The effective gain with the Hannover coupler improved at frequencies > 0.5 kHz compared with the values reported for other round window (RW)-coupling modalities.
CONCLUSION: The coupler provides a feasible option for the RW application of the middle ear implant actuator. The spring concept of the coupler needs to be improved to further standardize RW-coupling and improve coupling efficiency at low frequencies (0.5 kHz).
