ABSTRACT

Objectives: To investigate the aided benefits, speech recognition in quiet and in noise, change in hearing and subjective report of satisfaction on mixed hearing loss adults implanted with Vibrant Soundbridge (VSB) middle ear implant.

Methods: Eight Cantonese speaking adult patients with mixed hearing loss were enrolled in a single-subject, repeated measures prospective study design. Audiometric testing, including air and bone conduction and word recognition under sound-field were conducted before surgery. Device activation was arranged 8 weeks after operation. Audiometric testing was taken to evaluate the change in hearing. Patients were asked to wear the device and come back for fine tuning as needed. Outcome measurements were undertaken at 3 and 6 months after device activation. The outcome measures included sound-field thresholds, Cantonese Hearing in Noise Test (CHINT), Abbreviated Profile of Hearing Aid Benefit (APHAB) and International Outcome Inventory for Hearing Aids (IOI-HA).

Results: The application of the VSB improved the aided thresholds and improved speech intelligibility in quiet and noise without significant changes in hearing thresholds.

Conclusion: VSB is considered as a safe, effective and reliable auditory rehabilitation option for Cantonese speaking adults with mixed hearing loss.

Figure 2: Pre and postoperative sound field thresholds for seven mixed hearing loss patients. Triangle, unaided sound field thresholds; circle, aided sound field thresholds evaluated at 3 months after activation of the implant; square, aided sound field thresholds evaluated at 6 months after activation of the implant. SF, speech front.

Mentions: Fig. 2 shows the functional gain at the frequencies 250 Hz to 8 kHz. The functional gain produced by the VSB was determined by differences of the aided thresholds (VSB on) and the unaided thresholds (VSB off) obtained in the sound field with warble tones. The non-implant side was plugged and muffed during testing. The average functional gain at 0.5, 1, and 2 kHz were both about 11 dB evaluated at 3 and 6 months after activation of the implant.
