Yu JK, Tsang WS, Wong TK, Tong MC - Clin Exp Otorhinolaryngol (2012)

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

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.

CHINT results in noise for the seven mixed hearing loss adults evaluated at unaided, Vibrant Soundbridge (VSB) on at 3 months and 6 months intervals after activation of the implant. The smaller the speech reception thresholds (SRT) represented the better speech recognition performance. *The change in SRT in noise between unaided and aided 3 months and aided 6 months condition was statistically significant (P<0.05).

Figure 3: CHINT results in noise for the seven mixed hearing loss adults evaluated at unaided, Vibrant Soundbridge (VSB) on at 3 months and 6 months intervals after activation of the implant. The smaller the speech reception thresholds (SRT) represented the better speech recognition performance. *The change in SRT in noise between unaided and aided 3 months and aided 6 months condition was statistically significant (P<0.05).

Mentions: Fig. 3 summarizes data concerning SRT in noise, presented on the implant side and non-implant side, as signal-to-noise ratios (SNRs). The speech recognition in noise using the VSB was significantly better in comparison to the unaided conditions at noise front and noise at non-implant side conditions in comparison to unaided mode (Wilcoxon signed rank test, P=0.028 at 3 months and P=0.027 at 6 months). All subjects demonstrated an increase in speech understanding with the VSB, the SNR improvement of maximum 2.8 dB at noise front, 1.6 dB at noise ipsilateral and 7.1 dB at noise contralateral conditions evaluated 6 months after device activation.
