Outcomes

Primary Outcome Measures

Change in Speech Reception Threshold (SRT)
Comparison of the speech reception threshold (SRT) using the Esteem System as compared to the pre-implant aided condition. The SRT is related to hearing sensitivity; lower numbers indicate better outcomes. Here, the difference in dB is reported; positive scores indicate improvement (lower SRT) with the Esteem relative to the pre-implant hearing aid. There are no specific minimum or maximum scores for this measure.
Change in Word Recognition Score (WRS)
Comparison of the word recognition score using the Esteem compared to the pre-implant aided condition. For WRS, a higher score indicates a better outcome. Here, the difference in % correct is reported; positive scores indicate better performance with the Esteem relative to the pre-implant hearing aid. Scores on this test range from 0 to 100%.
Incidence of SADEs, Device Failures, & Replacements
The analysis of the incidence of Serious Adverse Device Effects (SADEs) and device failures and replacements
Incidence of Facial Pareses/Paralysis
The analysis of the incidence of facial pareses/paralysis at one month follow-up
Change in Bone Conduction Threshold (BCT) at 500 Hz
Comparison of bone conduction (BC) threshold at 500 Hz post activation compared to the pre-implant BC threshold. Change in Bone Conduction is used to determine whether residual cochlear function has declined following implant of the Esteem. Positive numbers indicate higher (i.e., poorer) bone conduction thresholds post-implant, relative to pre-implant.
Change in Bone Conduction Threshold (BCT) at 1000 Hz
Change in BCT from Baseline to 10-month post-activation. Change in Bone Conduction is used to determine whether residual cochlear function has declined following implant of the Esteem. Positive numbers indicate higher (i.e., poorer) bone conduction thresholds post-implant, relative to pre-implant.
Change in Bone Conduction Threshold (BCT) at 2000 Hz
Change in BCT from Baseline to 10-month post-activation. Change in Bone Conduction is used to determine whether residual cochlear function has declined following implant of the Esteem. Positive numbers indicate higher (i.e., poorer) bone conduction thresholds post-implant, relative to pre-implant.
Change in Bone Conduction Threshold (BCT) at 4000 Hz
Change in BCT from Baseline to 10-month post-activation. Change in Bone Conduction is used to determine whether residual cochlear function has declined following implant of the Esteem. Positive numbers indicate higher (i.e., poorer) bone conduction thresholds post-implant, relative to pre-implant.

Secondary Outcome Measures

Change in Subjective Quality of Life as Measured With the Abbreviated Profile of Hearing Aid Benefit, or APHAB (Global Score)
Quality of Life measured with the APHAB comparison between the pre-implant aided condition and 10-month post-activation. In general, a lower score indicates better performance. The range of scores for each subscale (including the Global score, reported here) is 1 to 99. Here, mean difference in benefit score with the Esteem implant vs. pre-implant aided condition is reported. A positive difference score indicates more benefit with the Esteem.
Esteem Questionnaire Results
To gather subject feedback and comments on the use of the Esteem System through subject ratings on questionnaire items specifically focusing on factors such as the clarity of sound, the user's ability to understand speech in background noise, naturalness of sound, benefits of the system, etc. -- relative to the pre-implant aided condition. Subjects rated each item as "Is much worse", "Somewhat worse", "Is about the same", "Is somewhat better", or "Is much better" with the Esteem. Reported here are the cumulative number of respondents indicating "Same", "Somewhat better", or "Much better" for the given question.

5. Study Description

Brief Summary
The New Enrollment Post-Approval Study is designed to evaluate the safety and efficacy of the Esteem Totally Implantable Hearing System in subjects suffering from moderate to severe hearing loss.
Detailed Description
Purpose: To evaluate the long-term safety and efficacy of the Esteem Totally Implantable Hearing System (hereafter called Esteem) in subjects suffering from moderate to severe hearing loss. Questions: The following questions are to be answered: Is Esteem effective through 1 year follow-up? Is Esteem safe through 1 year follow-up? Is the incidence of facial paresis/paralysis at 1 month follow-up no greater than 7%?
