- Primary Outcome Measures
Name Time Method <p>The main study parameters are ECoG recordings, and specifically their<br /><br>amplitudes that will be compared before, during and after surgery. These<br /><br>measures can be correlated to the standard subjective clinical measures (pure<br /><br>tone audiograms) after surgery.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Benchmark recordings of the ECoG during surgery using standard (high-quality)<br /><br>BERA equipment. Similarly, eCAP recordings will be benchmarked against the<br /><br>normal standard-of care eCAP recordings obtained via the implant electronics.<br /><br>eCAPs will be analyzed through standard methods, including amplitude-growth<br /><br>functions and threshold measurements.</p><br>
