Outcome Measures

Primary Outcomes (1)

  • Correlation of eABR results to postoperative hearing results

    eABR is correlated with postoperative hearing results eABR will be divided in three categories - good response, weak response, no response. Hearing results will be measured with speech understanding in Freiburg monosyllables word test which is measured in % of monosyllables understanding at 65 and 80dB
