Primary Outcome Measures

Name	Time	Method
Correlation between insertion depth of the cochlear implant electrode and deviation of the actually achieved from the predicted monosyllibic speech recognition score at 65dB (Freiburger Sprachverständlichkeit nach DNI 45621).

Secondary Outcome Measures

Name	Time	Method
