Abstract
The electro-cochleogram, as it has been performed in the Audiological Department for more than a year, on adults, on children or on the new-born, has shown different pathological conditions. Already the responses can be classified into different groups according to their pattern, amplitude, latency and to the curves representing their variations with the intensity of the click. In addition to normal response, different types can be differenciated: the recruiting response, the broad response, the abnormal response, etc. Indeed many different patterns can be observed in between these characteristic patterns. But it is believed that each individual response is the precise image of a particular condition in the peripheral receptor. Thus it seems that a more detailed analysis of each pattern, together with the study of a greater number of cases, will allow, later on, a more precise diagnosis.
