[On infantile audiometry: the Bordeaux strategy].

Infantile "subjective" or behavioural audiometry requires highly skilled pediatric audiologists. It is indeed often said in the majority of centres that any subjective examination is impossible under the age of 3, whereas in our clinic we successfully complete extremely precise tests, including in bone conduction, as from the age of 6 months. The strategy and techniques employed to obtain audiometric curves with headphones as from such an age are described. Subsequently, the statistical studies covering over 600 cases are presented, evidencing the earliness, accuracy and reliability of the curves obtained over nearly 15 years in Bordeaux by the method described.

[Role of electrophysiology in the current diagnosis of deaf children].

The role of electrophysiology (auditory evoked potentials) in children up to 3 years old was studied through the feasibility and results of subjective audiometry. In children over six months old, subjective tests are performed systematically or at least tried before using electrophysiology. Electrophysiology is required when audiometry is impossible, and it is often performed when audiometry is abnormal. When subjective tests were not performed first, either because the child is too young or shows a developmental retardation, and the electrophysiological tests are abnormal, it is absolutely necessary to obtain an exact level of hearing as soon as possible using subjective tests. The results of a study on 244 electrophysiologically tested children between the 0 and 3 years of age are presented briefly. In 73% of the cases, the auditory brainstem responses were sufficient for clarifying or confirming the subjective tests. In 27%, they had to be completed be an electrocochleography (ECochG) under general anesthesia. The information based on the ECochG and the comparison data between the ECochG and subjective thresholds are presented. On one hand, this study highlights the double complementarity between audiometry and electrophysiology on the other, the brainstem potentials and ECochG.

[Early audiometry].

Data obtained from electrophysiology are insufficient both for the audioprosthetist and for the speech therapist. In order to meet the requirements for the increasingly early equipping and training of deaf children, we have developed in the Bordeaux Audiology Laboratory an audiometric strategy making it possible to obtain, as early as 5 to 6 months old, bone curves on the vibrator, and air curves on the head-set. In addition to the auditive information that can be obtained, the test described forms, by its design, the starting point of early training and parental guidance. Its success is based on the relationship that is established between the child and the investigator. Early audiometry is possible. It is essential prior to any therapeutic approach.
