PROSTHETIC FITTING OF THE HEARING-IMPAIRED CHILD
The infant’s hearing channels and centres only mature in response to
an early, well-adapted and regular stimulation by sound.
BIAP consequently recommends :
1. that the deafness diagnosis be established as early as possible. It can often be made during the first months. Prosthetic fitting must be carried out promptly (cf. annex).
2. that this fitting result from multidisciplinary care involving ENT doctors, audiologists, hearing-aid specialists, speech therapists, pedagogues and psychologists (cf. BIAP recommendations CT 14 ; audio-phonological team, definition).
All these participants must have acquired the training and experience necessary for
specialism in this field.
1.- Prosthetic fitting of children is strictly dependent on
the diagnosis
In the case of suspected deafness, the audiological assessment must
be as complete as possible. It requires the use of tests adapted
to the child’s age and aptitudes. It is essential to look for the
presence of any disability related to deafness, necessitating a paediatric
or neuro-paediatric examination or any other examination needed for diagnosis.
2.- Prosthetic fitting of children requires the parents’ decision and collaboration.
Parents should be given exact information about hearing-aids, the need
for fitting and the benefit for the child as well as the drawbacks of wearing
the device
(cf. BIAP recommendations CT-25-1
: parental guidance).
3.- Prosthetic adaptation
Prosthetic adaptation should normally be bi-aural and stereophonic,
unless there are clinical counter-indications. It should be carried
out immediately after the first diagnosis and continue to evolve according
to the child’s age and perception capacities.
4.- Speech therapy care
It shall be practised as soon as possible after the diagnosis and, like
the hearing-aid, continue to adapt to the child’s development.
This pluri-disciplinary care shall be given in close and continuing
collaboration with the family
(cf. BIAP recommendations CT-25-01
: parental guidance Annex 1-C).
5.- Evaluating efficacy of the hearing-aid
5.1 Efficacy shall be assessed by paedo-audiometry examinations adapted to the
child’s age and aptitudes to determine the residual hearing dynamics available
for understanding speech.
5.2 As far as possible, it shall be evaluated by vocal audiometry tests.5.3 Finally, the child’s development, observation of his/her behaviour, vocal
productions, reactions to noise and to a wide variety of stimulation,
comprehension capacity, aptitude for communication, shall be important
elements for evaluation. This requires constant, careful observation that can be
done by parents with the help of the audio-phonological team.
(cf. BIAP recommendations CT-25-1 : parental guidance Annex 1-D).
6.- Follow-up (or continuous assessment)
Follow-up for children means constantly adapting the hearing-aid to
the child’s development, audiometric evaluation becoming more and more
precise.
The acceptance of hearing-aids, their setting and efficacy must be
constantly checked as must be the auricular tips which, in children,
have to be regularly renewed.
Audiometric verification and checking of the electro-acoustic characteristics
of the hearing-devices should be carried out as frequently as is necessary
in view of the development of the hearing impairment and the child’s aptitudes
as well as the parents’ and the multidisciplinary team’s demands.
Particular attention should be paid to the excessive risks of output acoustic
pressure.
The child’s hearing, language and intellectual development must come
under constant observation by the pluri-disciplinary team and especially
the parents.
ENT medical follow-up is also necessary at least once a year particularly
in the case of rhino-pharingitis and sero-mucous otitis which affect the
efficacy of the device. For any hearing degradation, medical advice
should be sought without delay.
7.- Related disabilities
The child with disabilities may present hearing impairment. Given
the potentially negative effect of a hearing impairment on communication
development, it is essential to test the hearing of all children with disabilities.
If hearing impairment is detected, the fitting of a hearing-aid, followed
by suitable rehabilitation, must take place as soon as possible (cf. BIAP
recommendations CT-21-03 : Multiple disabilities and hearing damage,
deafness and related disabilities).
8.- Cochlear implants
During the follow-up of the hearing-impaired child, a cochlear implant
may be proposed if the efficacy of the hearing aid and the benefit to the
child are insufficient (cf. BIAP recommendations
CT-07-1 : Cochlear implants).
