"90% of children with a CI will be successfully included in mainstream education provided they do not have an additional handicap and they get adequate rehabilitation with family support".

Step 1: Is there a hearing loss?

Factors

Key Factors supporting the dramatic changes in indication-          Continuous advances in technology (diagnostic equipment, hearing aids, implants, FM, assistive listening devices)-          Improved imaging and surgical techniques-          User friendly software for fitting and trouble shooting of cochlear implants-          Proven rehabilitation methodologies (e.g. oral education, auditory verbal approach)  

Indication

Broadening of indication

-          Age (6 months - > 80 years)

-          Severity of hearing loss  (“totally deaf” – “severely hearing impaired” – “partially deaf”)

-          Bilateral deafness – unilateral deafness

-          Unilateral CI – bilateral CI – bimodal (HA + CI)

-          Children whose mother tongue is not the language of the country they are living in

-          Multiple handicapped children / autistic children

-          Deaf children with deaf parents

"90% of children with a CI will be successfully included in mainstream education provided they do not have an additional handicap and they get adequate rehabilitation with family support".
