"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".
