An unpublished study conducted at Toulouse University Hospital revealed that 30% of implanted children with Autism Spectrum Disorders abandon their implant, while 70% of them keep it. The aim of this study is to evaluate the causes of this disparity, which is much greater than in children with cochlear implants without associated Autism Spectrum Disorders. Our problem is as follows: do the sensory hypersensitivity and hyposensitivity of deaf children with Autism Spectrum Disorders have an effect on the expected results after a cochlear implantation from a language and auditory reaction point of view?

The present study will specifically focus on the sensory profile of these children with Autism Spectrum Disorders, which could be the cause of these developmental difficulties in language and communication development.

Inclusion Criteria:

• Deaf child with cochlear implant
• 15 months to 10 years old and 6 months old at the time of implantation
• Child with autism spectrum disorder (only for children group with autisme spectrum disorder)
• No opposition from the legal representative of the authority to participate in the study

Exclusion Criteria:

• Opposition by the legal representative of the child
• Child under legal protection

Study population is deaf children with cochlear implant. In the first group, children must have cochlear implant and autism spectrum disorders, and in second group, children must have only cochlear implant.
