Background: Children born with severe or profound hearing loss usually have delays in receptive and expressive language development that affect academic achievement and social functioning. Cochlear implantation is the treatment of choice for these children. There were very few studies on developmental outcome of the children with severe sensory neural hearing loss who had gone through cochlear implantation.

Objective: 1) To assess developmental outcome of cochlear implantation in children aged 9 to 66 months. 2) To study attitude and Parenting Styles and Dimensions Questionnaire (PSDQ) of the parents.

Materials and Methods: A cross-sectional descriptive study of 27 children aged 9 to 66 months who received cochlear implantation at Rajavithi Hospital. The data were collected online using the Ages & Stages Questionnaires, Third Edition, Thai-Version (ASQ-3 Thai), Parents’ attitudes and PSDQ, Thai version.

Results: The age of cochlear implant was 30.52±12.22 months with 29.6% of the patients getting the cochlear implantation before two years of age. There was 70%, and 37% of children suspected of having delays in language and problem solving. Relationship between language development with age at diagnosis of hearing impairment, age of receive hearing aids, age of auditory-verbal therapy, age of cochlear implantation, and duration of auditory verbal training after cochlear implantation were statistically significant. There was a significant relationship between problem solving and reading with children family type. Most parenting style was authoritative. Parental knowledge and attitudes were very good at 96.3%.

Conclusion: Children with severe sensory neural hearing loss who received early diagnosis and cochlear implantation at the age younger than 2 years old, as well as long consecutive auditory and speech skills training, results in better language developmental outcomes.
