This project will complete a long-term follow up for children that have received cochlear implants (CI) early in life and had their CI's programmed based on objective measurements. At Sahlgrenska University Hospital in Gothenburg, generally, all younger children (0-3 years), the last ten years, had their CI's programmed based on objective measurements. The programming of the CI carried out during the first year after the surgical insertion is done on the foundation of the objective measurements and is generally what the child will live with thereafter. This method also seem to be close to other clinics in Sweden and the rest of the world, however, there are no specific guidelines regarding the how the programming of the CI is to be carried out on small children. To this date there are no studies, to our knowledge, that have confirmed the validity of using these objective measurements and if it is the best for the child. We therefore aim to do a long term follow up on children that have received CI and programmed this way, and study if there would be beneficial to redo the programming when the child is old enough to actively participate. The aim with this project is evaluate how suitable it is to mainly use objective measurements when programming the cochlear implant and, in addition to this, examine if the children's hearing can be improved if the programming is based on the behavioral measurements of sound when the children are old enough to participate in such. It will examine what happens with the end result if the programming foundation differentiates from one another; if there are any measurable differences in hearing skills. The result from this project expects to generate knowledge that is highly important for those working with small children receiving CI's, and by extension it will benefit the children that rely on this device in there every day life.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in speech perception | Sound field hearing test performed with a pre-recorded speech material consisting of everyday sentences. | Performed at baseline and 4 months after intervention | |
Primary | Change in tone threshold | Sound field hearing test performed with tones to determine hearing thresholds. | Performed at baseline and 4 months after intervention | |
Primary | Behavioral T-thresholds | Behavioral measurements of the T-levels that constitutes the the lower level of the dynamic range when programming the cochlear implant (setting the MAP). | Performed at intervention | |
Primary | Behavioral C-thresholds | Behavioral measurements of the C-levels that constitutes the upper level of the dynamic range when programming the cochlear implant (setting the MAP). | Performed at intervention | |
Primary | Change in automatically recorded electrical evoked action potential thresholds | The measurement used for programming the cochlear implant if not behavioral measurements are feasible (e.g. small children). | Performed at baseline and 4 months after intervention | |
Secondary | Change in results from "Children's Home Inventory for Listening Difficulties" questionnaire | The questionnaire "Children's Home Inventory for Listening Difficulties" assesses the subjective effect on the child's hearing of the re-programming of the cochlear implant. The questionnaire refers both the participant (the child) and the caregiver separately, and consists of 15 questions of different everyday hearing situation. Each question is answered on a rating scale of 1 - 8; a higher grading indicates better hearing (i.e. better outcome). The result is presented as a mean of all the ratings for the participant and the caregiver, respectively. | Performed at baseline and 4 months after intervention |
