About this study
Official title: Outcome of Cochlear Implant in Children at Assiut University Hospital
Evaluation of the outcome of cochlear implanted children at audiovestibular medicine unit in Assiut university hospital.
Read the detailed description
Hearing loss is one of the most common health problems affecting people around the world with an average international incidence of 5% .
In Egypt, it affects 16% of the population with an incidence of 14% in children less than 14 years old. 86% of deaf patients had conductive hearing loss (CHL), while sensorineural hearing loss (SNHL) was found in 14%, with a male to female ratio of 3:2 HL .
Cochlear implantation (CI) has become a routine procedure in the United States and worldwide for the management of severe-to-profound SNHL loss. It is a remarkable example of success that was made possible through collaboration between engineers, surgeons, scientists and the medical community .
Early cochlear implantation had a long-term positive impact on auditory and verbal development, if auditory stimulation does not occur within this timeframe, the auditory system degenerates. It has been suggested that in the absence of normal auditory stimulation there is a period of about 3.5 years during which the central auditory system retains its maximum plasticity. This can extend in some children up to the age of approximately 7 years, after which it is significantly reduced. The earlier implantation causes better outcomes, including improved language development, speech perception and speech production skills .
Early research reviews found that the ability to communicate in spoken language was better the earlier the implantation was performed. These reviews also found that cochlear implants provide open set speech understanding for the majority of implanted profoundly hearing-impaired children, and that it was not possible to accurately predict the specific outcome of the given implanted child .
Research since then has reported long-term socio-economic benefits for children as well as audiological outcomes including improved sound localization and speech perception .
The outcome of CI surgery on Quality of Life (QoL) has been greatly investigated via parental questionnaire assessment. This questionnaire was designed with 11 subscales and 58 questions in total. All questions were scaled from 1 to 5: (1 strongly agree; 2 agree; 3 neither agree nor disagree; 4 disagree; and 5 strongly disagree) .

Questions about this trial
What is this clinical trial studying?
An observational study of Cochlear Implant, run by Assiut University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 22 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sally Shenouda Bolis, Master (+201552431299, sallyshenouda1993@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Parents' perspective Questionnaire (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05275712, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2023.
