Summary
Publication rates for cochlear implant (CI) trials remain low, with only 26.5% published. Recent trends show a shift towards rehabilitation and surgical techniques, indicating evolving research in CI development.
Area of Science:
- Otolaryngology
- Medical Device Research
- Clinical Trial Analysis
Background:
- Cochlear implant (CI) research is crucial for hearing restoration.
- Understanding publication efficiency is key to assessing research impact.
- Recent updates may influence research focus and dissemination.
Purpose of the Study:
- To assess the publication efficiency of registered CI trials.
- To characterize evolving research trends in CI following a 2022 update.
Main Methods:
- ClinicalTrials.gov was queried for CI trials completed before October 2022.
- Publication status was verified using PubMed and Google Scholar.
- Trial characteristics were analyzed to identify publication predictors.
Main Results:
- Only 26.5% of 98 completed CI trials were published.
- Publication rates were lowest for industry-sponsored (20.6%) and device trials (20.9%).
- Post-2022 registrations show decreased device trials (43.9% to 31.9%) and increased focus on rehabilitation (13.3% to 20.3%) and procedural refinements (11.2% to 17.4%).
Conclusions:
- A significant gap exists in CI evidence dissemination, with low publication rates.
- While device studies are prominent, research is diversifying.
- Increased emphasis on CI rehabilitation and surgical techniques warrants ongoing monitoring.

01:16Clinical Trials
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

01:11Clinical Trials: Overview
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
01:13The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
