Abstract
Introduction: In this study we investigated the effect of cochlear implantation on tinnitus in patients with post lingual bilateral profound hearing loss.
Methods: In this retrospective study, 66 post-lingual deaf patients over 18 years old who referred for cochlear implantation and complained of tinnitus were included. Patients were divided into two groups with residual hearing (in frequency 250-500 Hz) and without residual hearing. All data including age, gender, type of implants, type of surgery, cause of the disease, and information on the THI score before cochlear implantation, one month after cochlear implantation and one year after cochlear implantation was recorded and analyzed.
Results: Nine patients had residual hearing, while 57 patients did not. After one month and one year, in both groups, the mean THI score has decreased significantly (p-value = 0.001), but there was no significant difference in the mean THI score before surgery and one month and one year after surgery between two groups with and without residual hearing. There was no significant difference in tinnitus severity according to THI-grade between two groups. Also there was no significant difference in THI score and the cause of the hearing loss, type and insertion method of implantation, one month and one year after the surgery between two groups.
Conclusion: According to our results, the was no significant correlation between residual hearing and tinnitus score before surgery, one month and one year after the surgery.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
