Abstract

<p> Cartilage conduction hearing aids are a new type of hearing device launched in November 2017. They are effective in patients with aural atresia, and therefore, a great choice for amplification in such patients. Although their use has spread gradually, they are still not well known, in general. In order to make them more popular, the information sources which motivate patients to try cartilage conduction hearing aids were investigated. A total of 45 patients from our hospital participated in the study until February 2019. The information sources were classified as Doctor, Media (website or television), Patients Association, Family/Friend, Teacher, and Hearing Aid Store. The survey was conducted every three months, and changes in the information sources over time were also evaluated. Furthermore, subjects with aural atresia or stenosis of the ear canal were divided into binaural and monaural disorder groups, while the others were considered as one group. The differences in the information sources among the groups were evaluated. The results showed that patient associations were the most frequently reported source of information, being confirmed by approximately one-third of all responses. As for changes in information sources over time, although doctors were rarely reported as a source of information in the first one year, the frequency dramatically increased during the last three months. Hearing aid stores were reported only in the first six months, indicating the need to provide the stores again with information about the new hearing aids. Comparison of the results between the binaural and monaural disorder groups revealed that patient associations were more frequently reported as the source of information by the monaural disorder group. In the monaural disorder group, the number of cases increased after the first six months. In this study, most subjects were under 20 years of age. Therefore, effective approaches to encourage the use of cartilage conduction hearing aids among adult patients with aural atresia must be considered in the future.</p>
