However, little knowledge is available for this new device. <jats:bold>Purpose<\/jats:bold>\u2003The aim of this study was to establish the\n knowledge of CCHAs and suggest their indication. <jats:bold>Research Design<\/jats:bold>\u2003Correlational study. <jats:bold>Study Sample<\/jats:bold>\u2003A total 256 patients were registered. <jats:bold>Data Collection and Analysis<\/jats:bold>\u2003The fitting of CCHAs was surveyed in nine institutions. The outcomes were assessed\n by audiometric tests. The patients were classified into seven groups, depending on the ear conditions. The clinical characteristics, assessment results, and purchase rates were compared among the groups. The assessment results of CCHAs were also compared with those of previously used hearing\n aids. <jats:bold>Results<\/jats:bold>\u2003Most patients who used CCHAs were classified into the bilateral closed (aural atresia or severe stenosis) ear (<jats:italic>n<\/jats:italic>\u2009=\u200965) or unilateral closed ear (<jats:italic>n<\/jats:italic>\u2009=\u2009124) groups. The patients in these groups achieved good benefits that\n resulted in a high purchase rate. The bilateral continuous otorrhea group also supported a high purchase rate, although the benefits of CCHAs were not always excellent. In contrast, the purchase rate was poor in the patients who could use air conduction hearing aids (ACHAs) without absolute\n problems. As for using a CCHA as a contralateral routing of signals hearing aid, the benefits depended on the patients. <jats:bold>Conclusions<\/jats:bold>\u2003CCHAs are considered as a great option not only to the patients with closed ears but also to those who had difficulties in ACHAs usage.<\/jats:p>","DOI":"10.1055\/s-0041-1728758","type":"journal-article","created":{"date-parts":[[2021,6,3]],"date-time":"2021-06-03T23:28:19Z","timestamp":1622762899000},"page":"386-392","source":"Crossref","is-referenced-by-count":17,"title":["Cartilage
