The hearing thresholds and functional gain following CC-HA wear were synthesised. A one-way analysis of variance compared the differences in the hearing thresholds and functional gain at individual frequencies and in patients with a variety of pathological changes. The synchronised aided hearing threshold and functional gain at 2.0 kHz were significantly better than at 0.5, 1.0, and 4.0 kHz. There was no significant difference in the synchronised unaided hearing thresholds across individual frequencies between 0.5 and 4.0 kHz. The synchronised functional gain in patients with atresia was significantly greater than in patients with aural atresia or stenosis and middle ear pathologies with normal ear canals. The acceptability of CC-HAs in terms of purchase decision is influenced by the condition of the external auditory meatus and severity of hearing loss, with the highest purchase rate seen in patients with aural atresia or stenosis. CC-HAs\u2019 fitting procedure advantages and cosmetic considerations make these devices a viable and preferred choice for individuals with microtia and aural atresia. Additional research to evaluate the benefits towards emotional well-being is crucial to gain insights into the psychological impact of CC-HA use.<\/jats:p>","DOI":"10.3390\/audiolres13040055","type":"journal-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T05:43:12Z","timestamp":1691732592000},"page":"636-650","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Systematic Review of the Audiological Efficacy of Cartilage Conduction Hearing Aids and the Factors Influencing Their Clinical Application"],"prefix":"10.3390","volume":"13","author":[{"given":"Bei","family":"Li","sequence":"first","affiliation":[{"name":"Centre for Speech and Language Therapy and Hearing Science, Cardiff School of Sport and Health Sciences, Cardiff Metropolitan University, Cardiff CF5 2YB, UK"},{"name":"Department of Otolaryngology, Affiliated Hospital of North Sichuan Medical College, Nanchong 637000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sinyoung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Graduate Faculty of Interdisciplinary Research, University of Yamanashi, Yamanashi 400-8511, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zuwei","family":"Cao","sequence":"additional","affiliation":[{"name":"Centre for Rehabilitative Auditory Research, Guizhou Provincial People\u2019s Hospital, Guiyang 550002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuji","family":"Koike","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Intelligent Systems Engineering, Graduate School of Informatics and Engineering, The University of Electro-Communications, Chofu 182-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robin","family":"Joseph","sequence":"additional","affiliation":[{"name":"King Edward VII Hospital, Berkshire NHS Foundation Trust, Winsor SL4 3DP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamsin Holland","family":"Brown","sequence":"additional","affiliation":[{"name":"Cambridgeshire Community Services NHS Trust, Cambridge CB1 3DF, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Zhao","sequence":"additional","affiliation":[{"name":"Centre for Speech and Language Therapy and Hearing Science, Cardiff School of Sport and Health Sciences, Cardiff Metropolitan University, Cardiff CF5 2YB, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ball, M.J.
