Most patients with poor development in their hearing function have had a severe microtia. Conventional methods to improve hearing function are bone conduction and bone anchored hearing aids. Cartilage conduction hearing aids (CCHA) represents a new amplification method. This study assessed the outcomes and evaluated the impact and its safety in the patients with microtia and aural atresia whose hearing dysfunction did not improve after surgery for ear reconstruction in our hospital. Hearing functions were evaluated with pure tone audiometry or sound field testing by behavioral audiometry and speech audiometry before and after CCHA fitting. As a result, there was a significant difference between unaided and aided thresholds (p &lt; 0.001). Speech recognition threshold and speech discrimination level also significantly improved with CCHA. The average functional gains of 14 ears were 26.9 \u00b1 2.3 dB. Almost all parents of the patients reported satisfaction with the performance of CCHA, and daily communication in children with hearing loss also became better than usual.<\/jats:p>","DOI":"10.3390\/audiolres11030038","type":"journal-article","created":{"date-parts":[[2021,8,13]],"date-time":"2021-08-13T05:34:46Z","timestamp":1628832886000},"page":"410-417","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Clinical Trial for Cartilage Conduction Hearing Aid in Indonesia"],"prefix":"10.3390","volume":"11","author":[{"given":"Ronny","family":"Suwento","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Cipto Mangunkusumo Hospital\u2014Faculty of Medicine, Universitas Indonesia, Jakarta 10430, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9332-8563","authenticated-orcid":false,"given":"Dini Widiarni","family":"Widodo","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Cipto Mangunkusumo Hospital\u2014Faculty of Medicine, Universitas Indonesia, Jakarta 10430, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tri Juda","family":"Airlangga","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Cipto Mangunkusumo Hospital\u2014Faculty of Medicine, Universitas Indonesia, Jakarta 10430, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Widayat","family":"Alviandi","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Cipto Mangunkusumo Hospital\u2014Faculty of Medicine, Universitas Indonesia, Jakarta 10430, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keisuke","family":"Watanuki","sequence":"additional","affiliation":[{"name":"RION Co., Tokyo 185-8533, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoko","family":"Nakanowatari","sequence":"additional","affiliation":[{"name":"RION Co., Tokyo 185-8533, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Hosoi","sequence":"additional","affiliation":[{"name":"Nara Medical University, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0000-1041","authenticated-orcid":false,"given":"Tadashi","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Nara Medical University, Kashihara 634-8522, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,13]]},"reference":[{"key":"ref_1","first-page":"485","article-title":"Treatment of Microtia: Past, Present and Future","volume":"34","author":"Sanjib","year":"2015","journal-title":"J.
