To evaluate the effects of BCDs in UCHL, a systematic search was undertaken until May 2023 following the PRISMA guidelines. Among the 391 references, 21 studies met the inclusion criteria and were ultimately selected for review. Data on hearing thresholds, speech recognition, sound localization, and subjective questionnaire outcomes were collected and summarized. Moderate hearing threshold improvements were found in UCHL patients aided with BCDs. Their speech recognition abilities improved significantly. However, sound localization results showed wide individual variations. According to subjective questionnaires, BCDs had an overall positive influence on the daily life of UCHL patients, although several unfavorable experiences were reported by some of them. We concluded that the positive audiological benefits and subjective questionnaire results have made BCDs a credible intervention for UCHL patients. Before final implantations, UCHL patients should first go through a period of time when they were fitted with non-implantable BCDs as a trial.<\/jats:p>","DOI":"10.3390\/jcm12185901","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T09:11:18Z","timestamp":1694423478000},"page":"5901","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Effects of BCDs in Unilateral Conductive Hearing Loss: A Systematic Review"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0863-8709","authenticated-orcid":false,"given":"Xin-Yue","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liu-Jie","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"You-Zhou","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao-Yao","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ya-Ying","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8165-3622","authenticated-orcid":false,"given":"Chen-Long","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tian-Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Facial Plastic Reconstructive Surgery, ENT Institute, Eye and ENT Hospital, Fudan University, Shanghai 200031, China"},{"name":"NHC Key Laboratory of Hearing Medicine, Fudan University, Shanghai 200031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1016\/j.ijporl.2019.03.014","article-title":"A new adhesive bone conduction hearing system effectively treats conductive hearing loss in children","volume":"122","author":"Neumann","year":"2019","journal-title":"Int.
