Hearing benefits were evaluated by the word recognition score (WRS), speech reception threshold, the international outcome inventory for hearing aids (IOI-HA), and the Speech, Spatial, and Qualities of Hearing Test for Parent (SSQ-P). Sound localization was measured using broadband noise stimuli randomly played from seven loudspeakers at different stimulus levels [65, 70, and 75 dB sound pressure levels (SPLs)]. The average unaided WRS and speech-to-noise ratio (SNR) for UMA patients was 18.27 \u00b1 14.63 % and \u22125 \u00b1 1.18 dB SPL, and the average aided WRS and SNR conspicuously changed to 85.45 \u00b1 7.38 % and \u22127.73 \u00b1 1.42 dB SPL, respectively. The mean IOI-HA score was 4.57 \u00b1 0.73. Compared to the unaided condition, the mean SSQ-P score in each domain improved from 7.08 \u00b1 2.5, 4.86 \u00b1 2.27, and 6.59 \u00b1 1.4 to 8.72 \u00b1 0.95, 7.61 \u00b1 1.52, and 8.55 \u00b1 1.09, respectively. In the sound localization test, some children with UMA were able to detect sound sources quite well and the sound localization abilities did not deteriorate with the non-surgical BCD. Our study concludes that for children with UMA, the non-surgical BCD provided a definite benefit on speech recognition and high satisfaction without deteriorating their sound localization abilities. It is an efficient and safe solution for the early hearing intervention of these patients.<\/jats:p>","DOI":"10.3389\/fnins.2022.973735","type":"journal-article","created":{"date-parts":[[2022,8,26]],"date-time":"2022-08-26T09:54:11Z","timestamp":1661507651000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Characteristics of sound localization in children with unilateral microtia and atresia and predictors of localization improvement when using a bone conduction device"],"prefix":"10.3389","volume":"16","author":[{"given":"Yujie","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunli","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peiwei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinsong","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danni","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran","family":"Ren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouqin","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shusheng","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,8,25]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1007\/s10162-010-0235-2","article-title":"Improved horizontal directional hearing in bone conduction device users with acquired unilateral conductive hearing loss.","volume":"12","author":"Agterberg","year":"2011","journal-title":"J.
