雙耳語音感知不對稱對植有人工耳蝸的青少年之聲源定位、口語能力與讀寫能力的影響

// The Effect of Between-Ear Speech Perception Asymmetry on Localization, Spoken Language, and Literacy for Adolescents With Cochlear Implants

在80名早期植入人工耳蝸(CI)青少年中，雙耳語音感知不對稱（左右耳敏感度差）預測定位能力下降｜但對口語與閱讀無顯著影響；雙側CI優於電聲混合（bimodal：一側CI+助聽器）在定位表現｜臨床建議：量測不對稱度以指導裝置選擇與雙側植入時機

// The study tested whether between-ear speech-perception asymmetry affects localization, spoken language, and reading in 80 adolescents with early cochlear implants, using localization, unilateral speech, language and reading tests plus PCA composites and hierarchical regression. Greater between-ear asymmetry predicted poorer localization but had no effect on spoken language or reading; bilateral CI users localized better than bimodal users. Longer acoustic (bimodal) experience increased asymmetry and reduced localization, although children with better residual hearing gained localization and language benefits from early acoustic hearing. Clinically, measured asymmetry should inform device recommendations and timing of bilateral implantation.
