OBJECTIVES/HYPOTHESIS: Unilateral cochlear implantation has emerged as a widely accepted procedure to treat severe to profound hearing loss, but many studies have reported benefits in terms of speech comprehension when listeners with residual low-frequency hearing in the nonimplanted ear use a hearing aid.
Retrospective study.
In this study, we analyzed the speech performance and satisfaction of bimodal hearing according to the residual low-frequency hearing level in the nonimplanted ear. Based on low-frequency pure-tone audiometry (average of 250 Hz and 500 Hz) in the nonimplanted ear, we classified individuals into three groups as follows: group A (under 70 dB), group B (71-90 dB), and group C (over 91 dB). Listeners were tested using the Word Recognition Score, the Korea-Central Institute for Deaf sentence recognition test, and the Korean version of the Hearing Handicap Inventory for the Elderly questionnaire.
We observed a bimodal benefit when the residual low-frequency threshold was less than 70 dB HL and a greater satisfaction with bimodal hearing compared to cochlear implant alone, when the residual low-frequency threshold was less than 70 dB HL.
This study supports the benefits of bimodal hearing in listeners with bilateral severe to profound sensorineural hearing loss as standard clinical practice, when the residual low-frequency hearing threshold is under 70 dB in the nonimplanted ear.

目的/假设：单侧人工耳蜗植入已成为治疗重度至极重度听力损失的一种广泛接受的手术方法，但许多研究报告称，未植入耳有低频残余听力的听力者使用助听器时，在言语理解方面会有获益。
回顾性研究。
在本研究中，我们根据未植入耳的残余低频听力水平分析了双耳选配助听器的言语表现和满意度。根据未植入耳的低频纯音听力测定（250Hz和500Hz的平均值），我们将个体分为以下三组：A组（低于70dB）、B组（71 - 90dB）和C组（高于91dB）。使用单词识别得分、韩国聋人中央研究所句子识别测试以及韩国版老年人听力障碍问卷对听力者进行测试。
当残余低频阈值低于70dB HL时，我们观察到双耳选配助听器的益处，并且当残余低频阈值低于70dB HL时，与单独使用人工耳蜗相比，双耳选配助听器的满意度更高。
本研究支持在未植入耳的残余低频听力阈值低于70dB时，对于双侧重度至极重度感音神经性听力损失的听力者，双耳选配助听器作为标准临床实践的益处。
