This study aimed to determine if adolescents/young adults gained additional perceptual benefit from sequential bilateral cochlear implants within 12 months, and to document adaptation to the second implant. Assessments comprised a pediatric version of The Speech, Spatial and Qualities of Hearing Scale (SSQ), anecdotal reports of device use and daily listening, and the Adaptive Spondee Discrimination Test (AdSpon). All nine participants achieved full-time use of, a preference for, and superior daily listening with, bilateral implants. Eight participants were comfortable using the second implant alone, and two achieved similar daily listening with either implant alone. SSQ ratings were higher post-operatively for the majority of participants. AdSpon performance was superior bilaterally for five participants with noise ipsilateral to the first implant, but not contralateral. Unilateral performance with either implant was similar for one participant. A second implant may provide additional benefit up to 19 years of age, even with congenital hearing loss and >16 years between implants. Families and clinicians should understand the aspects of second-implant candidacy and post-operative use that are unique to adolescents/young adults.
本研究旨在确定青少年/年轻人在 12 个月内是否能从双侧序贯人工耳蜗植入中获得额外的感知益处，并记录对第二植入体的适应情况。评估包括儿童版言语、空间和听觉质量量表（SSQ）、设备使用和日常听力的轶事报告，以及自适应短句辨别测试（AdSpon）。所有 9 名参与者都实现了全时使用、对双侧植入体的偏好和优越的日常听力。8 名参与者能够舒适地单独使用第二个植入体，其中 2 名参与者单独使用任何一个植入体都能获得类似的日常听力。对于大多数参与者来说，术后 SSQ 评分更高。对于 5 名第一侧植入体同侧有噪声的参与者，AdSpon 双侧表现较好，但对侧则不然。对于一名参与者来说，单侧使用任何一个植入体的表现都相似。即使存在先天性听力损失和两次植入之间的时间间隔超过 16 年，第二植入体也可能在 19 岁之前提供额外的益处。家庭和临床医生应了解青少年/年轻人第二植入体候选和术后使用的独特方面。
