Abstract：
OBJECTIVE: To evaluate the rate of loss to follow-up in a cochlear implant program from the public health system in Southern Brazil as well as the characteristics of hearing loss, sociodemographic, sociocultural and the development of oral language in children with prelingual deafness.
METHODS: Retrospective cohort study with children who underwent CI surgery between 2010 and 2020. Data was collected through of interviews and review of medical records. The language development assessment was performed using the MUSS, MAIS and IT-MAIS scales. For the classification of language development, we used as parameters the values (mean ± SD) found in a previous national study. From those values, the Z-score for each patient at each hearing age (time of experience with the cochlear implant) was calculated.
RESULTS: Of the 225 children implanted between 2010-2020, 129 were included in this study. The rate of loss to follow-up in the program was 42.6%. The mean age at first surgery was 40.5 (±16.9) months, with 77.5% of patients having received a unilateral implant. Language results below the expected for hearing age (CONCLUSIONS: Most patients had an elevated mean age at cochlear implantation and there was a high rate of loss to follow-up and low attendance to speech and programming sessions. An overall poor language performance was found for this pediatric cochlear implant program from the public health system in Southern Brazil.
METHODS: Level 3 (Non-randomized cohort study).

摘要：
目的：评估巴西南部公共卫生系统的人工耳蜗植入计划的随访损失率以及听力损失的特征，社会人口统计学，社会文化与语言前耳聋儿童口语的发展。
方法：对2010年至2020年接受CI手术的儿童进行回顾性队列研究。数据是通过访谈和病历审查收集的。语言发展评估是使用MUSS进行的，MAIS和IT-MAIS量表。对于语言发展的分类，我们使用在之前的国家研究中发现的值(平均值±SD)作为参数.从这些价值观中,计算每位患者在每个听力年龄(人工耳蜗植入的经验时间)时的Z评分.
结果：在2010-2020年期间植入的225名儿童中，有129名被纳入本研究。该计划的随访失用率为42.6％。首次手术的平均年龄为40.5（±16.9）个月，77.5%的患者接受了单侧植入物。在59.7％的样本中，语言结果低于MAIS评分的预期听力年龄（结论：大多数患者在人工耳蜗植入术时平均年龄升高，随访损失率高，演讲和编程课程出勤率低。在巴西南部的公共卫生系统中，这种小儿人工耳蜗植入计划的总体语言表现不佳。
方法：第3级（非随机队列研究）。
