This study was done to measure the outcomes of hearing aid (HA) and cochlear implantation (CI) in case of congenital non syndromic severe to profound sensorineural hearing loss (SNHL) by using aided audiometry (AA), categories of auditory perception (CAP) score and speech intelligibility rating (SIR) scale. The objectives were to find out the effective management options available for bilateral severe to profound SNHL, to study the impact of age of CI on language development and to study the outcome of HA and CI. Patients with congenital severe to profound SNHL were included in the study. Initially the case history of the participants was taken then they underwent audiological tests to confirm hearing loss. To assess the outcomes of HA and CI, they were initially fitted with high gain digital behind the ear HA, then underwent auditory verbal therapy for twelve months, after that AA, CAP and SIR test done to measure the outcomes of HA and similar hierarchy followed for CI. The results showed that with HA, the benefit is very limited whereas with CI the benefit is significant. The average SIR score of HA and CI are 1 and 3.16 and average CAP score are 0.83 and 7.8 respectively. The study shows that the CI is one of the most effective management options available for severe to profound SNHL and found that early intervention followed by early detection of hearing loss helps in achieving better speech and language skills.
本研究旨在通过使用助听测听法（AA）、听觉感知类别（CAP）评分和言语可懂度评级（SIR）量表，来衡量先天性非综合征性重度至极重度感音神经性听力损失（SNHL）患者使用助听器（HA）和人工耳蜗植入（CI）的效果。其目的是找出可用于双侧重度至极重度SNHL的有效管理方案，研究人工耳蜗植入年龄对语言发育的影响，并研究助听器和人工耳蜗植入的效果。先天性重度至极重度SNHL患者被纳入本研究。最初记录参与者的病史，然后他们接受听力学测试以确诊听力损失。为评估助听器和人工耳蜗植入的效果，他们最初佩戴耳背式高增益数字助听器，随后接受为期十二个月的听觉言语治疗，之后进行助听测听法、听觉感知类别和言语可懂度评级测试以衡量助听器的效果，人工耳蜗植入也遵循类似流程。结果显示，使用助听器时获益非常有限，而使用人工耳蜗植入时获益显著。助听器和人工耳蜗植入的平均言语可懂度评级得分分别为1和3.16，平均听觉感知类别得分分别为0.83和7.8。该研究表明，人工耳蜗植入是重度至极重度SNHL最有效的管理方案之一，并且发现听力损失的早期检测并随后进行早期干预有助于获得更好的言语和语言技能。
