【目的】了解听力损失婴儿的听力变化趋势,为正确有效干预提高依据。【方法】对101例(173耳)3个月内初次听性脑干反应(auditory brainstemresponse,ABR)疑为听力损失的婴儿在3个月后进行ABR追踪复查。【结果】第1次ABR检查,平均阈值(50.91±14.46)dBnHL,第2次ABR检查,平均阈值降为(39.57±19.74)dBnHL,差异有统计学意义。有121耳阈值减低,29耳不变,23耳增加,轻中度者分级程度转为正常78耳,占45.1%,8例9耳分级程度加重,极重度者阈值基本未改变。【结论】对于初次听力诊断疑为轻中度听力损失者,应进行每3个月1次的听力学监测和跟踪随访,重度以上的听力损失者3月龄的早期诊断和6月龄的早期干预是可行。
【Objective】 To understand the hearing changes in infants with hearing loss and to provide a basis for correct and effective intervention. 【Methods】 A total of 101 infants (173 ears) undergoing auditory brainstem response (ABR) for the first time within 3 months were retrospectively analyzed by ABR after 3 months. 【Results】 The first ABR examination showed that the average threshold (50.91 ± 14.46) dBnHL and the second ABR examination, the average threshold decreased to (39.57 ± 19.74) dBnHL, the difference was statistically significant. There are 121 ears reduced, 29 ears unchanged, 23 ears increased, mild to moderate degree of grading to 78 ears, accounting for 45.1%, 8 cases of 9 ears increased grading, extremely severe threshold did not change. 【Conclusion】 For patients with mild to moderate hearing loss who are suspected to be diagnosed with primary hearing, audiological monitoring and follow-up should be conducted once every 3 months. Early diagnosis of 3-month-old patients with severe hearing loss and early diagnosis of 6-month-old Intervention is feasible.
