To compare the hearing thresholds obtained with auditory brainstem response (ABR) and auditory steady state response (ASSR) audiometry in children with hearing loss.
Hearing thresholds were obtained by ABR and ASSR in children who presented with suspicion of deafness at Ear, nose & throat department of Al-Nafees Medical College Hospital Islamabad, between January to August 2018. The mean hearing thresholds obtained by two tests were compared within each category of severity of deafness. Time taken by both tests was also compared.
A total of 57 patients (114 ears) were included in the study. Among them 27 (47.4%) were male and 30 (52.6%) were female. The mean age of patients at presentation was 42 months (±30.9) with age range from one to 12 years. Mean hearing thresholds obtained by click ABR, chirp ABR, ASSR (1, 2, 4 kHz) & ASSR (0.5, 1, 2, 4 kHz) was 56.25 (±27.61), 58.88 (±27.44), 58.03 (±21.26) & 56.35 (±22.86) respectively. Mean thresholds were comparable between click ABR & ASSR (1, 2, 4 kHz) and between chirp ABR & ASSR (0.5, 1, 2, 4 kHz) in all degrees of hearing loss categories except in those patients with normal hearing thresholds. The mean time taken by clicks ABR, chirp ABR and ASSR were four minutes seven seconds, three minutes 15 seconds and 16 minutes and 7 seconds respectively.
Hearing thresholds obtained by ABR and ASSR are comparable in all categories of severity of hearing loss. The time taken by ABR is less as compared to ASSR.
比较听力损失儿童通过听性脑干反应（ABR）和听觉稳态反应（ASSR）测听获得的听阈。
2018年1月至8月期间，在伊斯兰堡纳菲斯医学院医院耳鼻喉科对疑似耳聋的儿童进行ABR和ASSR测听以获得听阈。在每个耳聋严重程度类别中比较两种测试获得的平均听阈。同时比较两种测试所需的时间。
共有57例患者（114耳）纳入研究。其中男性27例（47.4%），女性30例（52.6%）。患者就诊时的平均年龄为42个月（±30.9），年龄范围为1至12岁。短声ABR、短纯音ABR、ASSR（1、2、4kHz）和ASSR（0.5、1、2、4kHz）获得的平均听阈分别为56.25（±27.61）、58.88（±27.44）、58.03（±21.26）和56.35（±22.86）。除听力阈值正常的患者外，在所有听力损失程度类别中，短声ABR与ASSR（1、2、4kHz）之间以及短纯音ABR与ASSR（0.5、1、2、4kHz）之间的平均阈值具有可比性。短声ABR、短纯音ABR和ASSR的平均用时分别为4分7秒、3分15秒和16分7秒。
在所有听力损失严重程度类别中，ABR和ASSR获得的听阈具有可比性。与ASSR相比，ABR用时更少。
