Air-And Bone-Conduction Auditory Brainstem Response in Children with Congenital External Auditory Canal Atresia
Wen-Xia Chen Yan Wang Ping Lu Yue HuangZheng-Min Xu<p><strong>Objective:</strong> This study aimed to determine the clinical value of air- and bone-conduction auditory
brainstem responses (ABRs) in children with congenital external auditory canal atresia (EACA).</p><p><strong> Methods:</strong> Air- and bone-conduction click-evoked ABRs in 38 children having congenital EACA
were compared with 34 children having normal hearing.</p><p><strong> Results:</strong> ABR threshold for air and bone conduction were 66.53 ± 7.12 and 12.55 ± 6.96
dBnHL, respectively, in children with congenital EACA, as well as 25.32 ± 2.66 and 10.71 ± 4.51
dBnHL, respectively, in children with normal hearing. The two groups showed statistical difference
in air-conduction ABR thresholds. Meanwhile, air–bone ABR threshold gap was greater in children
with EACA than in children with normal hearing, and bone-conduction ABR wave latencies did not
statistically differ between the two groups.</p><p><strong> Conclusion:</strong> Bone-conduction ABR is valuable in assessing the function of cochlea, auditory
nerve, and brainstem in individuals with congenital EACA. The study has important clinical value in
the objective differential diagnosis of conductive deafness with combined application of air- and boneconduction
ABRs.</p>
