Résumé
Objective To study and analyze the diagnostic value of auditory brainstem response (ABR) and distortion product otoacoustic emission (DPOAE) in infants with secretory otitis media.Methods From June 2016 to June 2018,65 infants (120 ears) with secretory otitis media who were treated at the First People's Hospital of Taizhou were selected.All the 120 ears were diagnosed by ABR wave test and DPOAE test machine.The results of different diagnostic methods were observed and compared.Results Among 65 cases (120 ears),60 ears (50.00%) with mildly abnormality,43 ears (35.83%) with moderate abnormality and 17 ears (14.17%) with normal ABR wave Ⅴresponse threshold.There was no statistically significant difference in Ⅰ-Ⅴwave interval between the mild abnormal group and the normal group ( P ＞0.05 ), but Ⅰ -Ⅴ wave interval in the moderate abnormal group [( 4.27 ± 0.27)ms in moderate abnormal group ] was significantly shorter than that in the normal group [(4.75 ±0.31) ms] and the mild abnormal group [(4.73 ±0.21)ms],the differences were statistically significant (t＝5.949,9.722,all P＜0.05).TheⅤresponse threshold of bone -guided ABR wave was normal in 108 ears(90.00%,108／120).TheⅤlatency of bone guided wave was (8.16 ±0.22) ms,and abnormal in 12 ears (10.00%,12／120).With the increase of the gas conduction reaction threshold ,the bone conduction ABR reaction threshold also increased ,but it was not as obvious as the air conduction.The wave Ⅴ latency in the normal BRT group was significantly lower than that in the abnormal group ( compared with mild abnormal group , t ＝17.400,P ＜0.05;compared with moderate abnormal group,t＝130.015,P＜0.05).DPOAE test failed 86 ears (71.67%,86／120),passed through 34 ears (28.33%,34／120).Conclusion The latency of ABR wave I is sensitive to the diagnosis of secretory otitis media in infants.The combination of DPOAE and ABR is helpful to the early diagnosis of the disease.ABR and DPOAE tests have high value and are worthy of popularizing in clinic.
