【摘要】 目的探讨婴儿巨细胞病毒(CMV)感染对婴儿听力损伤的影响。方法应用听觉脑干诱发电位(ABR),对40例CMV感染儿(感染组)及20例非感染儿(对照组),进行听力筛查及评估。结果感染组中40例46耳(57.50%)未通过,其中双耳未通过的有15例(37.5%),单耳未通过的有16例(40.0%),对照组中20例3耳(7.5%)未通过,均为单耳未通过。感染组听力损伤率为77.5%,对照组听力损伤率为15%。两组相比差异显著(χ2=21.0,P<0.01)。结论婴儿CMV感染是导致人类非遗传性先天性耳聋的主要原因,BAEP是早期发现CMV听路病变的敏感性、非损伤性检查,值得推广。更多还原

【Abstract】 Objective To investigate the impact of cytomegalovirus infection hepatitis on the hearing damage in infants.Methods By using the tools of auditory brain-stem response (ABR),the hearing ability of 40 infants with cytomegalovirus infection and 20 cases of no infection controls were screened.Results In the cytomegalovirus infection group,57.5 %(46/80)ears were not passed the tests,37.5%(15/40)two ears of them not passed the tests,40%(16/40)one ear of them not passed the tests; while in the controls,7.5% (3/20) ears were not passed the tests,and the whole of them was one ear not passed. There was significant difference between the infants with cytomegalovirus infection and controls (P<0.01).Furthermore,in infants with cytomegalovirus infection,77.5%(31/40)had hearing damage; in the controls,15%(3/40) had hearing damage.Conclusion The cytomegalovirus infection is one of the leading non-genetic causes of SNHL in children. BAEP is a kind of sensitive,harm less method. It can find hearing damage by CMV infection in early stage, which is worth to be popularized.更多还原
