目的:分析新生儿普遍听力筛查中3个月内诊断为听力障碍婴儿其听力恢复正常的原因。方法:2001年11月~2005年6月在上海市出生并接受新生儿普遍听力筛查未通过者,转至上海市儿童听力障碍诊治中心接受听力学评估,均在出生3个月内诊断为听力障碍,并进行听力学跟踪随访至少6个月,对听力恢复正常者进行分析。结果:出生3个月内诊断为听力障碍者681例,随访6~24个月听力恢复正常者94例(115耳),占13.8%。听力恢复正常者中发现有鼓室积液56例(64耳),占59.6%;未发现有明确器质性原因者38例(51耳),占40.4%。听力恢复正常115耳中听力障碍轻度105耳,占91.3%;中度8耳,占7.0%;中重度2耳,占1.7%;重度和极重度无恢复正常者。结论:出生3个月内诊断有听力障碍的患儿,随年龄增长其听力恢复正常的可能性以轻、中度聋为大。恢复原因主要是分泌性中耳炎自愈和听中枢生理性发育逐渐成熟。
PURPOSE: To analyze the causes of normal hearing recovery in infants diagnosed with hearing impairment within 3 months of neonatal universal hearing screening. METHODS: From November 2001 to June 2005, those who were born in Shanghai and who did not receive universal neonatal screening tests were referred to Shanghai Children’s Hearing Impaired Center for audiological assessment and were diagnosed within 3 months of birth as Hearing impairment, and follow-up audiology follow-up at least 6 months, to analyze the normal hearing recovery. Results: 681 cases diagnosed as hearing impaired within 3 months after birth were followed up for 94 cases (115 ears), accounting for 13.8% of normal hearing recovery in 6 ~ 24 months. 56 cases (64 ears) of tympanic effusion were found in those with normal hearing recovery, accounting for 59.6%. There were 38 cases (51 ears) without clear organic cause, accounting for 40.4%. Hearing recovery was normal 115 Ear hearing weakness was mild 105 ears, accounting for 91.3%; moderate 8 ears, accounting for 7.0%; moderate and severe 2 ears, accounting for 1.7%; severe and extremely severe without recovery. CONCLUSION: Children with hearing impairment within 3 months of birth have mild to moderate deafness as their hearing loss is normal with age. The main reason is the recovery of secretory otitis media and listen to the central physiological development of mature.
