儿童突发性感音神经性聋发病特点分析

Sudden sensorineural hearing loss in children

目的 :探讨儿童突发性感音神经性聋 (突发性聋 )的发病特点 ,以指导临床诊断与治疗。方法 :总结2 1例 14岁以下突发性聋患儿 (儿童组 )的临床表现及预后等 ,并与 6 7例成年突发性聋 (对照组 )进行对比分析。结果 :儿童组中 11例 (5 2 .4 % )查到可能的病因 ,其中腮腺炎 4例 (19% )、上呼吸道感染 3例 (14 .3% )、耳毒性药物中毒 2例 (9.5 % )、声损伤和代谢性脑病各 1例 ;对照组 19.4 %找到可疑的病因。入院时儿童组听力受损平均88.6dB ,对照组 80 .2dB ,两组差异有统计学意义 (P <0 .0 5 ) ;治疗后儿童组听力平均提高 14 .3dB ,对照组提高37.8dB ,两组差异有统计学意义 (P <0 .0 5 )。结论 :儿童突发性聋的特点多有明确病因 ,其中以病毒感染多见 ,其耳聋程度重 。

Objective:To study the clinical features of the sudden sensorineural hearing loss (SSHL) in children.Method:Twenty-one children patients with SSHL and sixty-seven adult patients with SSHL as controls were investigated.Result:The possible causes were identified in 11 children cases ( 52.4%) as 4 mumps, 3 upper respiratory tract infections, 2 ototoxicity from aminoglycoside antibiotics, 1 noise exposure and 1 genetic metabolic encephalopathy.Conclusion:The hearing impairment was more severe and the prognosis was more poor in chidren with SSHL than that in the adults with SSHL.
