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 ,预后较成人差 Objective: To investigate the incidence of sudden sensorineural deafness (sudden deafness) in children to guide clinical diagnosis and treatment. Methods: The clinical manifestations and prognosis of 21 children with sudden deafness under 14 years old (children group) were summarized and compared with 67 adult sudden deafness (control group). Results: Of the 11 children (5.2%) in the children group, the possible etiologies were found, including mumps in 4 cases (19%), upper respiratory tract infection in 3 cases (14.3%) and ototoxicity poisoning in 2 cases %), 1 case of acoustic damage and metabolic encephalopathy; 19.4% of control group found suspicious etiology. At admission, the children with hearing impairment had an average of 88.6dB in hearing loss and 80.2dB in control group, with significant difference between the two groups (P <0.05). After treatment, the average hearing ability of children increased by 14.3dB and that of control group increased by 37.8dB, The difference between the two groups was statistically significant (P <0.05). Conclusion: The characteristics of children with sudden deafness have more definite causes, of which the virus infection is more common, the degree of deafness is heavier, the prognosis is worse than that of adults
