学龄前和学龄期BPV患儿临床特征比较

Clinical Analysis of Benign Paroxysmal Vertigo in preschool and school-age children

目的探讨学龄前和学龄期良性阵发性眩晕(BPV)患儿临床特征差异性。方法选取BPV患儿48例,通过眩晕问卷调查、听力学检查、前庭功能检查,对比分析学龄前和学龄期BPV患儿在临床表现、前庭功能的特点。结果 48例BPV患儿中男22例、女26例,年龄3~12岁,中位年龄7.0岁;学龄前患儿25例,学龄期患儿23例。学龄前及学龄期患儿临床表现为恶心、呕吐率分别为35.7%(10/28)和64.3%(18/28),平衡功能障碍率分别为85.7%(12/14)和14.3%(2/14),伴发头痛率分别为18.2%(2/11)和81.8%(9/11),学龄前和学龄期患儿恶心、呕吐率、平衡功能障碍率、伴发头痛率比较,差异有统计学意义(P均<0.05);辅助检查中纯音测听、声导抗、高刺激率ABR、前庭冷热气检查方面,学龄前和学龄期患儿比较,差异无统计学意义。结论学龄前和学龄期BPV患儿在临床表现、平衡障碍、伴发头痛方面有所不同。

Objective To explore the clinical characteristics of benign paroxysmal vertigo（ BPV） in preschool and school-age children. Methods Findings from 48 children with BPV,who completed vertigo questionnaires and underwent audiological and vestibular function examinations,were analyzed. Results The patients were 3-12 years old（ mean 7. 0） and included 22 boys and 26 girls. Twenty-five children were of preschool-age,while 23 were of school-age. The rates of nausea and vomiting in preschool and school-age children were 35.7%（ 10/28） and 64.3%（ 18/28）,balance dysfunction were 85.7%（ 12/14） and 14.3%（ 2/14）,and headache were 18.2%（ 2/11） and 81.8%（ 9/11）,respectively. The difference between the two groups for these three parameters was statistically significant. There was no statistically significant difference between pre-school and school-age children for pure tone audiometry,acoustic conduction,high stimulation rate ABR,and caloric test. Conclusion BPV in preschoolers and school-age children differs with regard to clinical presentation of symptoms such as nausea and vomiting,balance disorder,and headache.
