【摘要】 目的:探究影响儿童良性阵发性位置性眩晕(benign paroxysmal positional vertigo, BPPV)在儿童眩晕中的诊断的相关因素。方法:回顾性分析2017年9月至2023年8月就诊于天津医科大学总医院听力眩晕诊疗中心的眩晕儿童(年龄<18岁)中BPPV的诊断占比，并对BPPV患儿一般资料、病史、首诊科室、受累半规管、治疗、预后及复发等临床特征及共病情况进行分析。采用SPSS 25.0软件进行统计学分析。结果:BPPV在眩晕儿童中占比为22.8%,不同年龄段眩晕儿童中BPPV占比存在差异(P<0.05),7～12岁组BPPV的确诊时病程较13～17岁组病程长(P<0.05)。72.3%(47/65)的患儿或家属能在就诊初期向医生提供BPPV典型位置性眩晕病史。49.2%的BPPV患儿存在共病(32/65),不同年龄组BPPV患儿存在共病的比例差异有统计学意义(P<0.05)。随着研究进展，儿童BPPV在眩晕儿童中诊断比例及将耳鼻喉科作为首诊科室的比例均呈现上升趋势(P<0.05)。儿童BPPV水平半规管的比例提高。BPPV患儿均进行了耳石复位治疗，治疗效果良好，复发率为12.3%(8/65),存在共病的BPPV患儿组的复发率为21.9%,高于无共病组(P<0.05)。结论:儿童BPPV具有病史不明确、共病比例高、共病患儿易复发、水平半规管受累比例高等临床特点。对于已经诊断为其他眩晕疾病的患儿亦不可忽视BPPV诊断试验，建议在条件允许下对眩晕患儿常规进行位置试验，防止儿童BPPV的漏诊。更多还原

【Abstract】 Objective: To explore relevant factors to accurately diagnose BPPV in vertigo children. Methods: A retrospective study was conducted on the proportion of BPPV in children(<18 years) with vertigo who visited the Hearing and Vertigo Diagnosis and Treatment Center of Tianjin Medical University General Hospital from September 2017 to August 2023. The clinical characteristics of BPPV children, including general demographics, medical history, first visit department, comorbidities, canal involvement, response to treatment, and incidence of recurrence, were analyzed. Data analysis was conducted using SPSS 25.0 software. Results: BPPV was diagnosed in 22.8% of patients seen for vertigo during the study period. There are differences in the proportion of BPPV diagnosis among children with dizziness in different age groups(P<0.05), and the diagnosis of BPPV in the 7-12-year-old group has a longer disease course than in the 13-17-year-old group(P<0.05). 72.3%(47/65) of patients or their families were able to provide a typical history of positional vertigo. 49.2%(32/65) of BPPV patients had comorbidities, and there were differences in the proportion of comorbidities among different age groups of BPPV patients(P<0.05). With the progress of study, the proportion of BPPV in children with vertigo has shown an upward trend, and the proportion of children with otolaryngology as the first diagnosis department has also increased(P<0.05). The proportion of horizontal semicircular canals in children with BPPV has increased. All BPPV patients underwent canalith repositioning maneuvers, with good treatment outcomes and a recurrence rate of 12.3%(8/65). The recurrence rate in the group of BPPV patients with comorbidities was 21.9%, which was higher than that in the group without comorbidities(P<0.05). Conclusion: Childhood BPPV has clinical characteristics such as unclear medical history, high proportion of comorbidities, easy recurrence in BPPV children with comorbidities and high proportion of horizontal semicircular canal involvement. For children diagnosed with other vertigo diseases, do not ignore the BPPV diagnostic test. It is recommended to perform routine position tests on children with vertigo if conditions permit to reduce missed diagnosis of BPPV in children.更多还原
