前言：颈前庭诱发肌源性电位是一种用于耳神经科检查的检查方法。它通过声刺激激活囊状黄斑引起的肌肉反应来验证前庭功能的完整性。成人的正常标准已经建立，但是，很少有发表的数据在childhood.Objective：建立正常标准前庭肌源性反应的儿童没有neurotological complaints.Methods：这项研究的设计是一个队列与横断面分析。样本包括30名受试者，15名女性（50%）和15名男性（50%）。结果：受试者的年龄范围为8至13岁，平均10.2（+/- 1.7）。P1峰潜伏期平均为17.26（+/- 1.78）ms，平均振幅为49.34（+/- 23.07）μ V，N2峰潜伏期平均为24.78（+/- 2.18）ms，平均振幅为66.23（+/- 36.18）μ V。P1-N2平均振幅为115.6（+/- 55.7）mu V。当按性别或偏侧性进行比较时，没有统计学显著差异。我们建立了正常值的颈部肌源性前庭反应的儿童8至13岁之间没有神经耳疾病的投诉。(C)2015年巴西耳鼻喉科和颈面部手术协会。出版社：Elsevier Editora Ltda All rights reserved.
Introduction: Cervical vestibular evoked myogenic potential is a test used in neurotological examination. It verifies the integrity of vestibular function through a muscular response evoked by an acoustic stimulation which activates the saccular macula. Normal standards in adults have been established, however, there are few published data on the normal responses in children.Objective: To establish normal standards for vestibular myogenic responses in children without neurotological complaints.Methods: This study's design is a cohort with cross-sectional analysis. The sample consisted of 30 subjects, 15 females (50%) and 15 males (50%).Results: The age of the subjects ranged between 8 and 13 years, with a mean of 10.2 (+/- 1.7). P1 peak showed an average latency of 17.26 (+/- 1.78) ms and a mean amplitude of 49.34 (+/- 23.07) mu V, and the N2 peak showed an average latency of 24.78 (+/- 2.18) ms and mean amplitude of 66.23 (+/- 36.18) mu V. P1-N2 mean amplitude was 115.6 (+/- 55.7) mu V. There were no statistically significant differences when comparing by gender or by laterality.Conclusion: We established normal values of cervical myogenic vestibular responses in children between 8 and 13 years without neurotological complaints.
