title: Cervical vestibular evoked myogenic potentials in children.
abstract: BACKGROUND
  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)μV, and the N2 peak showed an average latency of 24.78 (± 2.18)ms and mean amplitude of 66.23 (± 36.18)μV. P1-N2 mean amplitude was 115.6 (± 55.7)μV. There were no statistically significant differences when comparing by gender or by laterality.
  
  
  CONCLUSIONS
  We established normal values of cervical myogenic vestibular responses in children between 8 and 13 years without neurotological complaints.
