This study established normative electroglottography (EGG) data for children aged 3-16. The findings show EGG is well-tolerated and provides valuable pediatric vocal function data.

Area of Science:

  • Laryngology and Speech Science
  • Pediatric Voice Assessment
  • Biomedical Engineering

Background:

  • Establishing normative voice data is crucial for diagnosing and treating pediatric voice disorders.
  • Electroglottography (EGG) offers a non-invasive method for assessing vocal fold function.
  • Limited normative EGG data exists for the pediatric population.

Purpose of the Study:

  • To establish normative electroglottography (EGG) data in the pediatric population.
  • To assess the feasibility and tolerance of EGG in children.
  • To provide a baseline for pediatric voice analysis.

Main Methods:

  • A clinical study involving 164 children (aged 3-16 years) with normal voices.
  • Electroglottography (EGG) recordings were obtained and analyzed using commercial software.

  • Key acoustic parameters including fundamental frequency, jitter, and quotient measures were evaluated.

    • Main Results:

    • Normative EGG data were successfully established for children aged 3 to 16 years.
    • Jitter, open quotient, closing quotient, and opening quotient showed no significant age-related dependence.
    • Children tolerated the EGG procedure well, indicating its suitability for pediatric use.

    Conclusions:

    • Electroglottography (EGG) is a well-tolerated and feasible procedure for children as young as 3 years.
    • The established normative data can aid clinicians in non-invasively documenting pediatric vocal function.
    • EGG may be particularly valuable for monitoring treatment outcomes in pediatric voice disorders, especially in cases difficult to examine endoscopically.
