Paradoxical vocal cord dysfunction (PVCD) in children is more prevalent in girls and linked to social stressors. Many exhibit laryngeal changes associated with gastroesophageal reflux disease, warranting prompt evaluation and treatment.

Area of Science:

  • Otolaryngology
  • Pediatric Pulmonology
  • Speech-Language Pathology

Background:

  • Paradoxical vocal cord dysfunction (PVCD) is a complex condition affecting vocal cord function.
  • Understanding demographic and videolaryngoscopic features in pediatric PVCD is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate the demographic characteristics of juvenile patients diagnosed with PVCD.
  • To analyze videolaryngoscopic findings in a cohort of young individuals with PVCD.
  • To identify potential associations between PVCD, social stressors, and laryngeal findings.

Main Methods:

  • Retrospective case series analysis of videolaryngoscopic tapes and medical charts.
  • Evaluation of 22 patients aged 18 years and younger with confirmed PVCD.

  • Assessment of demographic data and specific videolaryngoscopic parameters including laryngeal anatomy and vocal cord motion.

    • Main Results:

    • The study identified a higher prevalence of PVCD in girls (18 out of 22).
    • Significant social stressors, particularly related to organized sports, were noted in 12 patients.
    • Nineteen patients presented with posterior laryngeal changes often associated with gastroesophageal reflux disease (GERD).
    • Abnormal true vocal cord adduction during quiet respiration was observed in 12 patients.

    Conclusions:

    • Juvenile PVCD is more common in girls and associated with social stresses.
    • Laryngeal changes typical of GERD are frequently observed in pediatric PVCD patients.
    • Abnormal vocal cord adduction during respiration is a common finding.
    • Recommendations include initial laryngoscopy in asymptomatic children and considering empiric GERD treatment.
