Summary

This case study shows speech therapy effectively treating respiratory stridor caused by paradoxical vocal fold motion. Recognizing this functional breathing disorder is key for proper diagnosis and management.

Area of Science:

  • Otolaryngology
  • Pulmonology
  • Speech-Language Pathology

Background:

  • Respiratory stridor can be a challenging clinical presentation.
  • Functional respiratory disorders often mimic organic pathologies.
  • Paradoxical vocal fold motion (PVFM) is an underdiagnosed cause of upper airway obstruction.

Observation:

  • A patient presented with significant respiratory stridor, wheezing, and dyspnea.
  • Flexible fiberoptic videolaryngoscopy revealed paradoxical vocal fold adduction during inspiratory distress.
  • Normal vocal fold function was observed during quiet breathing and phonation.

Findings:

  • The patient's stridor and dyspnea were successfully resolved with targeted speech therapy.
  • This suggests a functional etiology for the observed respiratory symptoms.

  • Speech therapy interventions can effectively manage paradoxical vocal fold motion.

    • Implications:

    • Clinicians should consider functional stridor and paradoxical vocal fold motion in the differential diagnosis of respiratory distress.
    • Early recognition and appropriate treatment, such as speech therapy, can lead to significant patient improvement.
    • Further research into the pathophysiology and treatment of PVFM is warranted.
