Vocal cord dysfunction can cause upper airway obstruction, mimicking asthma. This study suggests a chronic, unremitting symptom syndrome may occur in some patients with this condition.

Area of Science:

  • Pulmonology
  • Otolaryngology
  • Respiratory Medicine

Background:

  • Functional upper airway obstruction is often attributed to vocal cord dysfunction (VCD).
  • VCD classically presents with paroxysmal symptoms that resemble acute asthmatic attacks.
  • The episodic nature of VCD symptoms can complicate diagnosis and management.

Observation:

  • This report details two cases of vocal cord dysfunction.
  • In these cases, the symptoms and signs of VCD exhibited minimal temporal variability.
  • The patients presented with persistent, rather than episodic, symptoms.

Findings:

  • The findings challenge the classical presentation of VCD as solely paroxysmal.
  • The study identifies a potential syndrome of chronic, unremitting symptoms associated with VCD.

  • This suggests VCD may manifest with greater symptom stability than previously recognized.

    • Implications:

    • This expands the clinical spectrum of vocal cord dysfunction.
    • It highlights the need to consider VCD in patients with chronic respiratory symptoms, even without clear episodic triggers.
    • Recognition of this chronic VCD syndrome can improve diagnostic accuracy and patient outcomes.
