Vocal cord dysfunction can mimic asthma symptoms like wheezing and shortness of breath. Diagnosis involves history, lung tests, and laryngoscopy, with management including speech therapy and counseling.

Area of Science:

  • Pulmonology
  • Otolaryngology

Background:

  • Vocal cord dysfunction (VCD) presents as a differential diagnosis for patients with refractory wheezing and dyspnea, often misdiagnosed as asthma.
  • Understanding VCD is crucial for accurate diagnosis and effective treatment in respiratory distress cases.

Observation:

  • Clinical presentation of VCD can overlap significantly with asthma, posing diagnostic challenges.
  • Key diagnostic tools include detailed patient history, pulmonary function tests, and direct laryngoscopic visualization during symptomatic episodes.

Findings:

  • Direct visualization using a flexible laryngoscope during an acute attack is the most definitive method for diagnosing vocal cord dysfunction.
  • Differentiation from asthma relies on identifying specific laryngeal abnormalities rather than solely relying on spirometry.

Implications:

  • Accurate diagnosis of VCD allows for targeted management strategies, avoiding unnecessary asthma medications.
  • Multidisciplinary management involving speech therapy, respiratory support (e.g., helium-oxygen inhalation), and psychiatric counseling is essential for VCD patients.
