Area of Science:

  • Pulmonology
  • Otolaryngology
  • Respiratory Medicine

Background:

  • Vocal cord dysfunction (VCD) involves paradoxical vocal cord adduction during inspiration, causing airway obstruction.
  • VCD is frequently misdiagnosed as difficult-to-treat asthma, leading to significant patient morbidity.

Purpose of the Study:

  • To review current knowledge on VCD, focusing on its relationship with asthma.
  • To present a diagnostic algorithm and treatment options for VCD in patients with difficult-to-control asthma.

Main Methods:

  • Literature search of MEDLINE, PubMed, and Cochrane library.
  • Keywords: "vocal cord/vocal cord dysfunction and asthma".

Main Results:

  • Numerous conditions associated with VCD have been identified.
  • The link between asthma and VCD is well-established.
  • Most VCD patients present with poorly controlled asthma symptoms.

Conclusions:

  • A careful diagnostic approach is crucial for identifying VCD.
  • Effective management strategies can improve outcomes for patients with VCD and asthma.
