Work-related laryngeal syndromes

Area of Science:

• Occupational Medicine
• Laryngology
• Pulmonology

Background:

• Nonorganic laryngeal dysfunction can mimic asthma, presenting a diagnostic challenge in patients with work-associated respiratory symptoms.
• Occupational exposures are increasingly recognized as potential triggers for laryngeal dysfunction.

Purpose of the Study:

• To review recent literature on the association between nonorganic laryngeal dysfunction and occupational exposures.
• To highlight the importance of considering laryngeal dysfunction in the differential diagnosis of work-related respiratory conditions.

Main Methods:

• Literature review of recent studies on nonorganic laryngeal dysfunction and occupational exposures.
• Analysis of clinical features, epidemiological data, and etiological theories of laryngeal dysfunction.

Main Results:

• Vocal cord dysfunction (VCD) is the most recognized form of nonorganic laryngeal dysfunction, though consensus on clinical features is lacking.
• Occupational irritants and high psychological stress are implicated in the onset and recurrence of laryngeal dysfunction.
• Laryngeal dysfunction has been observed in specific occupational groups, including military personnel and athletes.

Conclusions:

• Laryngeal dysfunction is a critical consideration for work-associated respiratory symptoms, especially with exposure to irritants or high stress.
• Clinicians should maintain a high index of suspicion for laryngeal dysfunction in at-risk individuals.
• Evidence-based guidelines are needed for diagnosing and managing laryngeal dysfunction, incorporating work-related factors.
