Reflux laryngitis: pathophysiology, diagnosis, and management

Area of Science:

• Otolaryngology
• Gastroenterology
• Digestive Health

Background:

• Gastroesophageal reflux disease (GERD) is frequently linked to various laryngeal conditions.
• Reflux laryngitis is a common manifestation, potentially caused by direct acid and pepsin exposure.
• The causal relationship and diagnostic methods for GERD-related laryngeal disorders remain debated.

Purpose of the Study:

• To explore the association between GERD and laryngeal conditions, specifically reflux laryngitis.
• To review the proposed mechanisms of laryngeal injury in GERD patients.
• To assess the diagnostic clarity and treatment effectiveness for reflux laryngitis.

Main Methods:

• Literature review examining studies on GERD, reflux laryngitis, and laryngeal symptoms.
• Analysis of proposed mechanisms, including direct acid and pepsin contact.
• Evaluation of existing diagnostic approaches and the efficacy of empiric treatment.

Main Results:

• Studies suggest a link between GERD and reflux laryngitis, but evidence on cause and effect is conflicting.
• Direct acid and pepsin contact is the most probable mechanism for laryngeal injury.
• Empiric treatment for reflux laryngitis has demonstrated effectiveness in some studies, but lack of controlled trials limits conclusions.

Conclusions:

• The association between GERD and reflux laryngitis is recognized, though definitive causal links and optimal diagnostic strategies require further investigation.
• Empiric treatment appears beneficial, highlighting the need for controlled clinical trials to validate its efficacy and establish diagnostic guidelines.
