Pharyngeal reflux (PR) events are not significantly more common in patients with reflux laryngitis than in healthy individuals. Current diagnostic methods lack reliability for confirming gastric reflux in suspected cases.

Area of Science:

  • Gastroenterology
  • Otolaryngology
  • Digestive Diseases

Background:

  • Reflux laryngitis is often suspected to be caused by gastric reflux.
  • Pharyngeal reflux (PR) events are a key indicator of potential reflux.

Purpose of the Study:

  • To compare the prevalence of pharyngeal reflux events in patients with reflux laryngitis versus normal controls.
  • To evaluate the diagnostic utility of PR events in reflux laryngitis.

Main Methods:

  • Systematic review of prospective studies using 24-hour double-probe pH monitoring.
  • Inclusion of studies with normal controls and patients diagnosed with reflux laryngitis.

Main Results:

  • Eleven studies (192 controls) and 13 studies (512 patients) were analyzed.

  • PR events detected in 22.9% of controls and 38.3% of patients.
  • No significant difference in PR event prevalence between groups (P=0.079).

    • Conclusions:

    • A minority of reflux laryngitis patients exhibit PR events.
    • Prevalence of PR events does not significantly differ between patients and controls.
    • Reliable confirmation of gastric reflux in suspected laryngitis remains challenging, questioning current concepts.
