ENT Scope Findings Interpretation
Your endoscopy shows signs consistent with chronic laryngitis, most likely related to laryngopharyngeal reflux (LPR), characterized by moderate medial arytenoid effacement, laryngeal erythema, and mild interarytenoid (IA) thickening—findings that suggest chronic inflammation of the larynx.
What These Findings Mean
The key abnormal findings in your report are:
- Moderate effacement of the medial arytenoid: Flattening or loss of normal contour of the arytenoid cartilage structures
- Laryngeal erythema: Redness/inflammation of the laryngeal tissues
- Mild interarytenoid (IA) thickening: Swelling or tissue buildup in the space between the arytenoid cartilages
- Mucoid post-nasal drainage with waterfall effect: Mucus draining from the nasopharynx
The remainder of your examination is reassuringly normal—no masses, obstructions, pooling of secretions, or concerning lesions anywhere in the nose, nasopharynx, oropharynx, or hypopharynx.
Clinical Significance
These Findings Suggest Chronic Laryngitis
The combination of medial arytenoid changes, erythema, and interarytenoid thickening are classic laryngoscopic signs of chronic laryngitis 1. The interarytenoid mucosa abnormalities are particularly significant—mucosal lesions of the interarytenoid notch increase the odds of reflux-related laryngitis by 21-fold 2, 3.
Important Caveats About These Findings
However, there are critical limitations to interpreting these findings:
- Poor specificity: These same findings (erythema of the medial arytenoid, posterior commissure changes, and interarytenoid abnormalities) have been documented in healthy volunteers without reflux symptoms 1
- Poor reliability: Studies show moderate to poor inter-rater reliability for identifying edema and erythema of the vocal folds and arytenoids, with results varying based on whether rigid or flexible laryngoscopy was used 1
- One large study of 1,209 patients found no difference in interarytenoid bar findings, arytenoid erythema, or posterior commissure changes between GERD patients and controls 4
What's Reassuring
No worrisome features are present: There are no masses, ulcerations, significant vocal fold abnormalities (no pseudosulcus vocalis or posterior commissure thickening), or pooling of secretions that would suggest malignancy, vocal fold paralysis, or other serious pathology 5.
Clinical Approach
If You Have Voice Symptoms (Hoarseness, Throat Clearing, Chronic Cough)
Anti-reflux medication may be considered as a treatment option 1. The AAO-HNS guidelines state that clinicians may prescribe anti-reflux medication for patients with hoarseness AND signs of chronic laryngitis (which you have) 1.
The evidence shows:
- Abnormalities of the interarytenoid mucosa and true vocal folds were predictive of improvement in laryngeal symptoms with PPI treatment 1
- However, randomized trials show mixed results—some studies found no benefit in symptom scores despite laryngoscopic improvement 1
If You Have NO Voice or Reflux Symptoms
Do not start anti-reflux medications empirically 1. The guidelines explicitly recommend against prescribing anti-reflux medications for patients without signs or symptoms of GERD, given known adverse effects (increased fracture risk, vitamin B12 deficiency, iron deficiency anemia, pancreatitis risk) and limited evidence of benefit 1.
What NOT to Do
Avoid oral corticosteroids—the AAO-HNS guidelines recommend against routinely prescribing oral corticosteroids for hoarseness, based on absence of clinical benefit and documented adverse events 1.
Bottom Line
Your findings represent mild-to-moderate chronic laryngeal inflammation. While suggestive of reflux-related changes, these findings alone are not diagnostic and can be seen in normal individuals. The clinical decision to treat should be based on your symptoms (hoarseness, throat clearing, chronic cough, globus sensation) rather than the laryngoscopic findings alone. Most importantly, there are no concerning features suggesting malignancy or other serious pathology requiring urgent intervention.
