Presenting Complaint: Persistent Hoarseness

A 45‑year‑old high‑school teacher reports a rough, breathy voice that has lasted for four weeks. She notes the hoarseness is worst in the morning and improves slightly after speaking for a few minutes, but never returns to normal. No acute sore throat, fever, or recent upper‑respiratory infection preceded the change.

She describes a constant sensation of a lump in the throat (globus) and a dry, non‑productive cough that worsens after prolonged talking. There is no history of smoking, alcohol excess, or recent intubation. The patient denies weight loss, night sweats, or dysphagia.

Because the voice alteration has persisted beyond three weeks, the clinician classifies the problem as chronic laryngitis rather than an acute viral laryngitis, which typically resolves within seven to ten days.

Key Symptom Cluster: Voice Change, Throat Discomfort, and Cough

The hallmark of chronic laryngitis is a persistent alteration in vocal quality — hoarseness, breathiness, reduced pitch range, or vocal fatigue — lasting more than three weeks. Patients often report a "raspy" or "strained" voice that interferes with professional or social communication.

Associated throat symptoms include a dry or scratchy sensation, frequent throat clearing, and a feeling of mucus that cannot be cleared. A chronic, irritative cough — usually dry and worse at night or after voice use — accompanies the laryngeal inflammation in many cases.

Unlike acute laryngitis, systemic signs such as fever, malaise, or lymphadenopathy are absent. The symptom cluster points to ongoing irritation of the vocal folds rather than an infectious process.

  • Hoarseness or breathiness > 3 weeks
  • Globus sensation or throat dryness
  • Frequent throat clearing
  • Dry, irritative cough worse with voice use
  • Absence of fever or systemic illness

Clinical History Taking: Duration, Triggers, and Comorbidities

The clinician asks the patient to quantify voice use: she teaches five hours daily, projects her voice in a large classroom, and rarely uses amplification. She also reports occasional gastro‑esophageal reflux symptoms — heartburn after spicy meals — but no formal diagnosis of GERD.

Environmental exposures are reviewed: the classroom is climate‑controlled, but the air is dry during winter months. No occupational inhalants, allergens, or recent chemical exposures are identified. Medication list includes a low‑dose inhaled corticosteroid for mild asthma, which can contribute to laryngeal dryness.

A focused review of systems screens for autoimmune disease (rheumatoid arthritis, lupus), thyroid dysfunction, and neurological disorders (vocal fold paralysis). All are negative, narrowing the differential to inflammation from voice overuse, reflux, or chronic irritant exposure.

Physical Examination and Laryngoscopic Findings

The neck is palpated for thyroid enlargement or lymphadenopathy — none are found. Cranial nerve examination is normal, confirming intact vagal innervation to the larynx. Flexible nasolaryngoscopy is performed in the seated position after topical anesthesia.

The laryngoscopic view reveals bilateral vocal‑fold edema with a diffuse pink‑red discoloration, loss of the normal sharp medial edge, and a thin layer of mucus coating the folds. No discrete lesions, nodules, polyps, or ulcerations are seen. The ventricular folds are slightly thickened but mobile.

Stroboscopic light shows reduced mucosal wave amplitude and a slightly increased closed quotient, consistent with chronic inflammatory changes rather than a mass lesion. These findings satisfy the visual criteria for chronic laryngitis.

Diagnostic Criteria and Differential Diagnosis

Current guidelines define chronic laryngitis as persistent laryngeal inflammation with hoarseness lasting longer than three weeks, supported by laryngoscopic evidence of diffuse vocal‑fold erythema, edema, or mucus without a focal lesion. The diagnosis is clinical; no single laboratory test confirms it.

Key differentials include vocal‑fold nodules (usually symmetric, localized swellings), polyps (often unilateral, vascularized), reflux laryngitis (posterior commissure erythema, pachydermia), and early laryngeal carcinoma (irregular lesion, ulceration, fixation). The absence of a discrete mass and the bilateral, diffuse pattern favor chronic laryngitis.

If reflux is suspected, a trial of proton‑pump inhibitor therapy and lifestyle modification may be initiated, but the primary diagnosis remains chronic laryngitis until symptom resolution or further work‑up (e.g., pH monitoring) clarifies the contribution of gastro‑esophageal reflux.

Worked Example: From Symptom Onset to Confirmation

Step 1 – Timeline: The teacher notes hoarseness beginning after a week of parent‑teacher conferences with prolonged speaking. She logs voice quality daily, confirming persistence beyond 21 days.

Step 2 – Symptom checklist: She matches all five items in the key symptom cluster (hoarseness, globus, throat clearing, dry cough, no fever). This meets the clinical threshold for chronic laryngitis.

Step 3 – Examination: Flexible nasolaryngoscopy shows bilateral diffuse edema and erythema with intact mobility, no discrete lesion. Stroboscopy confirms reduced mucosal wave. The findings align with the diagnostic criteria table.

Step 4 – Differential exclusion: No nodules, polyps, or suspicious masses are seen. Reflux symptoms are mild; a short PPI trial is offered but not required for diagnosis. The clinician documents chronic laryngitis secondary to voice overuse with possible reflux contribution.

Step 5 – Management plan: Voice hygiene education, scheduled vocal rest periods, humidified air, and a referral to a speech‑language pathologist for resonant voice therapy. Follow‑up in six weeks to reassess laryngeal appearance and voice outcomes.

Frequently asked questions

How long must hoarseness persist before it is considered chronic laryngitis?
Hoarseness lasting more than three weeks meets the duration criterion for chronic laryngitis.
Can chronic laryngitis be diagnosed without a scope?
A definitive diagnosis usually requires laryngoscopy to visualize diffuse vocal‑fold changes and exclude focal lesions.
What distinguishes chronic laryngitis from vocal‑fold nodules?
Nodules appear as symmetric, localized swellings at the junction of the anterior and middle third of the folds, whereas chronic laryngitis shows diffuse edema and erythema across the entire membranous portion.
Is reflux always the cause of chronic laryngitis?
Reflux can contribute but is not the sole cause; voice overuse, environmental irritants, and chronic cough are also common etiologies.
