Laryngeal Pseudomyxoma — Smoker's Hoarseness

What is laryngeal pseudomyxomatosis?

Laryngeal pseudomyxomatosis, or Reinke's edema, is a chronic condition characterized by the accumulation of gelatinous material in Reinke's space — the superficial submucosal layer of the vocal cords. The result: the vocal cords become edematous, heavy, vibrating at a lower frequency. The voice becomes deep, hoarse and "gravelly". In women, the effect is dramatic: the voice becomes significantly masculinized.

Causes

Smoking — the main factor

Present in over 90% of patients. Irritating substances in cigarette smoke cause chronic inflammation with accumulation of gelatinous transudate. The heavier the smoking, the more pronounced the edema.

Other factors

• Laryngopharyngeal reflux — gastric acid worsens the inflammation
• Chronic vocal overuse
• Hypothyroidism — thyroid myxedema can produce similar edema
• Occupational exposure — dust, irritating chemical substances

Symptoms

• Deep, thick voice — progressive lowering of vocal frequency. In women, the voice can drop by one octave
• Chronic hoarseness — loss of vocal clarity
• Fluctuating dysphonia — worse in the morning, slightly improving throughout the day
• Vocal fatigue
• Dyspnea — in advanced cases, edematous vocal cords can partially obstruct the glottis
• Psychological impact — voice masculinization in women causes significant social discomfort

Diagnosis

Videolaryngoscopy shows edematous, translucent vocal cords with bilateral polypoid appearance. Stroboscopy reveals vibration with increased amplitude and reduced frequency.

Important differential diagnosis: hypothyroid myxedema, polyps, laryngeal amyloidosis and superficial forms of glottic carcinoma. Any chronic dysphonia in smokers requires ENT evaluation to rule out laryngeal cancer.

Treatment

Essential measures

• Smoking cessation — an absolutely necessary condition. Without quitting smoking, any treatment is ineffective.
• Reflux treatment — if present
• Vocal hygiene

Laryngeal microsurgery

Indicated when edema does not resolve with smoking cessation. The procedure: bilateral cordal decortication — mucosal incision, aspiration of the gelatinous material, re-draping. Both vocal cords can be operated in separate sessions (4-6 weeks apart). Postoperatively: strict vocal rest for 7-10 days, followed by speech therapy.

Results

Surgery combined with smoking cessation provides good to excellent results. Full recovery: 2-3 months.

An important message about smoking

Laryngeal pseudomyxomatosis is one of the visible manifestations of the effect of smoking on the respiratory system. If the voice has changed — it is a sign that the larynx is suffering. This diagnosis can be a turning point for quitting smoking.
