Laryngitis

Overview

Laryngitis is inflammation of the larynx (voice box), specifically affecting the vocal cords, which results in hoarseness or complete loss of voice. This common condition occurs when the vocal cords become inflamed, swollen, or irritated, preventing them from vibrating normally. While most cases are acute and resolve within a few weeks, chronic laryngitis lasting more than three weeks requires medical evaluation to identify underlying causes.

The larynx plays a crucial role in breathing, swallowing, and voice production. When inflamed, the vocal cords cannot close properly or vibrate efficiently, leading to the characteristic raspy, weak, or absent voice associated with laryngitis. The condition affects people of all ages but is particularly common in individuals who use their voice professionally, such as teachers, singers, and public speakers.

Understanding the difference between acute and chronic laryngitis is essential for proper management. Acute laryngitis typically results from viral infections or voice strain and resolves with conservative treatment. Chronic laryngitis, however, may indicate more serious underlying conditions such as acid reflux, allergies, chronic sinusitis, smoking-related damage, or rarely, cancer. Early recognition and appropriate treatment can prevent complications and preserve vocal health.

Common Symptoms

Laryngitis symptoms primarily affect the voice and throat, though the severity and combination of symptoms vary depending on the underlying cause and whether the condition is acute or chronic.

Voice Changes

• Hoarseness: Rough, raspy voice quality
• Voice loss (aphonia): Complete inability to produce sound
• Weak voice: Reduced volume and projection
• Voice breaks: Intermittent voice cutting out
• Pitch changes: Higher or lower than normal voice
• Voice fatigue: Tiring quickly when speaking

Throat Symptoms

• Throat pain: Ranging from mild discomfort to severe pain
• Dry throat: Persistent dryness despite hydration
• Tickling sensation: Constant urge to clear throat
• Raw feeling: Burning or scraped sensation
• Difficulty swallowing: Mild discomfort when swallowing
• Globus sensation: Feeling of lump in throat

Associated Symptoms

• Dry cough: Non-productive, irritating cough
• Mild fever: Usually low-grade in viral cases
• Fatigue: General tiredness with infection
• Runny nose: If associated with upper respiratory infection
• Swollen lymph nodes: Tender nodes in neck
• Ear pain: Referred pain from throat

Chronic Laryngitis Symptoms

• Persistent hoarseness: Lasting over 3 weeks
• Morning voice problems: Worse upon waking
• Throat clearing: Frequent need to clear throat
• Excessive phlegm: Mucus in throat
• Voice changes throughout day: Fluctuating symptoms

Types of Laryngitis

Understanding the different types of laryngitis helps determine appropriate treatment and prognosis.

Acute Laryngitis

Most common form, lasting less than 3 weeks:

• Viral laryngitis: Most frequent cause (cold, flu viruses)
• Bacterial laryngitis: Less common, may need antibiotics
• Fungal laryngitis: Rare, in immunocompromised patients
• Traumatic laryngitis: From voice overuse or injury

Chronic Laryngitis

Lasting more than 3 weeks, requires investigation:

• Reflux laryngitis: From acid reflux (LPR)
• Allergic laryngitis: Environmental allergens
• Irritant laryngitis: Smoking, chemicals, pollution
• Mechanical laryngitis: Chronic voice abuse
• Infectious chronic laryngitis: TB, syphilis (rare)

Special Types

• Singer's laryngitis: Professional voice users
• Laryngitis sicca: From extreme dryness
• Hemorrhagic laryngitis: With vocal cord bleeding
• Ulcerative laryngitis: With ulcer formation
• Granulomatous laryngitis: From systemic diseases

Causes

Laryngitis results from various factors that irritate, inflame, or damage the vocal cords. Identifying the cause is crucial for effective treatment.

Infectious Causes

• Viral infections: Common cold, influenza, COVID-19, RSV
• Bacterial infections: Streptococcus, Haemophilus, Moraxella
• Fungal infections: Candida (in immunocompromised)
• Secondary infections: Following viral illness

Non-Infectious Causes
