What is Laryngitis?
Laryngitis is swelling and irritation (inflammation) of the voice box (larynx) that is usually associated with hoarseness or loss of voice.
What are the symptoms of Laryngitis?
- Fever
- Hoarseness
- Swollen lymph nodes or glands in the neck
What causes Laryngitis?
The voice box (larynx) is located at the top of the airway to the lungs (trachea). The larynx contains the vocal cords. When the vocal cords become inflamed or infected, they swell. This can cause hoarseness, and may sometimes block the airway.
The most common form of laryngitis is an infection caused by a virus. It may also be caused by:
- Allergies
- Bacterial infection
- Bronchitis
- Common cold
- Flu
- Injury
- Irritants and chemicals
- Pneumonia
Laryngitis often occurs with an upper respiratory infection.
Several forms of laryngitis occur in children that can lead to dangerous or fatal respiratory blockage. These forms include:
Who is at risk for Laryngitis?
How do I know I have Laryngitis?
A physical examination can determine whether hoarseness is caused by a respiratory tract infection.
Patients with lasting hoarseness (especially smokers) will need to see an ear, nose, and throat doctor (otolaryngologist) for tests of the throat and upper airway.
