Laryngitis is an inflammation of the larynx primarily caused by viral infections, voice abuse, or exposure to pollutants. Symptoms include hoarseness, cough, and possible dyspnea, with treatment focused on voice rest, avoiding irritants, and managing underlying infections or allergies. Most patients recover with conservative care, although severe cases may require additional medical interventions.

3. DEFINITION
• an inflammation of the larynx, often
occurs as a result of voice abuse or
exposure to dust, chemicals, smoke,
and other pollutants or as part of a
URI.

5. CAUSES
• The most common cause is a virus, and laryngitis
is often associated with allergic rhinitis or
pharyngitis. (H.Influenza)
• Over use of voice during cold
• Bacterial invasion may be secondary. The onset of
infection may be associated with exposure to
sudden temperature changes,
deficiencies, malnutrition, or
dietary
an
immunosuppressed state.
• Viral laryngitis is common in the winter and is
easily transmitted to others.

6. CLINICAL FEATURES
• hoarseness or aphonia (complete loss of
voice) and severe cough.
• Chronic laryngitis is marked by persistent
hoarseness.
• Other signs of acute laryngitis include
sudden onset made worse by cold dry
wind.
• The throat feels worse in the morning
and improves when the patient is
indoors in a warmer climate.

7. • At times, the patient presents with a dry
cough and a dry, sore
throat that worsens in the evening hours.
• Dyspnea, fever
• If allergies are present the uvula will be
visibly edematous.
• Many patients also complain of a “tickle”
in the throat that is made
worse by cold air or cold liquids.

8. TREATMENT
• Resting the voice
• Avoiding irritants (including
smoking)
• Encourage fluid intake

9. • Inhaling cool steam or an aerosol. If the
laryngitis is part of a more extensive
respiratory infection caused by a bacterial
organism or if it is severe, appropriate
antibacterial therapy
• The majority of patients recover with
conservative treatment
• Eliminating any primary respiratory tract
infection,

10. • Eliminating smoking, and avoiding second hand
smoke.
• Topical corticosteroids, such as
beclomethasone, dipropionate (Vanceril)
may be given by inhalation.
• Treatment for reflux laryngitis typically involves use
of proton pump inhibitors such as omeprazole given
once daily.
