Laryngitis:  inflammation of the larynx

Acute laryngitis may occur as an isolated infection or as part of a
generalized bacterial or viral upper respiratory tract infection. 

Cause:  Acute laryngitis results from infection, excessive use
of the voice, inhalation of smoke and or fumes, and aspiration of caustic

and mouth breathing.



Pain – especially when swallowing and or speaking


Dry cough


Laryngeal edema

Chronic laryngitis – A persistent cough


Resting the voice would be the primary treatment.

Analgesics and throat lozenges for pain – for viral infection

Antibiotic therapy – for bacterial infection

May require hospitalization – for severe, acute laryngitis

Occasionally, when laryngeal edema results in airway obstruction, a
tracheotomy (incision of an opening into the trachea through the skin and
the muscles of the neck) may be necessary.

In chronic laryngitis, effective treatment must eliminate the underlying

Suggestion:  Patient should maintain adequate humidification by
using a vaporizer or humidifier during the winter, by avoiding air conditioning
during the summer (because it dehumidifies), by using medicated throat
lozenges, and by not smoking.  Completing the prescribed antibiotic
therapy.  Modification of predisposing habits.
