You may have some changes in your voice when you have a sore throat. Usually these changes go away as your sore throat goes away. Laryngitis can often change your voice.
However, a muffled voice may mean that you are developing a more
serious problem, such as
epiglottitis or an
abscess near the
tonsils
(peritonsillar abscess). Epiglottitis is
inflammation of the epiglottis. The epiglottis is a leaf-shaped flap of tissue
over the opening to the large breathing tube leading to the lungs (trachea
). This flap of
tissue closes when a person swallows to prevent food and fluids from getting
into the breathing tubes. Epiglottitis is more common in adults than in
children but may be more serious in children.
When the epiglottis becomes inflamed and swollen, it can rapidly block the breathing tube. Epiglottitis generally begins suddenly, without a previous upper respiratory infection or cough. Symptoms may include:
Most cases of bacterial epiglottitis in children are caused by Haemophilus influenzae. This infection can be prevented with the Haemophilus influenzae type b (Hib) vaccine. In adults, bacterial epiglottitis is usually caused by a strep infection.
A child with epiglottitis appears very sick and in distress. If your child has symptoms of epiglottitis, seek emergency care.
