What Is a Retropharyngeal Abscess?
A retropharyngeal (reh-tro-fah-RIN-jee-ul) abscess is an infection that forms behind the back wall of the throat. They're not common in children, but when they do happen, it is usually in those younger than 5 years old.
What Causes a Retropharyngeal Abscess?
A retropharyngeal abscess happens when bacteria grow in the lymph nodes behind the throat. Lymph nodes help fight infections by removing germs, but sometimes they can’t keep up.
What Are the Signs & Symptoms of a Retropharyngeal Abscess?
At first, a retropharyngeal abscess may cause a sore throat, fever, and tender in the neck.
Without treatment, symptoms can get worse. A child might:
- refuse to eat or drink because swallowing is painful
- have a stiff neck and not want to move it because of pain
- have a swollen neck or glands
- keep their mouth closed tight
- speak in a hoarse or muffled voice
- have trouble breathing or noisy breathing
- have chest pain
How Is a Retropharyngeal Abscess Diagnosed?
A doctor usually can diagnose a retropharyngeal abscess based on symptoms and by examining a child’s mouth, throat, and neck.
If a retropharyngeal abscess seems likely, the child should see an ear, nose, and throat (ENT) specialist. Blood tests, X-rays, or a CT scan can help doctors make the diagnosis.
How Is a Retropharyngeal Abscess Treated?
A child with a retropharyngeal abscess needs treatment in a hospital. Doctors will give IV (into a vein) antibiotics and might need to do surgery to drain the abscess. This is recommended if:
- The child has breathing problems.
- The abscess is very large.
- Symptoms don’t improve after 1 or 2 days on antibiotics.
If a child has breathing problems, doctors will use a breathing tube to keep the airway open before the child has surgery.
Most children can switch to oral antibiotics if their symptoms improve after several days of IV antibiotics.
