Tonsillitis is an inflammation or infection of the tonsils.
The body has two sets, or pairs, of tonsils. The palatine tonsils can be seen at the back of the throat. The lingual tonsils are at the back of the tongue and cannot be seen by looking in the mouth. Tonsillitis usually means the inflammation or infection of the palatine tonsils. Sometimes, however, the infection can involve the lingual tonsils and lymph nodes in the back of the throat.
There are three forms of tonsillitis: acute, with rapid onset of significant symptomssubacute, with a slow onset of less obvious symptomschronic, with intermittent symptoms that persist over time
Symptoms of acute tonsillitis include: the rapid onset of severe sore throat that worsens over timemoderate to high feverdifficulty swallowingred, enlarged tonsils that may or may not have pus on the surface or in the pitsswollen or tender lymph nodes below the jaw
Symptoms of subacute tonsillitis can last from 3 weeks to 3 months, and include: somewhat enlarged tonsilsfoul-smelling, pasty, infected material that collects inside the pits on the tonsilsfluctuating mild to moderate sore throatbad breathfoul taste in the mouthmildly swollen, tender lymph nodes
Symptoms of chronic tonsillitis include: enlarged, mildly red tonsils that are scarred with large pitsslightly enlarged lymph nodes that are not usually tendersore throat that comes and goes
Common causes of acute tonsillitis may include: bacteria, such as streptococci or Hemophilus bacteriaviruses such as adenovirus or Epstein-Barr virus, which also causes mononucleosis diphtheria, a serious disease that produces a false membrane in the throat. Diphtheria can be prevented by the DTaP vaccine.
Subacute tonsillitis is most commonly caused by Actinomyces, a normal mouth bacterium that can cause infection. In chronic tonsillitis, there is a long-standing infection that is almost always bacterial.
The best way to prevent acute tonsillitis is to avoid people who have strep throat or any of the bacterial or viral infections that can lead to acute tonsillitis.
A person can get acute tonsillitis by: coming into contact with someone who has strep throat or mononucleosishaving strep throat that develops into tonsillitissharing utensils or toothbrushes with someone carrying strep bacteria or Epstein-Barr virus
There is no way to prevent subacute or chronic tonsillitis.
A healthcare professional can diagnose acute tonsillitis based on the person's health history and a physical exam. A throat culture can help identify the organism causing the infection. A complete blood count (CBC) can also help determine if the infection is caused by a virus or bacteria.
If the individual has infectious mononucleosis, the lymph nodes in the neck, armpit, or groin will be enlarged. An antibody titer may be done to check for antibodies to the Epstein-Barr virus. Rapid in-office tests may also be used to assist in making the diagnosis.
A healthcare professional can diagnose subacute or chronic tonsillitis based on a person's health record and a physical exam.
Usually, no significant long-term effects result from any of the three forms of tonsillitis. However, difficulty swallowing or breathing during sleep can result if the chronic infection causes enlargement of the tonsils. The healthcare professional may recommend a tonsillectomy, or removal of the tonsils, if there are recurrent infections or difficulties with swallowing and breathing.
Streptococcal, diphtheria, and Epstein-Barr infections are all contagious.
Acute tonsillitis is usually treated with: pain medication oral fluidsmedications to lower fever
For acute tonsillitis caused by strep bacteria, antibiotics will usually cure the infection. Unfortunately, some types of streptococcal bacteria are becoming resistant to penicillin. This means higher doses of amoxicillin or a different antibiotic need to be used.
Since antibiotics are not effective against viruses, the only treatment for tonsillitis caused by viral infection is medication to reduce fever and pain. Oral steroids may be given for a short period of time if symptoms are severe. Oral steroids can lessen the symptoms of tonsillitis caused by mononucleosis.
Antibiotics can be helpful in preventing infection if material has collected on the surface of the tonsils. In subacute tonsillitis caused by Actinomyces, penicillin and clindamycin are effective. If these antibiotics do not work, the person can remove the infected material from the tonsil pits with a finger or special irrigating tool. Otherwise, the tonsils should be removed.
In cases of chronic tonsillitis, antibiotics combined with oral steroids may resolve the infection. If not, the tonsils should be removed. Tonsillectomy may be recommended by the healthcare professional if the person has had: 3 to 5 bacterial infections of the tonsils within 3 to 5 yearsmore than 6 episodes of tonsillitis in one yearchronic tonsillitis, or infection of the tonsils, that does not respond to antibioticsenlargement of the tonsils that causes sleep apnea, a breathing disorder that occurs during sleepenlargement of the tonsils that causes difficulty swallowing, especially in children
Side effects depend on the medications used, but may include allergic reactions and upset stomach. Surgery to remove the tonsils can cause bleeding, infection, or reactions to anesthesia.
Most viral episodes of tonsillitis will resolve without further problems. Antibiotics should clear up infections caused by strep or other bacteria. After recovery from tonsillectomy, the person should be free of symptoms.
Any new or worsening symptoms should be reported to the healthcare professional.
