Palatine tonsillitis, often referred to simply as tonsillitis, is inflammation of the palatine tonsils located at the back of the throat. This condition usually occurs when the tonsils become infected by viruses or bacteria. The tonsils are part of the body's immune system and help defend against infections. When pathogens infect the tonsils, they can cause inflammation and the symptoms associated with tonsillitis.

The most common causes of palatine tonsillitis are viral infections, such as the common cold or flu, and bacterial infections, particularly those caused by Streptococcus bacteria. These microorganisms can spread through respiratory droplets, such as when an infected person coughs or sneezes.

What are the Types of Palatine Tonsillitis?

Palatine tonsillitis can be described according to its duration, appearance, and severity. The most common clinical forms include acute and recurrent or chronic tonsillitis.

Acute Tonsillitis: This is a short-term inflammation of the tonsils, usually caused by a viral or bacterial infection. Symptoms may include sore throat, fever, difficulty swallowing, and swollen tonsils.
Chronic or Recurrent Tonsillitis: This occurs when tonsillitis persists or episodes recur frequently. Symptoms may include persistent throat discomfort, bad breath, enlarged tonsils, and repeated infections. In selected cases, tonsillectomy may be recommended.
Follicular Tonsillitis: This term may be used when small pus-filled spots or follicles are visible on the tonsils, commonly in bacterial tonsillitis.
Lacunar Tonsillitis: This describes tonsillitis with white or yellow exudate within the tonsillar crypts and may occur with bacterial or viral infections.
Peritonsillar Abscess: This is a complication rather than a type of tonsillitis. It involves a collection of pus beside the tonsil and may cause severe one-sided throat pain, difficulty swallowing, muffled speech, or difficulty opening the mouth.

What are the Symptoms of Palatine Tonsillitis?

Palatine tonsillitis typically causes symptoms such as a sore throat, difficulty swallowing, swollen and red tonsils, white or yellow patches on the tonsils, fever, ear pain, bad breath, and swollen glands in the neck.

Patients may also experience a scratchy sensation in the throat, headache, and fatigue. If these symptoms persist or become severe, consult a healthcare provider for proper diagnosis and treatment.

Sore throat, often accompanied by pain or discomfort while swallowing
Swollen or enlarged tonsils that may cause a sensation of throat obstruction
Fever, chills, and general feelings of malaise
White or yellow patches on the tonsils, which may occur with bacterial or viral infections
Bad breath, or halitosis, due to inflammation and infection in the throat

What are the Causes of Palatine Tonsillitis?

Palatine tonsillitis is most commonly caused by viral infections, including adenovirus, influenza viruses, and Epstein-Barr virus. Bacterial infections, particularly those caused by Streptococcus pyogenes, can also cause tonsillitis.

These pathogens can spread through respiratory droplets, saliva, or close contact with an infected person. Factors such as frequent exposure to infections, close contact with others, and poor hand hygiene can increase the likelihood of infection.

Practicing good hand hygiene, avoiding close contact with people who are sick, and not sharing utensils or personal items can help reduce the risk of infection.

When to See a Doctor?

Consult an ENT specialist (otolaryngologist) or a primary care doctor if throat symptoms persist, recur frequently, or interfere with eating, drinking, or daily activities. Children with recurrent tonsillitis may also be evaluated by a pediatrician or pediatric ENT specialist.

Severe sore throat or difficulty swallowing
Fever with swollen, red tonsils or white patches
Persistent bad breath or swollen neck glands
Repeated episodes of tonsillitis

Get medical help immediately if:

Difficulty breathing or severe throat swelling
Inability to swallow fluids, excessive drooling, or dehydration
Severe one-sided throat pain, muffled voice, or difficulty opening the mouth
High fever with rapidly worsening throat pain or swelling

These symptoms may indicate a serious complication, such as a peritonsillar abscess or another significant throat infection, requiring urgent medical assessment.

How Is Palatine Tonsillitis Diagnosed?

A healthcare provider diagnoses palatine tonsillitis by reviewing symptoms and examining the throat, tonsils, and neck. The doctor may look for swollen or red tonsils, white patches, fever, and enlarged lymph nodes.

A rapid strep test or throat culture may be performed when a bacterial infection such as group A streptococcal infection is suspected. Blood tests are sometimes used when conditions such as infectious mononucleosis are being considered.

Imaging studies, such as a CT scan, are not routinely required for uncomplicated tonsillitis but may be considered when a complication, such as a peritonsillar abscess or another deep neck infection, is suspected.

What are the Treatment Options for Palatine Tonsillitis?

Treatment for palatine tonsillitis depends on whether the infection is viral or bacterial and how severe the symptoms are. Most viral cases improve with supportive care, while confirmed or strongly suspected bacterial tonsillitis may require antibiotics prescribed by a healthcare provider.

Common supportive measures include adequate fluids, rest, warm salt-water gargles, and pain-relieving or fever-reducing medicines when appropriate. Antibiotics should not be used for viral tonsillitis because they do not treat viral infections.

In cases of recurrent or severe tonsillitis, complications, or significant obstruction, an ENT specialist may consider surgical removal of the tonsils, known as tonsillectomy.

What are the Risk Factors of Palatine Tonsillitis?

Palatine tonsillitis can affect people of all ages but is particularly common in children and adolescents. Risk factors include frequent exposure to respiratory infections, close contact with infected individuals, smoking or exposure to secondhand smoke, allergies, and recurrent throat infections.

Age: Children and adolescents are more likely to develop tonsillitis because of frequent exposure to respiratory infections.
Close Contact: Exposure to people with viral or bacterial infections increases the likelihood of contracting tonsillitis.
Smoking: Tobacco smoke can irritate the throat and tonsils and may increase susceptibility to respiratory infections.
Seasonal Factors: Respiratory infections that can cause tonsillitis are more common during certain seasons.
Recurrent Throat Infections: A history of repeated throat infections can increase the likelihood of recurrent tonsillitis.
