Understanding Tonsillitis

Tonsillitis occurs when the tonsils become infected and inflamed. The tonsils are part of the lymphatic system and serve as the body's first line of defense against bacteria and viruses entering through the mouth or nose. When overwhelmed by pathogens, they can become infected themselves, leading to the characteristic symptoms of tonsillitis.

The condition can be acute (sudden onset, short duration), recurrent (multiple episodes per year), or chronic (persistent symptoms lasting weeks to months). While tonsillitis can occur at any age, it's most common in school-aged children due to their close contact with other children and developing immune systems.

Understanding the type and cause of tonsillitis is crucial for appropriate treatment. Viral tonsillitis, the most common form, typically resolves on its own with supportive care. Bacterial tonsillitis, often caused by Group A Streptococcus (strep throat), requires antibiotic treatment to prevent complications and reduce contagiousness.

Symptoms of Tonsillitis

The symptoms of tonsillitis can vary in severity and may differ between viral and bacterial infections. Recognition of these symptoms is important for timely treatment and preventing complications.

Primary Symptoms

Associated Symptoms

Severe Symptoms

⚠️ Seek Immediate Medical Care If:

  • Difficulty breathing or swallowing
  • Drooling or inability to swallow saliva
  • High fever (>103°F/39.4°C) or fever lasting >48 hours
  • Severe neck stiffness or swelling
  • Signs of dehydration
  • Muffled or "hot potato" voice

Causes and Risk Factors

Tonsillitis is caused by various infectious agents, with viruses being the most common culprits. Understanding the cause helps determine the appropriate treatment approach.

Viral Causes (70% of cases)

  • Adenovirus: Most common viral cause, also causes cold symptoms.
  • Influenza virus: Causes flu-like symptoms along with tonsillitis.
  • Epstein-Barr virus (EBV): Causes infectious mononucleosis ("mono").
  • Respiratory syncytial virus (RSV): Common in young children.
  • Coronavirus: Including common cold coronaviruses.

Bacterial Causes (30% of cases)

  • Group A Streptococcus (GAS): Causes strep throat, most common bacterial cause.
  • Group C and G Streptococci: Less common but similar presentation.
  • Fusobacterium necrophorum: Can cause severe complications.
  • Corynebacterium diphtheriae: Rare in vaccinated populations.

Risk Factors

Age-Related Factors

  • School-age children (5-15 years)
  • Daycare attendance
  • Immature immune system
  • Close contact with peers

Environmental Factors

  • Crowded living conditions
  • Poor air quality
  • Seasonal changes (winter/spring)
  • Exposure to cigarette smoke

Individual Factors

  • Weakened immune system
  • Chronic allergies
  • Frequent upper respiratory infections
  • Large tonsils naturally

Types of Tonsillitis

Tonsillitis is classified into different types based on frequency, duration, and severity of symptoms. This classification helps determine the most appropriate treatment approach.

Acute Tonsillitis

The most common form, characterized by sudden onset of symptoms lasting less than 10 days. Usually responds well to treatment and may not recur.

  • Sudden severe sore throat
  • High fever
  • Resolves within 3-4 days with treatment
  • Can be viral or bacterial

Recurrent Tonsillitis

Multiple episodes of acute tonsillitis in a year. Defined by specific criteria that may indicate need for tonsillectomy.

  • 7+ episodes in one year
  • 5+ episodes per year for two years
  • 3+ episodes per year for three years
  • May impact quality of life significantly

Chronic Tonsillitis

Persistent inflammation lasting weeks to months, often with less severe but continuous symptoms.

  • Persistent sore throat
  • Bad breath (halitosis)
  • Tonsil stones (tonsilloliths)
  • Chronic tender lymph nodes

Diagnosis

Accurate diagnosis of tonsillitis involves clinical examination and sometimes laboratory tests to determine whether the infection is viral or bacterial, which guides treatment decisions.

Physical Examination

Healthcare providers will examine:

  • Throat and tonsils for redness, swelling, and exudate
  • Neck for swollen lymph nodes
  • Ears for signs of infection or inflammation
  • Skin for rashes (scarlet fever with strep)
  • General vital signs including temperature

Diagnostic Tests

Rapid Strep Test

Quick test (5-10 minutes) to detect Group A Streptococcus:

  • 95% specific but only 70-90% sensitive
  • Negative results may need culture confirmation
  • Positive results indicate bacterial infection

Throat Culture

Gold standard for bacterial identification:

  • Takes 24-48 hours for results
  • More accurate than rapid test
  • Can identify other bacterial causes

Additional Tests

  • Complete blood count (CBC): To assess infection severity
  • Monospot test: If mononucleosis suspected
  • Imaging: Rarely needed unless complications suspected

Clinical Scoring Systems

Centor Criteria for Strep Throat:

  • Fever >100.4°F (38°C)
  • Tonsillar exudate
  • Tender anterior cervical lymph nodes
  • Absence of cough

Higher scores suggest bacterial infection requiring antibiotics.

Treatment Options

Treatment for tonsillitis depends on the cause, severity, and frequency of infections. The goal is to relieve symptoms, eliminate infection, and prevent complications.

Conservative Management

For Viral Tonsillitis:

  • Rest and adequate sleep
  • Increased fluid intake
  • Pain relievers (acetaminophen or ibuprofen)
  • Throat lozenges or sprays
  • Warm salt water gargles
  • Humidified air
  • Avoid irritants like smoke

Medical Treatment

Antibiotics (Bacterial Only)

  • Penicillin V: First-line for strep throat
  • Amoxicillin: Alternative with better taste
  • Azithromycin: For penicillin allergy
  • Cephalexin: Alternative option
  • Complete full course (usually 10 days)

Symptom Management

  • NSAIDs: Reduce pain and inflammation
  • Corticosteroids: For severe cases
  • Topical anesthetics: Throat sprays
  • Antihistamines: If allergies present

Surgical Treatment - Tonsillectomy

Indications for Surgery:

  • Recurrent tonsillitis meeting criteria
  • Chronic tonsillitis unresponsive to treatment
  • Peritonsillar abscess
  • Sleep-disordered breathing
  • Suspected malignancy

Surgical Techniques:

  • Cold knife dissection: Traditional method
  • Electrocautery: Uses heat to remove tonsils
  • Coblation: Radiofrequency ablation
  • Laser tonsillectomy: Precise removal
  • Intracapsular tonsillectomy: Partial removal

Important Treatment Notes:

  • Never give aspirin to children (Reye's syndrome risk)
  • Complete antibiotic course even if symptoms improve
  • Return to school/work 24 hours after starting antibiotics
  • Surgery decision should consider risks vs benefits

Home Care and Recovery

Proper home care is essential for recovery from tonsillitis and can significantly reduce discomfort while supporting the healing process.

Comfort Measures

Hydration and Nutrition

  • Drink plenty of warm or cool fluids
  • Avoid acidic or spicy foods
  • Soft foods: soup, yogurt, smoothies
