Acute Tonsillitis: inflammation of the tonsils

  • Presenting Symptoms: Erythematous (possibly exudative) tonsils, odynophagia, trismus, earache, fever, coughing, headache, halitosis

  • Epidemiology: Tonsillitis can affect people of all ages, but most commonly ages 5-15. 

  • Etiology/Pathophysiology: Viral infection accounts for 70% of tonsillitis cases and often leads to subsequent bacterial superinfection.

    • Most common viral causes: Rhinovirus, Adenovirus, Coronavirus, Epstein-Barr Virus

    • Most common bacterial causes: Group A Streptococcus, Moraxella, H. influenza 

  • Diagnosis:

    • Physical exam (direct visualization of the oral cavity/oropharynx)

    • Rapid Strep, Antistreptolysin-O, bacterial culture, or Monospot tests to determine bacterial/viral etiology

  • Treatment: 

    • Tonsillitis with suspected or confirmed bacterial etiology can be treated with oral antibiotics targeting specific antigen, such as penicillin or clindamycin. 

    • For viral tonsillitis (e.g. EBV), rest, hydration, over-the-counter pain relievers, and throat lozenges are recommended.

    • If a patient is experiencing chronic or recurrent tonsillitis, a tonsillectomy should be considered. 

    • Major indications for tonsillectomy (recurrent or chronic tonsillitis) are defined by the Paradise criteria

  • Paradise criteria:

    • 7 infections in 1 year, 5 infections/year in 2 years, 3 infections/year in 3 years

    • Infection = sore throat with 1 + of following: 

      • >38.3C

      • Cervical adenopathy

      • Tonsillar exudate

      • Positive strep-testing

    • Recurrent tonsillitis not meeting above criteria with antibiotic allergy, PFAPA, or previous peritonsillar abscess
