Diagnosis and Management of Chronic Tonsillitis

Diagnostic Criteria

• The American Academy of Otolaryngology-Head and Neck Surgery recommends that chronic tonsillitis be diagnosed when there are recurrent episodes of tonsillar inflammation, generally with a frequency of ≥7 episodes in the last year, ≥5 episodes per year in the last 2 years, or ≥3 episodes per year in the last 3 years 3

Clinical Evaluation

• Characteristic symptoms of bacterial tonsillitis include fever >38°C 4, tonsillar exudates 2, anterior cervical lymphadenopathy 2, and absence of cough 2, 4
• The presence of non-specific or mild symptoms suggests a viral etiology 2

Diagnostic Tests

• Rapid antigen detection tests (RADT) and/or throat culture are recommended to confirm the presence of Group A Streptococcus (GAS) before initiating antibiotics 1, 4

Modifying Factors to Consider

• Factors that may favor surgical intervention, such as allergy/intolerance to multiple antibiotics, PFAPA syndrome, and history of >1 peritonsillar abscess, should be evaluated 5

Differential Diagnosis

• It is essential to distinguish between chronic GAS carrier with intercurrent viral infections 2, true recurrent bacterial infections, and other causes of chronic sore throat 2

Common Errors to Avoid

• Initiating antibiotic therapy without confirming GAS infection through diagnostic tests 2, 4
• Confusing the state of GAS carrier with recurrent bacterial infections 2
• Indicating tonsillectomy without meeting established criteria for episode frequency 6, 7

Considerations for Surgical Referral

• Watchful waiting is strongly recommended if there have been <7 episodes in the last year, <5 episodes per year in the last 2 years, or <3 episodes per year in the last 3 years 3
• Tonsillectomy is not recommended solely to reduce the frequency of GAS pharyngitis without meeting established criteria 6, 7
