Chronic Tonsillitis - Definition
Chronic tonsillitis is a persistent or recurrent inflammatory condition of the palatine tonsils that results from repeated episodes of acute tonsillitis, leading to progressive structural damage of tonsillar tissue and establishment of a reservoir for infective organisms.
Core Definition (from the textbooks)
"Chronic tonsillitis usually results from repeated attacks of acute tonsillitis in which the tonsils become progressively damaged by inflammatory processes and provide a reservoir for infective organisms."
- Bailey and Love's Short Practice of Surgery, 28th Ed.
Scott-Brown's Otorhinolaryngology (Vol. 2) further refines the distinction:
"Some patients get chronic throat discomfort associated with production of smelly white debris from tonsillar crypts. Occasionally, these debris may become inspissated, calcify and form a tonsillolith. There is no evidence to show a relationship to identifiable tonsillar pathology in these patients."
This contrasts with recurrent tonsillitis, which refers to significant recurring episodes of acute infection. Chronic tonsillitis, strictly defined, refers to the persistent symptom complex rather than repeated discrete acute attacks.
Key Pathological Features
- Repeated bacterial or viral inflammation causes progressive tonsillar tissue damage
- Tonsils develop deep crypts that accumulate food debris, sloughed mucosa, and bacteria (especially anaerobes)
- This creates a persistent reservoir for infection
- Debris within crypts may inspissate, calcify, and form tonsilloliths (tonsillar stones)
- Common organisms include Group A Streptococcus and anaerobes; presence of Actinomyces is a marker of established chronic infection
Clinical Features
- Persistent or chronic sore throat / throat discomfort
- Whitish or yellowish semisolid debris (caseous plugs) on or emanating from the tonsils
- Halitosis (foul taste and odour from the debris)
- Recurrent systemic symptoms (fever, malaise, cervical lymphadenopathy) during exacerbations
- More commonly affects young adults than children
Important Distinction
| Recurrent Tonsillitis | Chronic Tonsillitis | |
|---|---|---|
| Pattern | Discrete episodes of acute infection | Persistent low-grade infection/discomfort |
| Main symptom | Recurring fever, severe sore throat | Chronic halitosis, debris in crypts, low-grade throat discomfort |
| Pathology | Reactive inflammation | Structural crypt damage + persistent bacterial reservoir |
Treatment Considerations
- Frequent gargling (e.g., hydrogen peroxide mouthwash)
- Manual expression of cryptic debris
- Long-term antibiotics (amoxicillin 500 mg TDS x 21 days, or clindamycin 300 mg TDS x 21 days) may help
- Presence of Actinomyces in debris - indicates tonsillectomy is required, as antibiotics are unlikely to be effective
- Tonsillectomy is the definitive treatment; in adults, chronic mouth breathing due to nasal obstruction must be excluded as the underlying cause before surgery
