Tonsillitis: A Comprehensive Guide 🦠👄

What Are Tonsils? 🤔

The palatine tonsils are two oval-shaped lymphoid tissue masses located on either side of the back of your throat. Think of them as immune system guards 🛡️ stationed at the entrance to your respiratory and digestive tracts.

What Is Tonsillitis? 🌡️

Tonsillitis is inflammation of the tonsils, usually from infection. It represents approximately 0.4% of outpatient visits in the United States 1.

The Culprits 🦠

• Viral causes (70-95% of cases) 1:

  • 🦠 Epstein-Barr virus (infectious mononucleosis)
  • 🦠 Cytomegalovirus
  • 🦠 Adenovirus
  • 🦠 Common cold viruses

• Bacterial causes (5-30% depending on age) 1:

  • 🔴 Group A β-hemolytic Streptococcus (GAS/Strep pyogenes) - THE most important bacterial cause
  • Accounts for 15-30% in children 5-15 years old
  • Only 5-15% in adults

Clinical Presentation 🤒

What You'll See and Feel:

Symptoms:

• 😣 Severe sore throat (odynophagia)
• 🌡️ Fever (often >38.3°C/101°F)
• 😷 Difficulty swallowing
• 💧 Drooling (especially in children)
• 🗣️ Muffled voice ("hot potato voice")
• 😫 Referred ear pain
• 🤢 Nausea/decreased appetite
• 😴 Fatigue and malaise

Physical Examination Findings:

• 🔴 Red, swollen tonsils (bilateral or unilateral)
• ⚪ White or yellow exudate (pus) on tonsils
• 🔵 Enlarged, tender cervical lymph nodes (neck lumps)
• 🌡️ Fever
• 🔴 Pharyngeal erythema (red throat)
• 😷 Bad breath (halitosis)

Diagnosis 🔬

Step 1: Use a Clinical Scoring System

The Centor Score (or McIsaac modification) helps estimate probability of GAS infection 2, 3:

Criterion	Points
🌡️ Fever >38°C (100.4°F)	+1
⚪ Tonsillar exudate	+1
🔵 Tender anterior cervical lymph nodes	+1
🚫 Absence of cough	+1

Interpretation:

• Score 0-1: 1-5% chance of GAS → ❌ No testing or antibiotics needed
• Score 2: 10-15% chance → Consider testing
• Score ≥3: 40-60% chance → 🧪 Perform rapid strep test or throat culture 3

Step 2: Laboratory Testing (When Indicated)

✅ DO perform:

• Rapid Antigen Detection Test (RADT) for GAS - results in minutes
• Throat culture if RADT negative but high clinical suspicion
• These are the ONLY tests needed for acute tonsillitis 3

❌ DO NOT perform routinely:

• Complete blood count (CBC)
• C-reactive protein (CRP) - though commonly done, not recommended 3
• Antistreptolysin O (ASO) titers - NO value in acute infection 3
• ECG or urine tests
• Repeat throat swabs after treatment 3

Treatment 💊

For Viral Tonsillitis (Most Cases):

Supportive care only:

• 💊 Acetaminophen (paracetamol) for pain/fever
• 💊 Ibuprofen for pain/fever
• 💧 Adequate hydration
• 🍦 Cold foods/drinks for comfort
• 😴 Rest

For Bacterial (GAS) Tonsillitis:

🥇 First-line antibiotic treatment 2:

Penicillin V (oral):

• Children: 250 mg 2-3 times daily
• Adolescents/Adults: 250 mg 4 times daily OR 500 mg twice daily
• Duration: 10 days (complete the full course!)

Alternative: Amoxicillin (oral):

• 50 mg/kg once daily (max 1000 mg) OR
• 25 mg/kg twice daily (max 500 mg per dose)
• Duration: 10 days

For penicillin allergy 🚫🥜:

• Cephalexin: 20 mg/kg twice daily × 10 days
• Cefadroxil: 30 mg/kg once daily × 10 days
• Clindamycin: 7 mg/kg three times daily × 10 days
• Azithromycin: 12 mg/kg once daily × 5 days (but resistance is increasing)

⚠️ CRITICAL WARNING: Never use codeine in children <12 years after tonsillectomy 4

Complications ⚠️

Why Treating GAS Matters:

Suppurative (pus-forming) complications:

• 🔴 Peritonsillar abscess (quinsy)
• 🔴 Retropharyngeal abscess
• 🔴 Cervical lymphadenitis
• 🔴 Mastoiditis

Non-suppurative complications:

• ❤️ Acute rheumatic fever (can damage heart valves)
• 🫘 Post-streptococcal glomerulonephritis (kidney inflammation)
• 🔴 Scarlet fever

Recurrent Tonsillitis & Surgery 🏥

When to Consider Tonsillectomy

The "Paradise Criteria" - tonsillectomy may be recommended if 4:

Frequency requirements (with proper documentation):

• ≥7 episodes in the past year, OR
• ≥5 episodes per year for 2 consecutive years, OR
• ≥3 episodes per year for 3 consecutive years

PLUS each episode must have:

• 🌡️ Temperature >38.3°C (101°F), OR
• 🔵 Cervical lymphadenopathy (tender/enlarged nodes), OR
• ⚪ Tonsillar exudate, OR
• 🧪 Positive GAS test

AND:

• Episodes must be adequately treated with antibiotics
• Episodes must be documented in medical records

Important Considerations About Surgery:

Benefits (modest and temporary) 4:

• ✅ Reduction in throat infections for 1 year only
• ✅ Fewer missed school/work days in first year
• ⚠️ Benefits do NOT extend beyond first year

Risks 4:

• 🩸 Bleeding (primary <24 hours or secondary >24 hours post-op)
• 😫 Significant pain (7-10 days)
• 💧 Dehydration
• 😴 Anesthesia complications
• 🏥 Possible hospitalization
• 💀 Rare but potentially life-threatening complications

⚖️ The reality: Many children with recurrent tonsillitis improve spontaneously over 12 months without surgery 4. Shared decision-making with families is essential given the favorable natural history and modest surgical benefits.

Special Situations 🎯

GAS Carriers 🦠

Some people carry GAS in their throat without being sick. These carriers do NOT need treatment 2 because they:

• Don't spread infection to others
• Are at minimal risk for complications
• Don't benefit from antibiotics

Tonsilloliths (Tonsil Stones) 🪨

• Small white/yellow calcified debris in tonsillar crypts
• Usually asymptomatic
• Managed expectantly (watchful waiting)
• Rarely require surgical intervention 1

Key Takeaways 📝

1. Most tonsillitis is viral - no antibiotics needed! 🚫💊
2. Use Centor score ≥3 to guide GAS testing 🧪
3. Penicillin remains first-line for GAS - 10 days! ⏰
4. Don't order unnecessary tests (ASO, CRP, CBC) ❌
5. Surgery has modest 1-year benefit only - discuss risks/benefits thoroughly ⚖️
6. Document every episode if considering future surgery 📋
7. Never use codeine in children <12 years post-tonsillectomy ⚠️
