Tonsillectomy Indications: When to Recommend Surgical Intervention

Tonsillectomy is primarily recommended for children with documented recurrent throat infections meeting the Paradise criteria (≥7 episodes in the past year, ≥5 episodes per year for 2 years, or ≥3 episodes per year for 3 years) or for children with obstructive sleep apnea documented by polysomnography. 1, 2

Recurrent Throat Infections

Primary Indications

  • Tonsillectomy may be recommended when the following Paradise criteria are met:
    • At least 7 episodes of throat infection in the past year, OR
    • At least 5 episodes per year for 2 years, OR
    • At least 3 episodes per year for 3 years 1, 2

Documentation Requirements

  • Each episode must be documented in the medical record with at least one of the following:
    • Temperature ≥38.3°C (101°F)
    • Cervical adenopathy
    • Tonsillar exudate
    • Positive test for group A beta-hemolytic streptococcus 1, 2

Modifying Factors

  • Even if Paradise criteria are not met, tonsillectomy may be considered with these modifying factors:
    • Multiple antibiotic allergies/intolerance
    • PFAPA syndrome (periodic fever, aphthous stomatitis, pharyngitis, and adenitis)
    • History of >1 peritonsillar abscess 1

Watchful Waiting

  • Strong recommendation for watchful waiting if criteria are not met (<7 episodes in past year, <5 episodes per year for 2 years, or <3 episodes per year for 3 years) 1, 2
  • Many cases improve spontaneously over time (untreated children experienced only an average of 1.17 episodes in the first year after observation) 2

Obstructive Sleep-Disordered Breathing

Primary Indications

  • Tonsillectomy is recommended for children with obstructive sleep apnea (OSA) documented by overnight polysomnography 1
  • Presence of tonsillar hypertrophy with symptoms of obstructive sleep-disordered breathing 1, 3

Polysomnography Indications

  • Polysomnography should be performed before tonsillectomy if the child:
    • Is <2 years of age
    • Has obesity
    • Has Down syndrome
    • Has craniofacial abnormalities
    • Has neuromuscular disorders
    • Has sickle cell disease
    • Has mucopolysaccharidoses 1
  • Polysomnography should also be considered when:
    • The need for tonsillectomy is uncertain
    • There is discordance between physical examination and reported severity of symptoms 1

Comorbid Conditions

  • Clinicians should assess for comorbid conditions that may improve after tonsillectomy:
    • Growth retardation
    • Poor school performance
    • Enuresis
    • Asthma
    • Behavioral problems 1

Other Indications

Peritonsillar Abscess

  • Abscess tonsillectomy should be preferred if:
    • Complications have occurred
    • Alternative therapeutic procedures have failed
    • There is bilateral peritonsillar abscess 4
  • Needle aspiration or incision and drainage are preferred if:
    • Comorbidities exist
    • There is increased surgical risk
    • Coagulation disorders are present 4

Infectious Mononucleosis

  • Tonsillectomy is not recommended as a routine procedure for symptom control
  • Only indicated in cases with clinically significant upper airway obstruction resulting from inflammatory tonsillar hyperplasia 4

Special Considerations

Adults with Recurrent Tonsillitis

  • Recent evidence shows tonsillectomy is clinically effective and cost-effective in adults with recurrent acute tonsillitis compared to conservative management 5
  • Adults who underwent tonsillectomy had fewer days of sore throat during 24 months than those with conservative management (median 23 days vs 30 days) 5

Perioperative Management

  • Clinicians should not administer perioperative antibiotics 1
  • A single intraoperative dose of intravenous dexamethasone should be administered 1
  • Ibuprofen, acetaminophen, or both are recommended for post-operative pain control 1
  • Codeine should not be administered to children younger than 12 years 1

Monitoring Requirements

  • Overnight inpatient monitoring is recommended for:
    • Children <3 years old
    • Children with severe OSA (AHI ≥10 obstructive events/hour or oxygen saturation nadir <80%) 1

Common Pitfalls to Avoid

  • Performing tonsillectomy without adequate documentation of recurrent infections 1, 2
  • Failing to consider watchful waiting in cases that don't meet Paradise criteria 1
  • Not obtaining polysomnography in high-risk children with suspected OSA 1
  • Administering perioperative antibiotics, which is strongly recommended against 1
  • Prescribing codeine for post-operative pain in children under 12 1
  • Performing routine interval tonsillectomy after peritonsillar abscess without meeting criteria for elective tonsillectomy 4
