Treatment for Adenoid Hypertrophy in Pediatrics
Initial Treatment Approach
The initial treatment for pediatric adenoid hypertrophy should be a trial of intranasal corticosteroids for 8-12 weeks before considering surgical intervention. 1, 2
Medical Management (First-Line)
Intranasal Corticosteroids
- Intranasal corticosteroids are the primary medical treatment and should be tried first in all cases without severe obstructive sleep apnea. 1
- Fluticasone propionate nasal drops at 400 mcg/day for 8 weeks can reduce adenoid size by approximately 35% and eliminate the need for surgery in 76% of patients. 3
- The combination of azelastine-fluticasone (137 mcg azelastine + 50 mcg fluticasone) twice daily for 12 weeks is highly effective, removing 96% of patients from surgical waiting lists. 4
- Treatment duration should be 8-12 weeks with documented assessment of response before proceeding to surgery. 2
Alternative Medical Options
- Montelukast 5 mg daily for 12 weeks can reduce adenoid size in 76% of children and significantly improve symptoms (sleep discomfort, snoring, mouth breathing). 5
- This leukotriene receptor antagonist may be considered when intranasal steroids fail or as adjunctive therapy. 5
Indications for Surgical Intervention (Adenoidectomy)
Absolute Indications
Surgery is indicated when medical management fails AND one or more of the following are present:
- Documented obstructive sleep apnea with witnessed apnea episodes AND excessive daytime sleepiness. 1, 2
- Chronic adenoiditis unresponsive to medical therapy after 8-12 weeks. 1, 2
- Recurrent otitis media with effusion lasting ≥4 months with persistent hearing loss. 2
- Structural damage to the tympanic membrane or middle ear. 2
- Significant nasal obstruction with failure of 8-12 week trial of intranasal corticosteroids. 1, 2
Age-Specific Considerations
- For children ≥4 years old: Adenoidectomy is appropriate as standalone procedure or with tympanostomy tubes for otitis media with effusion, reducing future operations by 50%. 6, 2
- For children <4 years old: Tympanostomy tubes alone are preferred for otitis media with effusion, as surgical and anesthetic risks of adenoidectomy outweigh limited benefits in this age group. 6
- For children <2 years old with recurrent acute otitis media: Adenoidectomy is most beneficial when middle ear effusion is present (number needed to treat = 9). 6
Contraindications
- Children with overt or submucous cleft palate should NOT undergo adenoidectomy due to risk of velopharyngeal insufficiency. 6
Clinical Assessment Required Before Surgery
Document the following before proceeding to adenoidectomy:
- Presence or absence of witnessed apnea episodes during sleep. 2
- Excessive daytime sleepiness or behavioral changes. 2
- Impact on growth, school performance, or quality of life. 2
- Response to 8-12 week trial of intranasal corticosteroids. 2
- Hearing status if recurrent ear infections are present. 2
Common Pitfalls to Avoid
- Do not perform adenoidectomy solely for recurrent throat infections - this is an indication for tonsillectomy, not adenoidectomy. 6
- Do not skip the medical management trial - intranasal corticosteroids should be attempted for 8-12 weeks unless severe obstructive sleep apnea is documented. 1, 2
- Do not proceed to surgery based on adenoid size alone - the benefit of adenoidectomy for otitis media is unrelated to adenoid size but relates to bacterial reservoir. 6
- Anesthesia mortality risk is approximately 1:50,000 with hemorrhage risk of approximately 2%. 6
Treatment Algorithm Summary
- Start with intranasal corticosteroids (fluticasone propionate 400 mcg/day or azelastine-fluticasone combination) for 8-12 weeks. 1, 2, 4, 3
- Reassess symptoms and adenoid size at 8-12 weeks. 2
- If improved: Continue medical management and monitor. 1
- If failed medical management OR documented severe OSA: Proceed to adenoidectomy with age-appropriate considerations. 1, 2
- Consider montelukast as alternative or adjunct if steroids contraindicated or partially effective. 5
