Corticosteroid Use in Tonsillar Conditions

Clinical Context and Dosing

The American Academy of Otolaryngology recommends intravenous dexamethasone 0.15-1.0 mg/kg (maximum 8-25 mg) for patients with tonsil abscess and airway compromise 1
For acute tonsillitis, dexamethasone 8-10 mg IV/IM as initial dose is recommended for adults, and 0.15-1.0 mg/kg (maximum 8-10 mg) for children 1, 2
A short course of 1-3 days is recommended for acute symptom control 3

The European Respiratory Journal recommends intranasal steroids for childhood obstructive sleep apnea in the presence of co-existing rhinitis and/or upper airway obstruction due to adenotonsillar hypertrophy (Grade B recommendation) 5
Intranasal corticosteroids can reduce adenoid size but have inconsistent effects on palatine tonsils, with significant improvements in apnea-hypopnea index (mean pre-treatment AHI 3.7-11 versus post-treatment 0.3-6) 4, 5

The American Academy of Otolaryngology-Head and Neck Surgery strongly recommends a single intraoperative dose of intravenous dexamethasone (0.15 mg/kg) for all children undergoing tonsillectomy 3
Higher doses (0.5 mg/kg) should be avoided due to increased bleeding risk 3

The risk of harm from steroid therapy of 24 hours or less is negligible, with no differences in adverse events reported between corticosteroid and placebo groups 1, 2
Steroid-pulse therapy transiently destroys the discriminative histological structure of tonsils, but this effect is transient and gradually reverses as oral prednisolone is tapered 1, 2
