Objectives: To determine the prevalence of obstructive adenotonsillar hypertrophy in children and adolescents with sickle cell anemia; to investigate possible associations between the presence of more than five episodes of tonsillitis in the last 12 months and episodes of painful crises in the same period; and to compare the mean annual hemoglobin level in children and adolescents with and without obstructive adenotonsillar hypertrophy.
Methods: Prospective, observational, cross-sectional study involving 85 children and adolescents with sickle cell anemia. All patients answered a questionnaire and underwent a standard otolaryngology examination, including endoscopic endonasal approach. The diagnosis of obstructive adenotonsillar hypertrophy was made according to the Brodsky scale.
Results: The prevalence of obstructive adenotonsillar hypertrophy was 55.3%. Obstructive adenotonsillar hypertrophy was associated with history of difficulty in eating (76.7 vs. 23.5%, p = 0.003), presence of more than five episodes of tonsillitis in the last 12 months (70.6 vs. 29.4%, p = 0.021), loud snoring (73.0 vs. 27.0%, p = 0.004), and sleep apnea (71.8 vs. 28.2%, p = 0.005). Patients with obstructive adenotonsillar hypertrophy had more episodes of recurrent upper airway tract infection (62.5 vs. 37.5; p = 0.010). The presence of more than five episodes of tonsillitis in the last 12 months was associated with episodes of painful crises (median = 12 vs. 2, p = 0.017). There was no significant difference between mean annual hemoglobin levels of patients with obstructive adenotonsilar hypertrophy vs. nonobstructive adenotonsillar hypertrophy: 7.6 vs. 8.2 g/dL, p = 0.199.
Conclusion: The prevalence of obstructive adenotonsillar hypertrophy was 55.3% in children and adolescents with sickle cell anemia; the presence of more than five episodes of tonsillitis in the last 12 months was associated with episodes of painful crises in the same period; there was no difference in the mean annual hemoglobin value among those with or without obstructive adenotonsillar hypertrophy.
