An 8-year-old girl with a recurrence of obstructive sleep apnea syndrome caused by hypertrophy of tubal tonsils 4 years after adenotonsillectomy.
Obstructive sleep apnea syndrome affects 1% to 2% of children. It is caused mainly by upper airway obstruction and manifests as snoring and sleep disturbance. Adenotonsillectomy can improve quality of life because airway obstruction occurs when both tonsils and adenoids are enlarged. We describe an 8-year-old girl with a recurrence of obstructive sleep apnea syndrome caused by hypertrophy of the tubal tonsils 4 years after adenotonsillectomy. The findings from this case highlight the importance of 1) identifying hypertrophy of the residual adenoid and compensatory hypertrophy of the tubal tonsils in patients with obstructive sleep apnea syndrome after adenotonsillectomy and 2) determining the optimal timing of adenotonsillectomy with respect to both the severity of obstructive sleep apnea and compensatory hypertrophy of other lymphoid tissue of Waldeyer's ring, as growth of such tissues is most active during the first several years of life.
