Adenotonsillectomy vs Watchful Waiting in Young Children with Mild–Moderate OSA: Long-term Findings from the KATE Randomized Trial

The KATE trial (n=60) found no between-group difference in polysomnographic OAHI change after 3 years, though adenotonsillectomy improved disease-specific quality of life. Nearly 42% of watchful-waiting children later underwent surgery, suggesting watchful waiting is reasonable for selected young children with mild OSA and small tonsils but requires close follow-up.
