We reevaluated 13 children with primary snoring 3 years after their original polysomnograms were performed and compared them with healthy control subjects. As a group, the patients' snoring and polysomnographic findings did not change. There was no difference in any sleep-disordered breathing of the patients and control subjects. Only the youngest individual in the study developed frank obstructive sleep apnea. Children with primary snoring are not likely to develop polysomnography-confirmed obstructive sleep apnea, and it is safe to defer treatment.
