Abstract：Objective To investigate the effect of adenotonsillectomy or adenoidectomy in the treatment of obstructive sleep apnea syndrome (OSAS) in children with adenoidal hypertrophy. Methods The clinical menifestations and overnight polysomnography findings in 20 children with OSAS secondary to adenoidal hypertrophy (OSAS group) were compared before and after adenotonsillectomy or adenoidectomy and were compared with those in 10 children with adenoidal hypertrophy without OSAS (Control group) admitted to Beijing Children's Hospital at the same period as the OSAS group. Results There was no significant difference in the incidence of the common symptoms between the OSAS group and the Control group. The body mass index, A/n ratio in the neck roentgenography, total sleep time, sleep efficiency, and the proportion of S1, S2 and slow wave sleep (SWS) time and rapid eye movement (REM) time of the OSAS group did not differ from those of the Control group. After adenotonsillectomy or adenoidectomy, the apnea index, apnea hypopnea index of all children with OSAS and obstructive apnea index significantly decreased and the proportion of REM sleep time in the total sleep time significantly increased (P< 0.05 or 0.01 ). Conclusions There are no differences in clinical manifestations, A/n ratio and the sleep architecture between the adenoidal hypertrophy children with and without OSAS. Adenotonsillectomy or adenoidectomy is effective in the treatment of childhood adenoidal hypertrophy with OSAS.
