title: Immediate and Sustained Improvement in Behavior and Life Quality by Adenotonsillectomy in Children With Sleep-Disordered Breathing.
abstract: OBJECTIVE
  To investigate longitudinal changes in behavior and quality-of-life (QoL) in children with sleep disordered breathing (SDB) after adenotonsillectomy (AT).
  
  
  METHODS
  This study prospectively enrolled 148 children who underwent AT for SDB. Caregivers filled out Korean attention deficit hyperactivity disorder (ADHD) rating scale (K-ARS) and Korean version of the obstructive sleep apnea-18 (KOSA-18) at preoperative 1 day, postoperative 1 month, and postoperative 6 months. Longitudinal changes in K-ARS and KOSA-18 were evaluated and compared among subgroups.
  
  
  RESULTS
  Both K-ARS and KOSA-18 scores improved immediately at postoperative 1 month and were maintained at postoperative 6 months. The mean preoperative K-ARS scores of the non-ADHD, ADHD-trait, and overt-ADHD groups showed uniformly immediate and sustained improvements. Also, the mean preoperative KOSA-18 scores of the small, moderate, and large impact groups were significantly improved both at postoperative 1 month and 6 months. The changes in behavior and QoL showed no significant differences with regard to the aforementioned factors.
  
  
  CONCLUSIONS
  After AT, we may expect immediate and sustained improvements in behavior and QoL in children with SDB regardless of preoperative symptom severity. Moreover, by performing AT, improvements in behavior and QoL are expected regardless of sex, age, allergic trait, or concurrent coblation-assisted turbinoplasty. These findings may help our colleague physicians counselling pediatric SDB patients and their caregivers.
