Efficacy of endoscopic powered intracapsular tonsillectomy and adenoidectomy for pediatric obstructive sleep apnea: A retrospective case-control study

Published:September 06, 2022DOI:



      Safe surgery for pediatric patients with obstructive sleep apnea (OSA) is important to decrease postoperative events and improve cost-effectiveness. Therefore, this study aimed to compare surgical efficacy and safety between powered intracapsular tonsillectomy and adenoidectomy (PITA) and extracapsular tonsillectomy and adenoidectomy for OSA in children.


      In this retrospective case-control study, patient characteristics and postoperative outcomes were compared between 93 children with OSA who underwent PITA and 81 children who underwent conventional extracapsular tonsillectomy and adenoidectomy at a tertiary hospital. Data analysis using multivariate, multiple regression, and binomial logistic regression analyses was performed.


      PITA reduced the odds of postoperative hemorrhage by 8.95% (odds ratio [OR]: 5.69, p = 0.013) and of secondary hemorrhage by 8.8% (OR: 10.08, p = 0.006), decreased postoperative analgesia use by 0.35% (p < 0.001), and increased oral intake on postoperative day 1 by 17% (p < 0.001). There were no significant differences in early hemorrhage or regrowth rates between the groups.


      PITA could reduce the risk of secondary hemorrhage and improve postoperative quality of life, which are ideal clinical benefits of surgery in pediatric patients with OSA.
