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

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
