Objective To observe the feasibility and advantages of coblation tonsillectomy with inferior pole capsule preservation in pediatric obstructive sleep apnea(OSA)patients.Methods A retrospective study was performed on 91 patients who underwent coblation tonsillectomy with inferior pole capsule preservation(inferior pole capsule preservation group)from August 2018 to December 2019 and 100 patients who received routine coblation tonsillectomy(routine group)from January 2017 to July 2018 for OAS in children.The operation time,intraoperative bleeding,postoperative pain score,postoperative complications and 1-year follow-up results were compared between the two groups.Results There were no statistical differences in the operation time and intraoperative bleeding between the two groups.The pain scores in the inferior pole capsule preservation group on postoperative day 1 and day 3 were lower than those in the routine group(P＜0.05).The postoperative bleeding rate in the routine group(7/100,7% )was higher than that in the inferior pole capsule preservation group(2/91,2.19% )(P＜0.05).During 1-year follow-up,no local infection and recurrent tonsillar hypertrophy were observed in both groups.Conclusion Tonsillectomy with inferior pole capsule preservation is a safe and effective surgical method for children with OSA,which can effectively reduce the risk of postoperative bleeding and postoperative pain.
