Effect of Plasma-mediated Temperature-controlled Radiofrequency Ablation on Obstructive Sleep Apnea Hypopnea Syndrome in Children / 中国微创外科杂志

ABSTRACT

Objective To evaluate the efficacy of tonsils and adenoid ablation by plasma-mediated temperature-controlled radiofrequency for obstructive sleep apnea hypopnea syndrome (OSAHS) in children. Methods From August 2005 to May 2007,43 cases with OSAHS received tonsillectomy and adenoid radical resection with Evac70 tool bit using a plasma-mediated temperature-controlled system. The clinical data of the patients were reviewed. Results The mean operation time was 16 minutes,ranged from 10 to 20 minutes. During the operation,the patients had a mean of 3 ml hemorrhage (1 to 10 ml). Compared with the preoperative examination,the patients showed significantly lowered AHI [(14.6?4.6) times/h vs (4.2?2.7) times/h,t=8.563,P=0.000] and OAI [(6.9?3.5) times/h vs (3.3?1.4) times/h,t=5.443,P=0.000] and increased minimum blood oxygen saturation [(85.7?4.4)% vs (99.7?0.2)%,t=-6.687,P=0.000]. Conclusions The ablation of the tonsil and adenoid using plasma-mediated temperature-controlled radiofrequency is effective and safe for children with OSAHS.
