Objective:To compare the effect of endoscopic-assisted low temperature plasma (ELTP) and electric planer (EP) on the treatment of adenoid hypertrophy.Methods:We searched China National Knowledge Infrastructure (CNKI),Wanfang Database,Weipu Database,Chinese Biomedical Literature (CMB),PubMed,Embase,Cochrane Database,and collected the randomized controlled studies regarding the effect of ELTP and EP on the treatment of adenoid hypertrophy from January 2007 to June 2016.Methodologies were used to evaluate the included studies,and Meta-analysis was performed by Revman 5.2.Results:Thirteen studies including 1 448 patients fulfilled the study requirement.Seven hundred and twenty-two patients were treated with ELTP,and 726 patients were treated with EP.The Meta-analysis showed:compared with EP,ELTP could improve the cure rare (OR=3.19,95％ CI 1.42to 7.15,P=0.005),reduce the blood loss during surgery (MD=-20.35,95％ CI-20.84 to-19.87,P＜0.001),shorten the operation time (MD=-15.71,95％ CI-18.06 to-12.17,P＜0.001),and reduce the incidence of complications (OR=0.13,95％ CI 0.06 to 0.30,P＜0.001),while there was no difference between the 2 groups in the postoperative residual rate of adenoid,postoperative hemorrhage rate and the rate oftorus tubarius injury.Conclusion:Comparing with EP,ELTP shows more advantages in the adenoidectomy.
