Suspension Laryngoscopy Versus Electronic Laryngoscopy Or Fibrolaryngoscope For Treating Vocal Cord Poloyp:a Mata-Analysis

Objective To evaluate the efficacy of treating vocal cord polyp objectively by suspension laryngoscopy versus electronic laryngoscope or fibrolaryngoscope.Methods Databases as VIP, Wanfang, Cochrane Central Register of Controlled Trials, PubMed, EMbase, CNKI and CBM were searched. After study selection, reviewers conducted the assessment and extracted data independently. And then meta-analyses were performed by using the RevMan 5.1 software.Results Eight studies involving,950 patients were included. The results of meta-analyses showed that:No statistical significance between the two the operations about the total effective rate[RR=1.06,95%CI(0.97,1.15), P=0.20].No statistical significance between the two the operations about the cure rate[RR=1.18,95%CI(0.99,1.41), P=0.07].But the cure rate of treating wide vocal cord polyp by suspension laryngoscopy is higher than through electronic laryngoscope or fibrolaryngoscope [RR=1.51,95%CI(1.27,1.79),P<0.00001].Conclusion The current evidence shows that no statistical significance between the two the operations about the total effective rate and the cure rate. But it’s more effective to treat wide vocal cord polyp by suspension laryngoscopy than electronic laryngoscope or fibrolaryngoscope.
