Evaluating the effect of otoscopic versus microscopic myringoplasty:a Meta analysis / 中国医师进修杂志

ABSTRACT

Objective To evaluate the effect and safety ofotoscopic myringoplasty and microscopic myringoplasty.Methods PubMed,CNKI,VIP database and Wanfang database were searched to identify citations mentioned otoscopic myringoplasty or microscopic myringoplasty.In addition,manual collection of clinical study of related reviews and its references were also conducted.Inclusion criteria of the ordinance made Meta analysis.Results A total of 15 clinical studies with 915 patients (otoscopic group was in 691patients and microscope group was in 224 patients) was identified.According to Q test,there was no heterogeneity between 2 groups (I2 =0),all computed by fixed effects model.Meta analysis demonstrated that there was no significant difference between 2 groups on the type of perforation (OR =1.00,95％ CI0.70-1.42,P =0.13).Both curable rate and enhance of air conduction had no significant difference between 2groups (OR =0.97,95％ CI0.72-1.29,P=0.97;OR =1.14,95％ CI0.68-1.91,P=0.96).The curable rate in otoscopic group was 0.92 (95％ CI0.90-0.94),and the complication rate was 0.030 (95％ CI0.009-0.051).Conclusions The available clinical evidence shows that there is no significant difference between otoscopic myringoplasty and microscopic myringoplasty.However,otoscopic myringoplasty should be recommended to perform in clinical practice because of the feasible and convenient procedure.
