Myringoplasty with double flaps in treatment of large tympanic membrane perforation

Objective To investigate the clinical effect of myringoplasty with double flaps in treatment of large tympanic membrane perforaton.Methods Ninety-five patients (112 ears) with large tympanic membrane perforation were enrolled in this study,48 patients (54 ears) were performed myringoplasty with double flaps (double flaps method group) and 50 patients (58 ears) were performed myringoplasty with underlay method (underlay method group).The air conduction (AC) and air bone gap (ABG) were measured before operation and 6 months after operation.The clinical efficacy of two groups was compared.Results The successful rate in double flaps method group was 96.3％ (52/54) and 91.4％ (53/58) in underlay method group,there was no significant difference (P ＞0.05).The effective rate in double flaps method group was 92.6％ (50/54) and 77.6％ (45/58) in underlay method group,there was significant difference (P ＜ 0.01).Conclusions Myringoplasty with double flaps in treatment of large tympanic membrane perforation can effectively mould tympanic membrane and improve hearing.The operation is worthy of spreading.
