[The differences of myringoplasty performed in active and inactive nflammatory stage].

Objective: Through comparing of simple underlay myringoplasty performed in active and inactive inflammatory stage of the chronic otitis media, to explore how the tympanic cavity inflammation affect the outcome of the myringoplasty. Method： Forty-six ears were enrolled in active inflammation group (group A, n =46), and 52 ears were enrolled in inactive inflammation group (group B, n =52). All the patients had received the simple underlay technique myringoplasty. The following-up with otoscope and auditory test had been done in post-operative 12 months. Result: There was no statistic difference of gender and age between two groups. The graft taken-up rate of the group A was 87,0%, that of group B was 90,4%, and there was no statistic difference between two groups( P >0.05).There was no statistic difference of auditory threshold in pre-operative period( P >0.05) and the ABG closure in post-operative period( P >0.05)between two groups. The re-perforation rate of the tympanic membrane also has no difference between two groups( P >0.05). Conclusion： There is no difference of the underlay technique myringoplasty between the active inflammatory stage and inactive inflammatory stage. The active inflammatory condition of the tympanic cavity is not the contraindication of the myringoplasty.
