The clinic analyse of adhering otitis media / 中国基层医药

ABSTRACT

Objective To assess result with multi-measures operation for adhering otitis media.Methods The operation of 100 cases(110 ears) were used by mauto-bone,absorbable merogel,tympanic chorda nerve as a spring press prostheses etc,and were followed up for example auto-bone cup pole or gung-pole as total and partial ossicular replacement prostheses,scute rebuild.Results 110 ears mean air-bone gap(AB gap) was(38.60?12.70)dB pre-operation.It was(15.28?11.69)dB post-operation.The AB gap closure to with in 20dB as succeed achieved in 70%(77 ears).AB gap closure in 10 dB as best result in 40%(44 ears).Air conduction was under 40dB in 75%(83 ears).AB gap closure not enough 10 dB and air conduction over 40 dB as no effect was 6%(7 ears).Conclusion As long as technique measures is right,even though adhering middle ear has much difficulty in operation,the succeed rate can gain 70%,but still 30% has no satisactory effect,more study is necessary.
