RESULT: 15.7%(8/51) ears were cured,the total efficiency rate is 96.1%(49/51). The eustachian tube function had been straightened up in 13.7%(7/51)ears,the other symptoms were improved in different degrees for the cars of setting grommet, 25.5% ears occurred otorrhea, 9.8% ears occurred perforation.

CONCLUSION
