Manometric eustachian tube function tests in children with ventilation tubes

In this study, manometric Eustachian tube function tests were performed repeatedly at ten days, one month, three months and nine months after ventilation tubes insertion in 20 children with persistent otitis media effusion [OME]. Opening and closing pressures [passive tubal function] and active tubal function were measured. There was a significant increase in opening pressure. The closing pressure followed a similar pattern but the increase did not reach the statistically significant level. No significant change in tubal function group was found during the follow up sessions and remained in the same poor level. There was a positive significant correlation between opening and closing pressures and ET function grouping in all follow up sessions
