Abstract

Background: Otitis media with effusion (OME) is one of the most frequently met pathologies in small children. Long-term persistence of the liquid in the middle ear cavity correlates with the impairment in speech acquisition and poor results in school.

Aim: To evaluate the predictive value of impedancemetry in recovery of the normal middle ear status.

Methods: 30 children (age 4 month-9 years) with OME were periodically monitored by means of tympanometry. The children were treated with the same treatment protocol for 7 days minimum and tympanometry was repeated after seven and fourteen days. After follow-up tympanometry at 7 days, children with abnormal middle ear condition were randomly allocated into two groups: one, which continued the same treatment for another 7 days and one group with no treatment for the next 7 days.

Results: After 7 days, 64% of the patients had an improvement in tympanometry (type C tympanogram) and 10% had a complete resolution of the middle ear effusion (type A tympanogram). After 14 days, tympanometry was normal in 74% of the patients (53.9% rate of success in the no-treatment group).

Conclusion: Complete resolution of the middle ear effusion is obtained in various periods of time, depending on numerous factors, with an appropriate treatment. Tympanometry proved to be a good tool in predicting the length of the treatment.

Keywords: otitis media with effusion; tympanometry.
