Efüzyonlu Otitis Media Tanısı Alan Çocukların Takip Sürecinde Muayene Bulgularındaki Değişikliklerin Geniş Bant Timpanometri ile Belirlenmesi

Abstract

Otitis media with effusion (OME) is one of the most common childhood diseases. It is recommended to use tympanometry in addition to otoscopy and/or pneumatic otoscopy for the diagnosis and follow-up of OME. The use of Wide band tympanometry (WBT), which is one of the methods of evaluating the middle ear in the diagnosis of OME, is being more widely used. In this study, the relationship between the changes in the examination findings obtained by otoscopy and pneumatic otoscopy and the findings of WBT in the monthly follow-ups performed during the three-month period of children diagnosed with OME, was examined. In the study, 48 ears of 26 individuals aged 2-5 who were diagnosed with OME were evaluated. Otoscopy, pneumatic otoscopy, 226 Hz tympanometry and WBT measurements were performed at the initial, first, second and third month examinations. It was noticed that the change observed with both otoscopy and pneumatic otoscopy between the initial and first month control could not be adequately determined by 226 Hz tympanometry, but the change in the amount absorbance at 2520 Hz and 3175 Hz in WBT was moderately correlated with the examination findings. However, it was observed that the change between the first and the second follow-up examinations was significant at the frequency range of 226 Hz -630 Hz and the change between the second and third months was significant at the frequency range of 226 Hz-4000 Hz. The findings obtained in the study show that, 226 Hz tympanometry may be insufficient to reflect the change in examination findings while WBT can provide more detailed information to support the examination findings during the follow-up period as well as the diagnosis of OME.
