Sonotubometry in children with otitis media with effusion before and after insertion of ventilation tubes.

Objectives: To test the outcome of sonotubometric measurement in children with otitis media with effusion (OME) before and after insertion of ventilation tubes.

Design: Eustachian tube ventilatory function was tested in children with OME. To test validity, sonotubometric testing took place before insertion of ventilation tubes (ie, glue ear) and 1 week and 3 months after grommet insertion (ie, aerated middle ear cavity).

Results of sonotubometry in testing eustachian tube ventilatory function in children with cleft palate.

Objectives: In previous studies, an updated sonotubometry setup was tested in healthy adults and children to test its validity and reproducibility in the assessment of the ventilatory function of the eustachian tube (ET). The results were promising, but further investigations were needed to confirm the discriminative potential of this sonotubometry setup. Our objective in the present study was to test the discriminative potential of an updated sonotubometry setup in children with cleft palate.

Sonotubometry: a useful tool to measure intra-individual changes in eustachian tube ventilatory function.

Objective: To determine whether intra-individual changes in eustachian tube (ET) function induced by local application of a histamine phosphate solution can be detected using an improved sonotubometer.

Design: The function of the ET was measured with a revised sonotubometer before and after histamine was applied to the nasopharyngeal ostium of the ET.

Setting: Tertiary referral hospital.

Reproducibility of sonotubometry as Eustachian tube ventilatory function test in healthy children.

Objectives: To devise a simple and reliable diagnostic procedure to test Eustachian tube function routinely in an ENT outpatient setting. One method to measure ET ventilatory function is sonotubometry. The reproducibility of a recently updated sonotubometry set-up was tested in healthy children.

Sonotubometry: eustachian tube ventilatory function test: a state-of-the-art review.

Objective: Disturbance of any of the ET functions may contribute to the development of otitis media. Sonotubometry measures the ventilatory function using sound. The qualities of sonotubometry as a test for eustachian tube ventilatory function have been studied by various investigators.
