BACKGROUND Eustachian tube (ET) dysfunction can be very difficult to diagnose accurately. Our aim is to determine whether a newly developed sonotubometric test using clicks can reliably detect ET opening during swallowing in normal ET subjects, and patulous ET (PET) in subjects with ET dysfunction. METHODS Sixteen subjects (19 normal ET ears and 6 PET ears) were individually placed in a sound...

background and aim: some risk factors for obstructive sleep apnea (osa) such as upper respiratory airways abnormalities and obesity overlap with the risk factors for eustachian tube dysfunction (etd). in this study, we investigated the prevalence of etd in a population of patients with osa. methods: tubal dysfunction was determined by tympanometry and inflation-deflation test in 36 patients dia...

Eustachian tube dilation (ETD) is a relatively new intervention for the treatment of eustachian dysfunction. Though it previously had no assigned billing code, American Medical Association recently accepted Category I Current Procedural Terminology code application ETD to be effective in January 2021. Reported complications are uncommon and usually minor. Herein, we present rare case massive pn...

SUMMARY We report the CT and MR findings in a patient with malignant peripheral nerve sheath tumor in the parapharyngeal space who had neither a family history nor stigmata of neurofibromatosis. A high-resolution CT scan of the temporal bone revealed bony erosion and widening of both the foramen ovale and the bony portion of the eustachian tube. A temporal bone MR image showed an intensely enha...
