Patulous tube syndrome
Updates to Article Attributes
Patulous tube syndrome (PTS), or patulous dysfunction of the Eustachian tube,is a form of Eustachian tube dysfunction. Whereas the normal dysfunction of failure of the tube to open normally, in PTS in which the tube remains abnormally open, allowing transmission of nasopharyngeal pressure to the middle ear.
During strong inspiration (i.e 'sniff') transmits negative pressure to the middle ear and tympanic membrane retraction of the tympanic membrane and even acquired cholesteatomas secondary to retraction pockets.
Although commonly idiopathic, PTSpatulous tube syndrome is more frequently seen with:
- weight loss
- previous tonsillectomy
- previous radiotherapy
Radiographic features
On imaging, the diagnosis can be suggested by wide patency of the Eustachian tube, often associated with failure to visualize Ostmann's fat pad (inferolateral the to the eustachianEustachian tube and thought to contribute to tubal occlusion).
