Eustachian tube: annotated CT

Case contributed by Jeffrey Cheng

Annotated CT of the facial bones which nicely demonstrates the path of the eustachian tube from the middle ear to the nasopharynx

The same CT facial bones without above annotations

Case Discussion

Following the eustachian tube in CT scans can be difficult as it is not always patent along its entire length. However, if the patient were to perform a valsalva manoevre, this space would likely open up and become easily visible.

In this particular scan the patient is not performing such a manoevre, but the path is still visible.
