What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study looks at how the shape and angle of the eustachian tube (the small canal connecting the middle ear to the throat) relate to pressure inside the middle ear. Researchers will use CT scans to measure these features in 50 healthy people aged 7 and older. The goal is to better understand normal ear anatomy, which could help explain why some people develop ear infections or hearing problems.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand how eustachian tube anatomy affects ear health, potentially guiding future treatments for ear infections or hearing issues.
What could go wrong
This is a small, early observational study with no intervention, so it cannot directly lead to a treatment. Results may not apply to people with ear disease.
