Speech Videofluoroscopy (Speech X-Ray) - What it is

My Speech X-Ray


A Speech Videofluoroscopy is a moving X-ray that lets us see how well the muscles in a patient’s mouth and throat move when the patient talks.

What is the purpose of a Speech Videofluoroscopy?
A Speech Videofluoroscopy is a moving X-ray that lets us see how well the muscles in a patient’s mouth and throat move when the patient talks.

For patients who have had surgery to correct the position of the soft palate or throat muscles, this procedure may be repeated one year after the surgery. This allows the Surgeon and ST to check how successful the surgery was.

What will happen during a Speech Videofluoroscopy?
A Radiographer and ST will carry out the procedure. A small amount of barium sulphate suspension (white liquid) will be put into the patient’s nose to outline the soft palate and throat muscles on the X-Ray images.

Patients will be asked to stand in front of, and lie down on the couch of an X-Ray (Fluoroscopic) machine. Patients will need to keep very still and will be asked to count and repeat some words after the ST (e.g., See if you can spot the spider).

The fluoroscopy will be recorded in three views. This allows the soft palate and throat muscles to be seen from different angles.

How long does the procedure take?
The fluoroscopy, taken intermittently, should take approximately 5 to 10 minutes. The appointment may last about 30 to 45 minutes to allow setting up for different views/angles.

What happens next?
When the procedure is over, the ST will review the fluoroscopy recording with the patient and their family. Patients may be referred for a speech nasendoscopy (a scope with a camera) that gives a different view of how the soft palate and throat muscles move during speech. An appointment will be made for the patient to see the Plastic Surgeon to discuss the results and treatment suggestions that may be required.

Are there any risks or side effects?

  • Very rarely, some patients may have allergic reactions to the barium sulphate (e.g., trouble breathing, swelling, hives). Patients with a known history of allergy to barium sulphate should tell the ST before the procedure.
  • While there will be exposure to radiation, exposure is minimal. Caregivers accompanying patients will be given a lead apron to wear for protection. Pregnant women and other children are not allowed into the X-Ray room.
  • There may be a slight discolouration of stools due to barium leaving the patient’s body.
  • In rare situations, aspiration of barium sulphate may occur.
