"A Continuous Positive Airway Pressure (CPAP) machine can improve swallow function if you've had a total Laryngectomy."
Age: 18 years or older
Healthy Volunteers: No
Keywords: swallowing, laryngectomy, CPAP, Continuous Positive Airway Pressure, improve swallow function, swallow function, total laryngectomy
Type: Device study
10 Participants
This research will determine whether the use of Continuous Positive Airway Pressure (CPAP) can improve swallowing in patients who underwent total laryngectomy and are experiencing difficulty swallowing. Total laryngectomy removes the larynx and separation of the airway from the mouth, nose and esophagus. In normal individuals, CPAP machine delivers enough air pressure to keep upper airway passages open. Since your airway is separated from your mouth and esophagus, the mask will apply pressure on your mouth and esophagus during swallowing.
This study requires

If you agree to take part in this study, during standard video fluoroscopic study, you will swallow barium-coated foods of different volumes and consistencies. Barium will allow the food to show better on X-rays.

Your doctor can then see changes in the shape of your tongue, back of your throat and upper esophagus to assess the muscular activity during swallowing.

You will be asked to use CPAP during your standard videofluoroscopic swallowing study.

Who can participate

Inclusion criteria:

  • Patients at least 2 months after total laryngectomy
  • Undergoing Video Fluoroscopic Swallowing Examination

Exclusion criteria:

  • Patients with 100% neopharyngeal stenosis
  • Patients with active cancer within 2 months of the study
  • Patients with pharyngocutaneous fistula
  • Vulnerable population: Adults unable to consent, Pregnant women, and Prisoners
Benefits and risks of participating
We cannot promise any benefits to you from your taking part in this research. Possible benefits include improvement of your difficulty in swallowing during the swallow study.

Discomfort from wearing the CPAP mask and stomach bloating.
This study involves a radiation exposure that is typical of other diagnostic tests using ionizing radiation. The amount of radiation exposure received in this study is below the levels thought to result in a significant risk of harmful effects.
You will not be compensated for taking part in this study.
Study duration and period
We expect that being in this research will add approximately an additional 10 minutes during the course of a routine videofluoroscopic swallowing study.
