Swallowing Expansion Device
Titanium swallowing expansion device
Device: Swallowing Expansion Device
SED looks like the letter "T" and has a plate and a post. The plate is like the top part of the "T" or smooth part of the tack. The plate is attached to the cartilage or flexible connective tissue of the throat. The SED post is like the bottom part of the "T" with a small ring. The post permanently sticks out from the throat, like a skin piercing. The SED is made out of titanium because this metal is extremely strong and commonly used in medical devices put into the body, such as hip joints or bone plates.
Other Name: SED
- Change in Upper Esophageal Sphincter (UES) Opening [ Time Frame: Before implantation, 2 months and 2 years post implantation ]UES opening will be measured via fluoroscopy. A digital still image will be captured at the point of maximum UES opening with and without anterior traction of the SED. The software will be calibrated to the known length of the SED that is visible in the fluoroscopic image. The distance between the anterior and posterior pharyngo-esophageal segment at the point of maximum UES opening will be measured. If swallowing is improved and there is no aspiration, the patient will be taught how to coordinate pulling the SED with the correct amount of force at the appropriate time during swallowing.
- Change in Penetration Aspiration Scale (PAS) [ Time Frame: Before implantation, 2 months and 2 years post implantation ]Swallowing safety will be assessed with the Penetration Aspiration Scale (PAS) via videofluoroscopy. A scale of 1 indicates a safe swallow (material does not enter the airway). A score of 2-3 indicates mild, 4-5 moderate, and >5-8 indicates severe swallowing disability (material enters the airway, it passes below the vocal folds, and no effort is made to expel it). The patient is initially fed a 1 cc bolus of thin barium. If no aspiration is detected, the patient is then administered a 3 cc and then 20 cc bolus, or largest bolus possible, of barium. If any aspiration is detected at any stage of the study, the procedure is terminated immediately. The PAS will be calculated for the largest swallowed bolus size on fluoroscopy.
