Summary
This is an investigator initiated prospective study to determine whether the use of a negative pressure suction in the hypopharynx will reduce the amount of aspiration during Video Fluoroscopic Swallowing Exam (VFSE) among patients with oropharyngeal dysphagia.
Description
During a properly coordinated swallow, the oropharynx, larynx, and hypopharynx undergo a series of movements that serve to prepare and expand the pharyngoesophageal segment (PES), which is the inlet into the esophagus. Under normal circumstances, a food bolus is safely propelled from the oropharynx, through the PES, and into the esophagus. Surgical and radiation therapy in the head and neck, as well as deficiencies such as poor coordination, mistiming, or obstructing lesions may prevent the food bolus from safely entering the esophagus and instead diverting toward the trachea.
A number of patients with severe oropharyngeal dysphagia are not able to tolerate any diet without risking aspiration and subsequent pneumonia, often to a degree severe enough that they cannot manage to safely swallow their secreted saliva. These patients depend on a gastrostomy feeding tube in order to obtain adequate daily nutritional requirements and must suction or spit out their saliva to prevent aspiration and a sensation of asphyxiation. Despite these precautions, many of these patients ultimately suffer life-threatening pneumonia. Investigators will be testing if the use of use of a negative pressure suction in the hypopharynx will reduce the amount of aspiration during Video Fluoroscopic Swallowing Exam (VFSE) among patients with severe oropharyngeal dysphagia
