Determining Swallow Outcomes in Head & Neck Lymphedema Subjects Receiving Early Intervention With Pneumatic Compression

Inclusion Criteria: 1. Age ≥ 18 years 2. A previous diagnosis of oropharyngeal carcinoma requiring treatment with radiation therapy 3. Diagnosis/evidence of lymphedema stage 1a or higher by clinical presentation based upon MD Anderson Cancer Center Head and Neck Lymphedema rating scale 4. EAT-10 score \>4 at Baseline and Randomization Visits (prior to randomizing subject) 5. The head and neck garments must fit appropriately (for patients with a tracheostomy, the fit will be assessed to ensure that the garments do not interfere with their tracheostomy) 6. Ability to perform swallow exercises 7. Willing and able to comply with the study protocol requirements and all study-related visit requirements 8. Willing and able to provide informed consent prior to study participation Exclusion Criteria: 1. Synchronous treatment for cancer (may or may not have successfully complete prior cancer treatment) 2. Other known causes of dysphagia such as previous radiation to the head and neck, or neuromuscular or neurodegenerative known to have a strong association with dysphagia (i.e., Parkinsons, ALS, MS, OPMD) 3. Poorly controlled: kidney disease (glomerular filtration rate \< 30 mls per minute), hypoproteinemia, pulmonary hypertension, hypothyroidism or parathyroidism, cyclic edema, or Munchausen Syndrome (for which endocrinologist recommends against neck compression) 4. Carotid sinus hypersensitivity syndrome 5. Symptomatic carotid artery disease, as manifested by a recent transient ischemic attack (within 30 days), ischemic stroke, or amaurosis fugax (monocular visual ischemic symptoms or blindness) 6. Symptomatic bradycardia in the absence of a pacemaker 7. Internal jugular venous thrombosis (within 3 months) 8. Increased intracranial pressure or other contraindications to internal or external jugular venous compression 9. Acute radiation dermatitis, unhealed surgical scar, unhealed or open wounds, surgical flap less than 6-8 weeks post-operative 10. Facial or head and neck dermal metastasis 11. Acute infection/inflammatory disease of the head and neck region (e.g., facial infection, parotid gland abscess, acute cellulitis, or other uncontrolled skin/untreated head and neck inflammatory skin disease) 12. Any condition in which increased venous and lymphatic return is undesirable 13. Heart failure (acute pulmonary edema, decompensated acute heart failure) 14. Subject is pregnant or trying to become pregnant 15. Acute venous disease (acute thrombophlebitis, acute deep venous thrombosis, acute pulmonary embolism) 16. The subject has comorbidities which, in the opinion of the investigator, will not be appropriate for the study or the subject has an estimated life expectancy of less than 1½ months 17. Any subject who is considered to be part of a vulnerable population (e.g., prisoners or those without sufficient mental capacity) 18. The subject has participated in any investigational drug or device research study within 30 days of enrollment
