Background: Tumor/treatment-related internal lymphedema (IL) and/or external lymphedema (EL) are associated with functional deficits and increased symptom burden in head and neck cancer patients (HNCP). Previously, we noted association between EL/IL and patient-reported dysphagia using the Vanderbilt Head and Neck Symptom Survey (VHNSS) version 1.0. Objective: To determine the relationship between IL/EL and subjective and objective measures of swallowing function. Methods: Eighty-one HNCP completed: (1) VHNSS version 2.0, including 13 swallowing/nutrition-related questions grouped into three clusters: swallow solids (ss), swallow liquids (sl), and nutrition(nt); (2) physical assessment of EL using Foldi scale; (3) endoscopic assessment of IL using Patterson scale (n = 56); and (4) modified barium swallow study rated by dysphagia outcome and severity scale (DOSS) and in conjunction with a swallow evaluation by National Outcomes Measurement System (NOMS). Examinations were performed at varied time points to assess lymphedema spectrum, from baseline (n = 15, 18.1%) to 18 months post-therapy (n = 20, 24.1%). Results: VHNSS swallow/nutrition items scores correlated with NOMS/DOSS ratings ( p < 0.001). Highest correlation was with NOMS: ss (-0.73); sl (-0.61); nt (-0.56). VHNSS swallow/nutrition scores correlated with maximum grade of swelling for any single structure on Patterson scale: ss (0.43; p = 0.001); sl (0.38; p = 0.004); nt (0.41; p = 0.002). IL of aryepiglottic/pharyngoepiglottic folds, epiglottis, and pyriform sinus were most strongly correlated with VHNSS and NOMS ratings. NOMS/DOSS ratings correlated with EL (> = -0.34; p < 0.01). No meaningful correlations exist between VHNSS swallow/nutrition items and EL (< -0.15, p > 0.20). Conclusions: IL correlated with subjective and objective measures of swallow dysfunction. Longitudinal analysis of trajectory and impact of IL/EL on dysphagia is ongoing.

In this study of adults who underwent open airway reconstruction, all returned to their preoperative diet, but those without stents had a shorter duration of dysphagia symptoms than those with stents. Approximately half as many patients with a stent had a prolonged course with dysphagia symptoms compared with those without a stent.
