Internal Lymphedema Correlates with Subjective and Objective Measures of Dysphagia in Head and Neck Cancer Patients.

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.

Dysphagia Following Airway Reconstruction in Adults.

IMPORTANCE: Patients who undergo open airway reconstruction procedures are likely to experience some degree of postoperative dysphagia symptoms and delayed return to oral intake. OBJECTIVE: To review the duration of postoperative dysphagia symptoms and outcomes in a group of adult patients. DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of the medical records of adult patients undergoing laryngotracheoplasty, posterior cricoid split laryngoplasty, tracheal resection, and cricotracheal resection in a tertiary hospital between July 2009 and September 2014. EXPOSURES: Laryngotracheoplasty, posterior cricoid split laryngoplasty, tracheal resection, and cricotracheal resection. MAIN OUTCOMES AND MEASURES: Demographic characteristics, etiology of airway stenosis, surgical procedure, stent type, and duration of dysphagia symptoms. RESULTS: Thirty-eight patients (14 men, 24 women; mean [SD; range] age, 48 [14.4; 20-80] years) fitting the inclusion criteria were identified. Twenty-four (63%) patients had laryngotracheal stenosis secondary to prolonged intubation, with 3 (8%), 5 (13%), and 6 (16%) cases being due to autoimmune, idiopathic, or other etiology, respectively. Twenty-five (66%) patients underwent tracheal or cricotracheal resection, and 13 (34%) underwent laryngotracheoplasty or posterior cricoid split laryngoplasty. Of the 17 patients with stents placed, 6 (35%) patients had a suprastomal stent sewn at the top with a polypropylene suture using a horizontal mattress technique, 6 (35%) patients had a suprastomal stent capped with an extended Silastic thoracic T-tube segment, and 5 (29%) patients had either a T-tube or hood bronchial stent. Eight of 17 patients used a nasogastric feeding tube while the stent was in place (up to 5 weeks). All patients returned to their preoperative diet. The mean (SD) duration of dysphagia symptoms in all patients (both those without a stent and following stent removal) was 8 (27.2) days (median, 1.5 days). The mean (SD) duration of dysphagia symptoms in patients who did not have a stent placed was 4.8 (5.3) days (median, 4 days). CONCLUSIONS AND RELEVANCE: 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.
