ABSTRACT
OBJECTIVE: A multicenter study based in the United States assessed the heat-moisture exchanger effect on respiratory symptoms and "voice quality" of laryngectomees. PATIENTS AND MEASURES: The study group consisted of 81 consecutive laryngectomees (62 men and 19 women; mean age, 66 years; age range, 45 to 89 years), with a median follow-up of 3.5 years (range, 0.5 to 24 years). A structured questionnaire was used to assess 3-month results, and tally sheets recorded the frequency of cough-expectoration during first and last trial weeks. RESULTS: Compliance was 73% (n = 59); decrease in coughing, 68%; sputum production, 73%; forced expectoration, 60%; and need for stoma cleaning, 52% of these 59 patients. Regarding daily cough-expectoration frequency, a statistically significant decrease (P < 0.0001) was found between the first and last trial weeks. Regarding influence on voice quality, 46% of regular users reported improvement in intelligibility, 30% in loudness, 37% in fluency, and 40% in telephone intelligibility. Fourteen patients (19%) reported skin irritation, with discontinuation of 7 patients. CONCLUSION: The observed decrease in pulmonary symptoms and improvement in voice quality confirm earlier reports from the Netherlands, United Kingdom, and Spain indicating improvement in postlaryngectomy quality of life.

BACKGROUND: Head and neck cancer treatment with high-dose chemoradiation may cause xerostomia and affect the patient's perception of swallowing ability. METHOD: Whole saliva production was measured in 36 patients with advanced-stage cancer of the oropharynx before treatment and 3 months after treatment by weighing a 4 x 4 inch gauze before and after a 2-minute chewing period. Presence of multiple eating difficulties was measured by patient interview. Swallowing was examined videofluorographically (VFG). RESULTS: Saliva weight decreased from a mean (SEM) of 5.1 (0.5) g pretreatment to 1.4 (0.5) g after treatment (p<.0001). At 3 months, significantly more patients perceived difficulty swallowing, dry mouth, needing water while eating, food stuck in the mouth or throat, and change in taste. Saliva weight was not correlated with VFG measures of bolus transit or observations of residue. CONCLUSIONS: Chemoradiation treatment results in xerostomia and a significant increase in patient perception of swallowing difficulties. Saliva weight in patients who perceive swallowing problems was lower. Xerostomia did not affect the physiologic aspects of bolus transport. Xerostomia affected the sensory process and comfort of eating more than bolus transport.
