The influence of a heat and moisture exchanger (HME) on the respiratory symptoms after total laryngectomy was studied in 42 patients. A significant reduction was found in the mean daily frequency of sputum production, forced expectoration in order to clean the airway and stoma cleaning after use of the HME for 6 weeks. Symptoms of fatigue and malaise decreased significantly, while social contact improved. Patients using oesophageal speech or an electrolarynx benefited more than patients using a voice prosthesis. The findings indicate that respiratory problems after total laryngectomy can be reduced significantly with the use of a device with heat and moisture exchanging properties. In turn, reduction of respiratory symptoms results in an improved quality of life.
