Automatic speaking valve in speech rehabilitation for laryngectomized patients

For speech rehabilitation after total laryngectomy, the Provox FreeHands Heat and Moisture Exchanger (FreeHands HME; Atos Medical AB, Hörby, Sweden) was compared with the Provox Heat and Moisture Exchanger (HME), and the patients’ Health-Related Quality of Life (HRQoL) was assessed. A review of the English literature was performed considering automatic speaking valves. The study design was a cohort study. Fourteen laryngectomized male patients who had used the HME successfully before receiving the FreeHands HME entered the study. An ENT specialist and a speech pathologist examined these patients. Data concerning voicing, breathing, skin adhesion, voice and speech quality, and HRQoL were collected by a structured questionnaire. Voice recordings were performed for evaluation of the quality of the voice. A computer-aided search of the MED-LINE database was conducted, supplemented by hand searches of key journals. Twelve patients had used the FreeHands HME on special social occasions and reported three main reasons why FreeHands HME was unsuitable for continuous use: heavier breathing, more difficult speaking, and worse subjective quality of voice. With HME, phonation time tended to be longer and the softest phonation softer ( P =0.034). The loudest phonation was louder with FreeHands HME ( P =0.015). Patients’ HRQoL assessed by the 15D profile was similar to that of the age- and sex-matched male Finnish general population (patients 0.877, population 0.884). A review of the literature showed few works dealing with automatic speaking valves. The FreeHands HME is a useful additional device in a selected group of laryngectomized patients. Total laryngectomy did not lower patients’ HRQoL notably.
