Fja. Vandenhoogen et al., THE BLOM-SINGER TRACHEOSTOMA VALVE AS A VALUABLE ADDITION IN THE REHABILITATION OF THE LARYNGECTOMIZED PATIENT, European archives of oto-rhino-laryngology, 253(3), 1996, pp. 126-129
Prosthesis-assisted tracheo-esophageal speech has proven its value in
post-laryngectomy voice rehabilitation, although manual occlusion of t
he tracheostoma during speech is necessary. In contrast a tracheostoma
valve enables hands-free speech. We have now had experience with 30 p
atients using the Blom-Singer tracheostoma valve for more than 6 month
s and have found that most patients prefer prosthesis-assisted speech
with the tracheostoma valve. Measurement of several speech parameters
with digital and valve occlusion of the tracheostoma did not show any
significant differences between the two speaking conditions. Problems
included maintenance of an airtight seal, outward forcing of the valve
diaphragm during forced expiration and subjective increased airflow r
esistance.
