Аннотация
Prosthesis-assisted tracheo-esophageal speech has proven its value in post-laryngectomy voice rehabilitation, although manual occlusion of the tracheostoma during speech is necessary. In contrast a tracheostoma valve enables hands-free speech. We have now had experience with 30 patients using the Blom-Singer tracheostoma valve for more than 6 months 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 resistance.
