A prospective study of speech and voice rehabilitation after total laryngectomy with the low-resistance Groningen, Nijdam and Provox voice prostheses.
In a prospective study the Groningen, Nijdam, and Provox voice prostheses were evaluated with respect to speech and voice rehabilitation. At approximately 1, 4, and 10 months after operation, patients were submitted to a standardized speaking task to evaluate phonatory skills (phrase length, phonation duration, dynamics on tone, dynamics on sentence, speech rate and availability of sound), speech quality (fluency and overall intelligibility), voice quality and stoma technique (stoma noise). Tracheoesophageal speech rehabilitation proved to be successful in 94-100% of patients, as measured at approximately 10 months after operation. Furthermore, no significant overall differences were found between the three prostheses. There was a significant improvement in time for speech rate and stoma noise. As for the time effects (e.g. improvement in performance over time) no differences between the three prostheses were found.
