Intelligibility and Psycho-Social Adjustment. A Comparison Between Patients with Oesophageal Voice and Patients with a Voice Prosthesis
In this study, the results of 2 voice restoration methods are compared: oesophageal speech and surgical voice restoration via voice prosthesis (Herrmann prosthesis). Three criteria were employed to evaluate the results: (a) intelligibility, (b) the patients’ own rating of how well different target persons understood him, and (c) general psycho-social adjustment. The working hypothesis that “patients with a prosthesis have better results than oesophageal speakers in all respects” is examined. Test intelligibility is assessed by using the post-laryngectomy telephone test (PLTT, Zenner, this volume, p. 148). The results are shown in Table 1.
