Speech and voice analysis after near-total laryngectomy and tracheoesophageal puncture with implantation of Provox 2 prosthesis.
Vocal characteristics were compared in two groups of patients who were operated on due to laryngeal cancer. One group was composed of patients after near-total laryngectomy and the other after total laryngectomy followed by tracheoesophageal puncture with implantation of Provox 2 prosthesis. Acoustic analysis was carried out using the EZ Voice Plus program and included the following parameters: fundamental frequency, jitter, shimmer, harmonic to noise ratio, range of fundamental frequency, maximal phonation time and intensity.
