The aim of this study was to assess the clinical experience of three Italian centers using the third generation Provox Vega prosthesis, in terms of device life and voice outcome, comparing the results with the second generation Provox 2 prosthesis in the same sample. A prospective multicenter crossover study was performed in three phases. In the first phase we performed a reassessment, for enrollment purposes, of patients who were categorized into four different groups [normal – group A; radio-treated – group B; gastroesophageal reflux disease (GERD) – group C; and elderly subjects – group D]. In the second and third phases, all patients were monitored for prosthetic device life and assessed for objective and subjective voice characteristics after introducing Provox 2 and Provox Vega prostheses. In patients with Provox 2 prosthesis, the mean life was 165 days in group A, 148 days in group B, 91 days in group C and 188 days in group D. In Provox Vega patients, mean in situ prosthesis life was 213 days in group A, 182 days in group B, 118 days in group C and 227 days in group D.

In this paper, we report the first multicenter crossover study comparing different prosthetic models in the same patients, categorized in relation to different typologies of tracheoesophageal rehabilitative status. Result analyses confirmed an optimal stability of the Provox Vega compared to the Provox 2, in terms of device life and perceptual voice parameters.

Abstract

The aim of this study was to assess the clinical experience of three Italian centers using the third generation Provox Vega prosthesis, in terms of device life and voice outcome, comparing the results with the second generation Provox 2 prosthesis in the same sample. A prospective multicenter crossover study was performed in three phases. In the first phase we performed a reassessment, for enrollment purposes, of patients who were categorized into four different groups [normal – group A; radio-treated – group B; gastroesophageal reflux disease (GERD) – group C; and elderly subjects – group D]. In the second and third phases, all patients were monitored for prosthetic device life and assessed for objective and subjective voice characteristics after introducing Provox 2 and Provox Vega prostheses. In patients with Provox 2 prosthesis, the mean life was 165 days in group A, 148 days in group B, 91 days in group C and 188 days in group D. In Provox Vega patients, mean in situ prosthesis life was 213 days in group A, 182 days in group B, 118 days in group C and 227 days in group D. The perceptual voice data showed a better rating across all parameters for the Provox Vega samples compared to those of Provox 2. In this paper, we report the first multicenter crossover study comparing different prosthetic models in the same patients, categorized in relation to different typologies of tracheoesophageal rehabilitative status. Result analyses confirmed an optimal stability of the Provox Vega compared to the Provox 2, in terms of device life and perceptual voice parameters.
