Abstract
Laryngectomized patients have a very important limitation when they lose the vocal function. Voice rehabilitation is fulfilled by means of the esophageal voice or by means of a phonatory prosthesis. Both methods are useful but they have evident differences concerning the vocal quality obtained. ObjectiveDetermine how rehabilitated voice is perceived with both methods by patients and observers, completing the study with its acoustic analysis. Material and methodLaryngectomized patients (n=18) with rehabilitated voice by means of esophageal voice (n=10) and phonatory prosthesis (n=8). A study was made through the VHI-30, acoustic analysis (F0, TMF,HNR, “speech rate”, intensity and spectrogram) and perceptual evaluation (GRBAS and CAPE-V). ResultsVHI-30 displays similar values in both types of rehabilitated voice. The acoustic analysis shows differences between both types of rehabilitated voices and the usual laryngeal voice. The perceptual study presents a higher degree of affectation on the esophageal voice than on the PF one. There is no relation between what the patient perceives and what the observer values. The acoustic and perceptual studies show closer values to normality in the phonatory prosthesis voice.
