Background:
Several behavioural voice treatment procedures have been suggested for unilateral vocal fold paresis. However, data regarding their effectiveness and efficiency are sparse. Here we compare the outcome of traditional voice treatment versus electrostimulation voice exercise.
Methods:
A total of 24 patients participated voluntarily in a prospective randomised trial. Vocal fold irregularity and maximum phonation time were used as dependent variables.
Results:
Statistical analysis indicated slight though not significant differences favouring electrostimulation supported vocal exercises.
Discussion:
Further studies are needed to fully explore the benefits and effectiveness of the various treatment procedures. These studies should include subjective parameters (voice handicap) as well as efficacy parameters.
