ABSTRACT

Objective:

To investigate the clinical effect of voice training on the vocal function of patients with early vocal fold polyps.

Methods:

From May, 2016 to May, 2018, 80 patients with unilateral wide-based vocal fold polyps were randomly divided into control group (n = 40) and experimental group (n = 40). Both groups underwent voice hygiene education, and the experimental group accepted voice training, 40 minutes a week for twelve weeks in addition. They were evaluated with fiber laryngoscope, voice handicap index (VHI) and the computer phonatory detection before and after training.

Results:

Five in the control group and seven in the experimental group were dropped out. After training, the cure rate and the improvement rate of vocal fold polyps were significantly higher in the experimental group than in the control group (χ2 = 24.608, P < 0.001). The scores of VHI significantly improved in the experimental group (t/Z > 11.701, P < 0.05), and were better than those in the control group (t/Z > 7.027, P < 0.001). The scores of jitter, shimmer, and maximum phonation time improved (|t/Z| >5.012, P < 0.001) after training in the experimental group, and were better than those in the control group (t/Z > 4.596, P < 0.001).

Conclusion:

Voice training could improve the vocal function of patients with early vocal fold polyps, reduce hoarseness, and improve the voice quality.
