Voice and vocal fold position in men with unilateral vocal fold paralysis.

UNLABELLED

The paralyzed vocal fold positioning and the degree of dysphonia are important inputs when one is deciding upon treatment options for unilateral vocal fold paralysis (UVFP).

OBJECTIVE

To check voice characteristics and paralyzed vocal fold position in men with UVFP.

MATERIALS AND METHODS

This is a retrospective historical cross-sectional cohort study, with data from 24 men with UVFP with mean age of 60.7 years, submitted to voice assessment by three speech therapists and three ENT physicians used laryngeal images to classify the position of the paralyzed vocal fold.

RESULTS

The paralyzed vocal fold was found in the paramedian position in 45.83% of the cases; in the intermediary position in 25%; lateral in 20.83%, and it was in the median position in 4.16%; the dysphonia resulting from the UVFP was characterized by moderate hoarseness, roughness and stress in the voice; breathiness (most had severe breathiness); weakness and instability(mostly mild); the position of the paralyzed vocal fold had a significant influence on the general degree of vocal deviation.

CONCLUSION

The general degree of dysphonia is associated with the paralyzed vocal fold position; dysphonia is characterized by hoarseness, breathiness, roughness and stress of moderate to severe levels.
