Early voice therapy in patients with unilateral vocal fold paralysis.

OBJECTIVE

The purpose of this work was to study the efficacy of early voice therapy in the management of patients with unilateral vocal fold paralysis.

PATIENTS AND

METHODS

Three groups of patients suffering from unilateral vocal fold paralysis were subjected to a protocol of voice evaluation including auditory-perceptual voice analysis, the Dysphonia Severity Index (DSI) and the 20-item Voice Problem Self-Assessment Scale (VPSS-20). Patients were also examined using video laryngostroboscopy. The early voice therapy group was enrolled in a voice therapy program for 16 sessions as soon as the patients were diagnosed; the second group of patients did not receive voice therapy during the course of their ailment. The late voice therapy group was enrolled in a voice therapy after a period of at least 6 months following the onset of vocal fold paralysis. All studied patients were reevaluated after a period of 2 months.

RESULTS

The early voice therapy group showed better outcomes regarding VPSS-20 scores, auditory-perceptual voice analysis as well as the DSI.

CONCLUSION

Early onset of voice therapy may enhance the reduction in glottal gap and improvement of voice quality by hindering the development of faulty hyperfunctional compensatory behaviors; early voice therapy may therefore enhance the patient's quality of life.
