ABSTRACT
Background and Objectives
This study aims to conduct post-voice therapy to patients with unilateral vocal fold paralysis for vocal improvement, motility recovery and analyze the results.
Materials and Methods
Voice therapy was conducted to 13 patients who had shown response to voice therapy amongst 98 patients diagnosed with unilateral vocal fold paralysis. In order to be able compare before and after perceptual, acoustic and aerodynamic evaluations were conducted after voice therapy. Also, by using dysphagia checklist, we have verified whether if the patient had dysphagia prior to voice therapy. The therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic.
Results
All 13 patients who underwent voice therapy had shown improvements that are statistically significant from 4 scales excluding the S scale from auditory perception evaluation (p<0.05), with enhanced glottal contact. In acoustic evaluation, Jitter, Shimmer and NHR had shown significant improvement after voice therapy. MPT was also notably improved among aerodynamical evaluation (p<0.001). All 11 patients had with dysphagia prior to voice therapy reported to have improved swallowing functions.
Conclusion
Application of adequate voice therapy to patients with unilateral vocal fold paralysis, is an effective method that might be employed in the initial phase. Especially, the voice therapy proposed in this study is expected to be useful for patients in hypertension status due to secondary compensation after initial paralysis, since it focuses on improving vocal symptoms in a calm state with the supraglottis sufficiently relaxed. Also, the therapy is expected to be effective for improving swallowing functions.
