Background: Unilateral vocal fold mobility impairment (UVFMI) causes dysphonia and/or dysphagia, which can significantly affect a patient’s ability to communicate and perform regular daily life activities as well as the quality of life. Voice therapy offers a less invasive and more preferential method for patients. However, there are limitations concerning the integration of multiple therapy approaches. Voice therapy exercises with clear methodologies are required to plan and conduct therapy systematically, and frequency would be required for each exercise. Therefore, this study was conducted by applying the protocols of voice therapy in adult patients with unilateral vocal fold mobility impairment. Objective: This feasibility study is a prospective cohort, pre-post single arm, designed to determine whether the voice therapy protocol (VTP) can enhance voice quality in adult patients with unilateral vocal fold mobility impairment (UVFMI) in a pilot study. Materials and methods: All subjects received 12 sessions of voice therapy protocol, with each session conducted weekly for 45 minutes. The voice therapy protocol applied in this study consisted of vocal hygiene education, abdominal breathing exercises, vocal function exercises, pushing exercises, muscle relaxation exercises, and applied resonance voice therapy. The outcomes of protocols for voice therapy were measured before and after treatment using subjective voice assessments (GIRBAS scale) and objective voice assessments (Dr. Speech program and electroglottography-EGG). Results: Cases 2, 7, 10, 11, and 13 improved after receiving VTP. As for other participants, there are still some voice parameters that need to be monitored. Overall, it was found that the participants’ voice parameters were changing within the acceptable range, with MPT, jitter, shimmer, and HNR values significantly different (p<0.05). Conclusion: The findings of this study indicated that the voice therapy protocol was a worthwhile alternative and could be used to develop further treatment guidelines for adult patients with UVFMI at a speech clinic.

“…The greatest occurrence of lesions on the left side is associated with the difference in the anatomical course of the recurrent laryngeal nerve, which is long and partially intrathoracic, and it can also be affected by mediastinal diseases. When the paralysis predominates in the right side, usually the UVFP etiology is associated to a thyroidectomy sequela 14 .…”

“…Breathiness and the difficulty to communicate effectively are the greatest losses complained by patients with UVFP 11 . Other researchers define UVFP-related dysphonia as a weak, hoarse and breathy voice, with an increase in the fundamental frequency and limitations in speech sound intensity, stiffness and with voice little projection 9, 12 , 13 , 14 . Moreover, they may cause changes to swallowing, increase in the speech effort and vocal tiredness 9 , 15 , 16 .…”

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.
