“…The patient's voice will depend on the position of the paretic vocal fold in reference to the medial line, the presence and severity of muscle atrophy, as well as the compensatory mechanisms of the patient [6,7] as a hyperkinetic stereotype of ventricular phonation [8]. The literature states that women are more likely to encounter this pathology, especially if the paralysis is caused by surgical treatment of the thyroid gland [9][10][11].…”

Introduction: Dysphonic voice is present in patients with unilateral vocal fold paralysis (UVFP). The aim of this study is to present outcomes following rehabilitation of patients with UVFP, performed according to a voice therapy protocol. Methods: Prospective study comprised 27 women with UVFP who underwent pre and post voice therapy assessment. The mean age of patients was 53.19 ± 10.06 years. The protocol included: 1. multidimensional assessment of voice quality before treatment; 2. digital laryngeal manipulation voice therapy; 3. voice therapy evaluation which implied repeated multidimensional assessment of voice. Results: The results showed improvement in voice quality following voice therapy with regard to the parameters of the objective voice analysis (maximum fundamental frequency of voice, minimum intensity of voice, jitter, shimmer, harmonics-to-noise ratio and signal-to-noise ratio, p ˂ 0.05), maximum phonation time, subjective analysis of voice, as well as self-assessment of voice quality on all the subscales and overall score (p ˂ 0.001). Conclusion: Implementing a protocol provides clear guidelines at each stage of the treatment. Voice therapy performed using digital laryngeal manipulation improves the majority of the acoustic and perceptual characteristics of the voice.
