Abstract

Introduction: The aim of this study is to analyze objectively and subjectively voice quality in patients with unilateral vocal cord paralysis in pre and post vocal rehabilitation phase. Methods: A retrospective study through vocal analysis of 18 patients, 4 male and 14 female, mean age 50 years, evaluated by an otolaryngologist Voice consultation and diagnosis of unilateral paralysis of the vocal cord adduction. In the acoustic analysis, we used the software Dr. Speech, through the issue of sustained vowels / a /, / i / and / e / the F0 parameters were analyzed, SD F0, Jitter, Shimmer, Tremor, NNE and HNR. Audio-perceptive analysis was assessed by GRBAS and only analyzed dysphonia as the degree of severity (G) sustained vowel / a /, / i / and / and / and conversation. The maximum phonation time is obtained by an average of 3 issues of the vowels / a / and / i /. Patients began speech therapy, with one session per week and were reassessed after 12-15 sessions. A descriptive statistical analysis and inference testing was done. Results/Discussion: In the acoustic analysis found significant results in some of the vocal parameters, as well as the degree of dysphonia and maximum phonation time. Conclusions: Vocal rehabilitation and treatment of patients with unilateral vocal cord paralysis proves to be effective in lowering dysphonia, promoting improved acoustics, audio-perceptive and maximum phonation time. In the future it is considered important to a multidisciplinary approach, since laryngoplasty injection, the use of cutaneous electrostimulation associated with conventional voice therapy.
