Resumen
Background. To describe demographic factors and voice quality parameters of patients with unilateral vocal fold paralysis (UVFP) after a voice therapy protocol.Methods. Forty-seven patients with a diagnosis of UVFP by video-laryngoscopy were included. Voice therapy was applied to all patients during 15 sessions that were structured in three progressive stages. The objective was to train patients in vocal techniques, phonic-breathing coordination, blow control, vocal exercises for glottic closure and vocal setting. Glottal closure, Voice Handicap Index-10 for perception of voice impairment and GRBAS scale were used before and after the speech therapy.Results. The average age was 51 years (range 20-80), 60% women. Surgery was the most frequent cause (72%), and 40% had a profession related to voice use. Median time from diagnosis to treatment was 5 months (2-12). After voice therapy, 80% had complete glottal closure, previously this had been 34% (p<0.001), the score of VHI-10 decreased from 24.24 to 16.09 points (p<0.001) and GRBAS values improved in all the qualities of voice (p<0.001). Only 8.5% of the patients required surgical intervention after treatment.Conclusions. Voice therapy is effective as first line therapy in patients with UVFP, reserving medialization with non-absorbable material or thyroplasty surgery for those with a poor outcome. However, it is necessary to reduce the time it takes the patient to reach the Voice Unit after laryngoscopic diagnosis.Keywords. Unilateral vocal fold paralysis. Voice therapy.
