Effects of Voice Therapy in Early Onset Unilateral Vocal Fold Paralysis in Our Tertiaty Care Centre

Unilateral vocal cord paralysis presents with dysphonia, shortness of breath and swallowing difficulty and occurs secondary to damage to the recurrent laryngeal nerve by causes such as viral infection, iatrogenic, trauma and idiopathic. The objective of this study was to study the efficacy of early voice therapy in the management of patients with unilateral vocal fold paralysis. Total 116 patients in previous two years were included in this retrospective study suffering from unilateral vocal fold paralysis. They were subjected to a protocol of voice evaluation including Voice handicap index, Maximum phonation time and S/Z ratio. Patients were also examined using Hopkins Examination. All patients included received voice therapy for 6-month duration in 24 sessions. Patients who had started voice therapy early during their symptoms within few days or 1 to 2 weeks had better outcomes regarding Voice handicap index, Maximum phonation time and S/Z ratio than patients who had started voice therapy at 1 to 1.5 month after symptom onset. Early onset voice therapy may enhance the reduction in glottal gap and improvement of voice quality by hindering the development of faulty hyper functional compensatory behaviors; early voice therapy may therefore enhance the patient's quality of life.
