RESUMO
The objective of the present study was to evaluate the effectiveness of the application of homeovox for the combined treatment of small vocal cord nodules and acute laryngitis in the professional voice users. A total of 40 subjects presenting with dysphonia were examined after they were divided into two study groups and two groups of comparison depending on the nosological form of the pathological condition. The subjects comprising the study groups were given traditional therapy in the combination with the intake of homeovox whereas the patients included in the two groups of comparison received the traditional treatment alone. The outcome of the treatment was evaluated on days 1, 5, and 10 after the initiation of therapy based on the analysis of the changes in the videoendostroboscopic picture of the larynx and the acoustic characteristics obtained by the computer-assisted analysis of the voice. The analysis of the results of the combined treatment has demonstrated the statistically significant differences in some acoustic parameters of the voice between the subjects with small vocal cord nodules and acute laryngitis belonging to the study groups and the groups of comparison. It is concluded that the introduction of homeovox in the combined treatment of the patients presenting with the small nodules in the vocal cords and acute catarrhal laryngitis accelerates the recovery of the acoustic characteristics of the voice within various periods after the onset of the treatment in comparison with the patients treated with the use of traditional therapy alone.

OBJECTIVES/HYPOTHESIS: To assess the comparative effectiveness of botulinum toxin and propranolol in patients with essential vocal tremor (EVT). STUDY DESIGN: Individual prospective cohort study. METHODS: Study patients were recruited at the Emory Voice Center from patients seeking treatment for EVT. Exclusion criteria included current ß-blocker treatment, spasmodic dysphonia, or other disease that prevented the use of propranolol therapy. A 10-week washout period from prior botulinum toxin treatment occurred before enrollment. Patients were assessed via the Voice-Related Quality-Of-Life (VRQOL) questionnaire, Quality of life in Essential Tremor questionnaire, and blinded perceptual voice assessment. These assessments were made at baseline voice 2 weeks after propranolol therapy and 4 weeks after botulinum toxin injection. RESULTS: Eighteen patients were enrolled. After 2 to 4 weeks of propranolol therapy (with a maximum dosage of 60 mg to 90 mg per day), patients report an average ΔVRQOL of 9.31. Six patients report significant VRQOL improvement >10, with the rest reporting changes between -7.5 and 7.5. Fifteen patients were followed for at least 4 weeks after botulinum toxin injection, reporting an average improvement in scaled VRQOL of 22.00. Blinded perceptual voice assessment demonstrates an improvement in overall severity of tremor with botulinum toxin. CONCLUSIONS: In some patients with EVT, propranolol led to significant vocal improvement with no major side effects. Although botulinum toxin remains the gold-standard therapy for patients with EVT, propranolol represents a possible alternative or adjuvant therapy for certain patients.
