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.
The article presents the results of a study of the acoustic characteristics of the voice in voice professionals and non-voice professionals. We examined 80 people aged 23 to 45 years with functional dysphonia of the hypotonic type, who applied to the phoniatric office of the St. Petersburg Research Institute of ENT. Of these, 23 were professional vocalists, 12 were representatives of speech professions, and 45 were non-professional voices. First, the phoniatrist examined the larynx and assessed its condition with video endostroboscopy (K. Storz) or video pharyngolaryngoscopy (VIVIDEO, KayPentax). Objective acoustic analysis was performed using the Multi-Speech software and hardware complex and the MDVP software (KayPentax). The numerical and graphical expressions of the following parameters were evaluated: noise-to-harmonic ratio (NHR), voice turbulence index (VTI), and soft phonation index (SPI). The results of the study showed that the SPI index is the most informative in assessing hoarseness in patients with hypotonic functional dysphonia. The lower values of this indicator in vocalists can be explained by the presence of a sufficiently developed resonator system of the vocal apparatus, which is reflected in the amplification of the high-frequency components of the voice spectrum.
We have undertaken the electron microscopic investigation into peculiarities of six tumour-like structures on the vocal cords. The study has demonstrated changes in the number and distribution patterns of intercellular junctions, keratin and tonofilament contents in epithelial cells, basal membrane structure, and composition of the basic substance in lamina propria. All the examined tumour-like structures contained bacteria an two of them had viral particles in vacuoles of fibroblasts. Moreover, the bacteria were found on the surface of epithelium, between epithelial cells and in the basic substance in lamina propria. Cytoplasm of epithelial cells and fibroblasts not infrequently contained bacteria in the phase of division.
The article is devoted to a rare ENT disease. The introduction deals with pathogenesis, classification, and clinical course of ALamyloidosis, which is in most cases diagnosed in the larynx diseases. The article presents three authors’ own clinical cases of vestibular, vocal and sub-vocal larynx amyloidosis.
