The mucus layer on the vocal folds was examined by videostrobolaryngoscopy in patients with laryngeal tension-fatigue syndrome, a chronic functional dysphonia due to vocal abuse and misuse. Besides the findings in previous reports (such as abnormal glottal closure, phase or amplitude asymmetry, and the irregular mucosal wave), the vocal folds during vibration had an uneven mucus surface. The occurrence of an uneven mucus layer on vocal folds was significantly greater in subjects with this voice disorder (83% or 250 of 301 patients in this series) than in those without voice disorders (18.5% or 5 of 27). The increase of mucus viscosity, mucus aggregation, and the formation of rough surfaces on the vocal folds alter the mechanical properties that contribute to vibration of the cover of the vocal folds, and thereby worsen the symptoms of dysphonia in patients with laryngeal tension-fatigue syndrome.

Voice is a work tool for many professional groups. Currently, cases of dysphonia of multiple origin consist a growing issue. Voice disorders may result from disturbed voice production process, congenital defects, post-traumatic conditions, chronic diseases or hormonal disorders. Chronic diseases causing voice disorders include laryngopharyngeal reflux disease and esophageal reflux disease. The chronic character of reflux causes the formation of numerous morphological changes of the larynx, including: hyperemia of the mucosa limited to arytenoid and intraarytenoid area, edema of the vocal folds, edema of the larynx mucosa. These changes contribute to voice disorders. Among the pathological changes of voice organ etiologically associated with reflux, the following disease units may be distinguished: reflux laryngitis, subglottic edema, contact ulceration, larynx granuloma, larynx and pharynx cancer. Many of disorders in the upper respiratory tract are etiologically related to reflux, e.g. dysphonia, grunting, coughing and dyspnoea.

Purpose High-speed videoendoscopy (HSV) is an emerging, but barely used, endoscopy technique in the clinic to assess and diagnose voice disorders because of the lack of dedicated software to analyze the data. HSV allows to quantify the vocal fold oscillations by segmenting the glottal area. This challenging task has been tackled by various studies; however, the proposed approaches are mostly limited and not suitable for daily clinical routine. Method We developed a user-friendly software in C# that allows the editing, motion correction, segmentation, and quantitative analysis of HSV data. We further provide pretrained deep neural networks for fully automatic glottis segmentation. Results We freely provide our software Glottis Analysis Tools (GAT). Using GAT, we provide a general threshold-based region growing platform that enables the user to analyze data from various sources, such as in vivo recordings, ex vivo recordings, and high-speed footage of artificial vocal folds. Additionally, especially for in vivo recordings, we provide three robust neural networks at various speed and quality settings to allow a fully automatic glottis segmentation needed for application by untrained personnel. GAT further evaluates video and audio data in parallel and is able to extract various features from the video data, among others the glottal area waveform, that is, the changing glottal area over time. In total, GAT provides 79 unique quantitative analysis parameters for video- and audio-based signals. Many of these parameters have already been shown to reflect voice disorders, highlighting the clinical importance and usefulness of the GAT software. Conclusion GAT is a unique tool to process HSV and audio data to determine quantitative, clinically relevant parameters for research, diagnosis, and treatment of laryngeal disorders.

Presbylarynx refers to age-related structural changes of the vocal folds that include muscle atrophy, reduced neuromuscular control, loss of superficial lamina propria layer, and reduced pliability. The changes result in thin and bowed vocal folds, increased vocal effort requirements, breathy voice, change in habitual pitch, and strain. The primary treatment options are voice therapy focused on strengthening breath support and the intrinsic muscles of the larynx, and optimization of resonance; injection augmentation of the vocal folds; and type I thyroplasty. Functional dysphonia is defined as change in voice quality in the absence of structural or neurological abnormalities of the larynx. Muscle tension dysphonia (MTD) is a subtype of functional voice disorders and involves laryngeal muscle tension imbalance due to excessive or dysregulated activation resulting often in strained or breathy voice. MTD can be divided into primary (psychological etiology or vocal misuse) and secondary (compensatory for organic laryngeal pathology). The mainstay of treatment for MTD is voice therapy, along with medical or surgical treatment of the underlying vocal pathology in secondary MTD. Mutational falsetto, or puberphonia, is a functional voice disorder where a high-pitched, pre-adolescent voice fails to transition to the lower pitch of adulthood.

The work assessed the clinical utility of open quotients measured during laryngovideostroboscopy and electroglottography. Values of the parameters were analyzed according to clinical diagnosis. An algorithm based on direct and indirect mucosal wave measurement is presented, which allows for differentiation of voice disorders. The method developed for the objectification of glottal functions in various voice pathologies is characterized by high sensitivity and specificity.

Objective: To investigate the risk of mental distress during the COVID-19 pandemic in individuals of the voice-speech professions and the possibility of its impact on voice function and quality of life. Materials and Methods: The study involved 33 people of voice-speech professions who were treated at the University Clinic of Zaporizhzhia State Medical University in 2020. The presence of mental disorders was determined by questionnaires using the hospital anxiety and depression scale (HADS). The patients were divided into 2 groups, depending on the absence and presence of significantly expressed symptoms. A specialized phoniatric examination using functional loads (measuring the time of maximum phonation (PMF), perceptual assessment of the voice according to the GRBAS scale), videostroboscopy of the larynx were carried out. The assessment of the mental impact of voice disorders on the quality of life was carried out according to the Voice Handicap Index (VHI) questionnaire. The statistical significance of the comparative indicators and the connection of their changes were established using the Spearman's rank correlation coefficient. Results: It was found that among the surveyed 33 people, 22 patients (group 1) had subclinical anxiety and depression, and 11 (group 2) had no significant symptoms. Patients with subclinically severe mental disorders (n = 22) showed a significant increase in the emotional indicator by 85.37% (p≤0.01). A high positive relationship was found between subclinical levels of anxiety and depression and disturbances in the phonatory cycle of the larynx. When conducting a Spearman correlation analysis between the data of perceptual assessment of the voice according to the GRBAS system, data of video stroboscopy of the larynx, indicators of anxiety and depression, and the results of the VHI questionnaire, a positive relationship of a high degree was established between the level of anxiety and vibratory insufficiency of the vocal folds (rs=0.95; p≤0.05), negative with the Navy (rs=-0.59; p≤0.05), as well as physical (rs=0.75; p≤0.05) and emotional (rs=0.79; p≤0.05) components of average quality of life. The data obtained indicate a significant effect of subclinical disorders of the mental state on impaired voice function and the emotional component of the quality of life in persons of vocal-speech professions. Conclusions: Screening of mental health in persons of voice-speech professions together with a baseline assessment of voice function and quality of life are important steps for monitoring potential voice disorders and the formation of risk groups in order to carry out preventive and therapeutic measures for voice disorders.

The human vocal folds are responsible for sound production during normal speech, and a study of their flow-induced vibrations can lead to improved prevention and treatment of voice disorders. However, studying the vocal folds in vivo or using excised larynges has several disadvantages. Therefore, alternatives exist using either synthetic (physical) and/or computational vocal fold models. In order to be physiologically relevant, the behavior and properties of these models must reasonably match those of the human vocal folds.

Purpose The purpose of this study was to determine and demonstrate the need for structured vocal training/seminars for fitness professionals to prevent voice disorders and improve overall voice use during instruction. Method Approximately 230 fitness professionals responded to an anonymous online questionnaire consisting of 20 items addressing voice care, voice use, vocal demands, and self-reported vocal difficulties within the fitness instructor role. The survey was distributed via SurveyMonkey, and the answers contributed to the data results (see Appendix ). Results The data display overwhelming agreement among fitness professionals that voice has an important role in and major impact on every class. The majority of respondents consider themselves occupational voice users but affirm they have never had a vocal training, although they feel a vocal training would be beneficial for their work in the fitness industry and they would be interested in attending such a training. A majority of respondents also teach three or more classes per week and qualify as “vocal athletes.” Over half of the respondents perceive themselves to be inadequately hydrated, and the majority also report hoarseness at some point related to their jobs teaching fitness classes. A majority of those surveyed have experienced a feeling of straining the voice/using effort during and/or after instruction of classes and also report being social/talkative individuals outside class instruction—therefore displaying a consistent use of voice in and outside their “work” setting, implying high vocal demand and full vocal schedules with reduced time for vocal rest. Conclusions The results of this study indicate that there is an imperative need to educate and empower fitness professionals to take adequate care of their voices and use their voices in the most healthy, efficient, effective, and dynamic ways possible to create outstanding classes, motivate clients, and protect their instrument (larynx/vocal folds) while doing so.

AbstractIntroduction:Office-based laryngeal injection for the treatment of a variety of voice disorders is an established practice. Various methods of delivery to the vocal folds are in practice.Aim:We present a simple and repeatable method of injecting botulinum toxin into the larynx.Method:Botulinum toxin A (Botox®) was delivered into the larynx using a channelled fibre-optic laryngoscope under local anaesthetic, in an office setting.Results:Seven patients received regular botulinum toxin injections, via our preferred method. The treatment intervals and dosage regime varied depending on patient requirements. The procedure was carried out in an office setting, with minimal discomfort and inconvenience to the patient.Conclusion:We present a method of botulinum toxin delivery to the larynx which is simple, easily repeatable and simply learnt by the otolaryngologist familiar with fibre-optic laryngoscope usage. This method is also comfortable and convenient for the patient.
