Laryngeal Tuberculosis

AbstractObjectives:To evaluate the effects of antituberculosis treatment on the voice quality of laryngeal tuberculosis patients, measured by patient self-assessment, perceptual analysis and acoustic analysis.Materials and methods:A total of 14 laryngeal tuberculosis patients were enrolled. Laryngeal tuberculosis was established either by biopsy and histopathological examination or by rapid regression of the laryngeal lesions after antituberculosis medication. Before and after treatment, all patients were evaluated perceptually (on a scale of zero to three), and 12 assessed their own voices using the voice handicap index-10 scale. Acoustic analysis was performed to allow objective evaluation.Results:Patients' ages ranged from 21 to 72 years (mean, 41). The male to female ratio was 12:2. Eight patients (57 per cent) had tuberculous involvement of the epiglottis, four (28 per cent) had involvement of the aryepiglottic fold and eight (57 per cent) had involvement of the false vocal folds. The glottis was the less commonly involved part of the larynx, including true vocal folds (28 per cent, n = 4) and posterior commissure (14 per cent, n = 2). Perceptual evaluation, on a scale of zero to three, gave the patients a median score of six; after commencement of treatment, the median score decreased to two. The mean voice handicap index-10 score decreased from 24 to 12 after treatment. An obvious improvement in acoustic analytical parameters was also found following treatment.Conclusions:Antituberculosis treatment clearly improved the voice outcomes of laryngeal tuberculosis patients, according to self-assessment, perceptual analysis and acoustic analysis.

PURPOSE: To compare the vocal self-perception and vocal complaints reported by two groups of students of the pedagogy course (freshmen and graduates); to relate the vocal self-perception to the vocal complaints for these groups; and to compare the voice quality of the students from these groups through perceptual auditory assessment and acoustic analysis. METHODS: Initially, 89 students from the pedagogy course answered a questionnaire about self-perceived voice quality and vocal complaints. In a second phase, auditory-perceptual evaluation and acoustic analyses of 48 participants were made through voice recordings of sustained vowel emission and poem reading. RESULTS: The most reported vocal complaints were fatigue while using the voice, sore throat, effort to speak, irritation or burning in the throat, hoarseness, tightness in the neck, and variations of voice throughout the day. There was a higher occurrence of complaints from graduates than from freshmen, with significant differences for four of the nine complaints. It was also possible to observe the relationship between vocal self-perception and complaints reported by these students. No significant differences were observed in the results of auditory-perceptual evaluation; however, some graduates had their voices evaluated with higher severity of deviation of normalcy. During acoustic analysis no difference was observed between groups. CONCLUSION: The increase in vocal demand by the graduates may have caused the greatest number and diversity of vocal complaints, and several of them are related to the self-assessment of voice quality. The auditory-perceptual evaluation and acoustic analysis showed no deviations in their voice.

Purpose: To analyze the effectiveness of a physiological vocal warm-up program focused on religious singers. Method: longitudinal study involving 39 subjects male and female, aged at least 18 and at most 50, the participants underwent an evaluation vocal pre-warm-up and vocal post-warm-up, results being compared to both evaluations. The evaluation was applied questionnaire vocal habits and symptoms, acoustic analysis and auditory perceptual analysis. The study was conducted in Catholic Churches of Várzea Grande City in the state Mato Grosso. Results: They said participants to use the corner of a median of 87.3 months with weekly frequency of 2.4 times per week. However, 89.7% of the singers reported not warm up the voice before the corner and not desaquecerem 94.9% after the corner. In inadequate vocal habits most said talking aplenty. Already in vocal symptoms the three most prevalent were: voice worse in the morning (59.0%), loss of treble (54.4%) and hoarseness constant (51.3%). After application of vocal warm-up program improvement was observed in vocal self assessment and auditory perceptual analysis. There was also a significant increase in the fundamental frequency of the sustained vowel, but for the singing voice there was no change in acoustic parameters analyzed. Conclusion: The vocal heating program was effective with positive changes in voice adjustments, providing a more comfortable voice output this being noticed by singers themselves.

This prospective study assessed the advantages and problems associated with converting a patient using an older generation non-indwelling voice prosthesis to a newer generation indwelling voice prosthesis, in this case the Provox®2. The voice characteristics of each patient were measured using the old and then the new voice prosthesis. Technical aspects of the insertion of the indwelling prosthesis were noted. Each patient completed a questionnaire after a period of use with the indwelling prosthesis.Changing the prosthesis was simple and uncomplicated in 15 of 17 patients. Acoustic analysis showed improved parameters with the indwelling prosthesis, but no perceptual difference between the two prostheses. The questionnaire revealed that most patients preferred the indwelling prosthesis.Replacing a non-indwelling with an indwelling prosthesis is technically simple, leading to improvement in voice quality and patient satisfaction. It may be reasonable to offer this choice to patients currently using an older generation non-indwelling voice prosthesis.

Abstract Background Voice alterations after thyroidectomy with mobile vocal folds are common. Ultrasonography has been used to assess the mobility of the vocal folds after thyroidectomy. Methods 54 patients underwent thyroidectomy. Indirect laryngoscopy, ultrasonography and GRBAS scoring were performed preoperatively,3 days, 2 and 6 months postoperatively. Results On the third postoperative day, the mobility of the vocal folds was preserved in 52 patients and paresis were recorded in 2 patients. All patients after total thyroidectomy noted the presence of voice alteration in the absence of the postoperative paresis of the vocal folds. On the third postoperative day, the voice was impaired by all criteria of the GRBAS scale, but mainly due to roughness (85%). Sixth month postoperatively 62% of the subjects considered the voice to be altered. Asthenia was observed in 39%. On the third postoperative day indirect laryngoscopy revealed the unchanged vocal folds, the symmetrical edema and the shortening of one of the vocal folds in 56%,42% and 1.9%. Six months postoperatively, the vocal folds returned to their original form. Ultrasonography was well correlated to the results of indirect laryngoscopy. Patients with edema of the vocal folds had a significantly higher mean GRBAS grade than patients without edema. The mean GRBAS score decreased from 3.36 to 0.90, 3 days and 6 months postoperatively. Conclusion Voice alteration after total thyroidectomy is always present. Postoperative edema represents a likely main cause of voice alteration and resolves within 6 months. Ultrasonography is recommended as alternative to indirect laryngoscopy in assessing of the vocal folds in thyroid surgery patients.

Aim of study: Evaluation of the speech therapy on voice quality in patients with unilateral vocal fold palsy. Material and methods: The study group included 11 patients, 8 women and 3 men, in age between 16 to 72 years, with unilateral vocal fold palsy, diagnosed in ENT Department of Warsaw Medical University between 2017-2018. Each person completed questionnaires: the voice disability self-assessment scale (VHI), the voice-based quality of life (VRQoL) scale, the vocal tract discomfort scale (VTD). All questionnaires were completed twice, before and after the voice therapy. In addition, the acoustic analysis of the voice, the assessment of the maximum phonation time and the breathing tract were performed twice in each patient. Each of the patients had a voice rehabilitation consisting of a series of 10 meetings. Results: Statistical analysis of the results of maximum phonation time, the self-assessment of voice disability, the quality of life depending on the voice, discomfort of the vocal tract voice acoustic analysis showed statistically significant differences in the results before and after rehabilitation (p <0.005). In addition, the improvement of the respiratory tract was observed in the majority of patients. Conclusions: Speech therapy significantly affects the voice quality of patients with unilateral laryngeal nerve palsy.

OBJECTIVE: To evaluate the voice quality of patients with idiopathic Parkinson's disease, at the "on" and "off" moments of the disease. METHOD: Five individuals with Parkinson's disease and five of the control group were assessed. All of them underwent the recording of voice and speech. The acoustic parameters analyzed were: fundamental frequency, jitter, shimmer, harmonic noise proportion and index of tremor, besides performing the hearing-perceptual analysis by means of GRBASI scale. The findings were analyzed using statistics through t test and the level of significance adopted was p<0.05. RESULTS: There was no difference in the acoustic parameters in the three analyzed groups. In the hearing-perceptual analysis, patients with idiopathic Parkinson's disease showed altered voice quality and the ones from the control group, neutral vocal quality. CONCLUSION: Patients with idiopathic Parkinson's disease present rough, breathy and unstable vocal quality in both stages. In the acoustic analysis, there are no differences in the studied parameters.

AbstractObjective:To investigate perceptual, acoustic and aerodynamic voice parameters in obese individuals.Methods:Twenty obese and 20 normal-weight volunteers underwent voice evaluation by laryngoscopy, acoustic analysis, aerodynamic measurement and perceptual analysis (using the grade-roughness-breathiness-asthenia-strain (‘GRBAS') scale and the Voice Handicap Index 10 scale). Data from both subject groups were compared.Results:No difference was found in acoustic analysis parameters between the two groups (p > 0.05). Maximum phonation time in the obese group (mean ± standard deviation, 19.6 ± 4.9 seconds) was significantly shorter than in controls (26.4 ± 4.1 seconds) (p < 0.001), although the s/z ratio was very similar between the two groups. In the obese and control groups, the mean ± standard deviation grade-roughness-breathiness-asthenia-strain scores were 1 ± 1.3 and 0.2 ± 0.6 (p = 0.002) and the mean ± standard deviation Voice Handicap Index 10 scores were 0.5 ± 1.2 and 1.2 ± 1.7 (p = 0.27), respectively.Conclusion:Obese individuals had poorer vocal quality as judged by the grade-roughness-breathiness-asthenia-strain scale, and reduced maximum phonation time. However, there was no change in voice quality as assessed by acoustic analysis and Vocal Handicap Index 10 score, compared with controls.

The voices of 42 students studying classical opera singing at the Estonian Academy of Music were investigated to find any objectively definable qualities possibly correlating with the length of training. Each student's singing of a four-bar seven-word initial phrase from a well-known Estonian classical solo was recorded. The recordings were digitalized and subjected to acoustic analysis yielding the long-term average spectrum (LTAS) for each voice studied. It turned out that the longer a singing student had been trained professionally, the higher was the level of the so-called singer's formant in her/his LTAS. Subsequently the voice quality in each recording was evaluated by four experts using a five-point scale, five points marking the best quality and one point the poorest. It turned out that the average ratings did not show any positive correlation with the length of training, rather, a slightly negative trend (notstatistically significant) could be observed. The results seem to support the critical remarksmade bysome Estonian specialists about domestic teaching of vocal music being perhaps inadequate in some respects (Pappel, 1990). The teaching process seems to be focused on the development of those qualities that enable the singer to be audible in large halls and with a symphony orchestra, while the timbral qualities recede into the background.

Background Voice problems caused by pathologies in vocal folds are well known. Some types of laryngeal pathologies have certain acoustic characteristics. Objective evaluation helps characterize the voice and voice problems providing supporting evidences, severity of disorders. It helps assess the response to the treatment and measures the outcomes.Objective The objective of the study is to determine the effectiveness of the voice therapy and quantify the results objectively by voice parameters.Method Study includes 61 patients who presented with different types of laryngeal pathologies. Acoustic analyses and voice assessment was done with Dr. Speech ver 4 (Tiger DRS Inc.). Acoustic parameters including fundamental frequency, jitters, shimmers, Harmonic to noise ratio (HNR), Normalized noise energy (NNE) were analyzed before and after voice therapy.Result Bilateral vocal nodules were the most common pathologies comprising 44.26%. All acoustic parameters showed a significant difference after the therapy (p<0.05) except for NNE. Dysphonia due to vocal fold polyp showed no improvement even after voice therapy (p>0.05).Conclusion Acoustic analysis provides an objective, recordable data regarding the voice parameters and its pathologies. Though, few pathology require alternative therapy rather than voice therapy, overall it has a good effect on glottic closure. As the voice therapy can improve the different indices of voice, it can be viewed as imperative part of treatment and to monitor progression.
