EVALUATION OF ENDOSCOPIC SURGERY OUTCOMES FOR BENIGN VOCAL FOLD LESIONS AT MILITARY HOSPITAL 103

Objectives: To evaluate the endoscopic surgery outcomes for benign vocal fold lesions at Military Hospital 103. Methods: A prospective, case-by-case descriptive, clinical interventional study was conducted on 45 patients with benign vocal fold lesions who underwent endoscopic surgery at Military Hospital 103 from July 2022 to August 2023. Results: The disease is common among working-age adults whose ages range from 18 - 60 (77.8%); 100% of patients had hoarseness before surgery at all levels, of which moderate hoarseness accounted for 66.7%; 60.0% of patients had vocal fold nodules; the basic histopathological diagnosis was consistent with the clinical diagnosis. After the surgery, 82.2% of patients had no hoarseness. The average scores of voice handicap index (VHI) and VHI-10 decreased with statistical significance, p < 0.001; 80.0% of patients achieved very good results one month after surgery. Conclusion: Research results show the effectiveness of endoscopic surgery to treat benign vocal fold lesions. Both the VHI and VHI-10 scales are used to evaluate voice disorders, but in clinical practice, the VHI-10 scale may be used instead of the VHI scale.

Comparison and Relation Between Vocal Tract Discomfort and Voice Handicap Index in Teachers With and Without Muscle Tension Dysphonia

Objective One of the most voice-related complaints in teachers is vocal tract discomfort (VTD) which can increase the voice handicap index (VHI) to different degrees. In teachers Muscle Tension Dysphonia (MTD), increases voice complaints and decreases the voice-related quality of life. The aims of this study were to evaluate and compare the frequency and severity subscales of the VTD score and total score of VHI and determine the relation between them in primary school teachers with and without MTD. Materials & Methods This study was cross-sectional and was performed on 80 primary female teachers with and without MTD. The participants in both groups were randomly selected after checking the inclusion criteria. Voice history, auditory-perceptual assessment of voice, palpation, and laryngeal video-stroboscopy were assessed on the teachers in two groups. Then, asked the participants to complete the Persian versions of the VTD and VHI scales. After determining the normal distribution of the data using the Kolmogorov-Smirnov test, the results of VTD, VHI, and their subscales were compared between two groups with an independent t-test. Also, the relationship between them was assessed with the Pearson correlation coefficient analysis. Results The mean score of the frequency subscale of VTD in teachers with MTD was more than in teachers without MTD (30.17±5.11, 8.22±2.26), respectively. The score of severity subscales of VTD in teachers with MTD was 39.12±4.94 and in teachers without MTD was 7.89±2.13. Also, the total score of the VHI questionnaire in teachers with MTD was significantly higher than teachers without MTD (P<0.05). Moreover, there was a significant positive correlation between the frequency and severity subscales of VTD and the total score of VHI in the two groups (P<0.05). Conclusion This study showed the frequency and severity scores of the VTD and the degree of VHI experienced by MTD are remarkably higher than teachers without MTD. The authors emphasize on the use of VTD and VHI scales in screening teachers who are at risk of voice problems, and the researchers pointed out the importance of paying attention to the reduction of discomfort feelings in the vocal tract and voice handicap in the voice therapy sessions of teachers with MTD.

Voice-Related Quality of Life in Post-Laryngectomy Rehabilitation: Tracheoesophageal Fistula's Wellness.

(1) Introduction: Laryngeal cancer is one of the most common types of cancer affecting the upper aerodigestive tract. Despite ensuring good oncological outcome in many locoregionally advanced cases, total laryngectomy is associated with relevant physical and psychological sequelae. Treatment through tracheo-esophageal speech, if promising, can lead to very variable outcomes. Not all laryngectomee patients with vocal prosthesis benefit from the same level of rehabilitation mainly due to the development of prosthetic or fistula related problems. The relating sequelae in some cases are even more decisive in the patient quality of life, having a higher impact than communicational or verbal skills. (2) Material and Methods: A retrospective study was conducted on 63 patients initially enrolled with a history of total laryngectomy and voice rehabilitation, treated at the University Hospital of Catania from 1 January 2010 to 31 December 2018. Quality of life (QoL) evaluation through validated self-administrated questionnaires was performed. (3) Results: The Voice-Related Quality of Life questionnaire revealed significantly better outcomes in both socio-emotional and functional domains of the tracheoesophageal patient group compared to the esophageal group (p = 0.01; p = 0.01, respectively), whereas in the Voice Handicap Index assessment, statistically significant scores were not achieved (p = 0.33). (4) Discussion: The significant differences reported through the V-RQOL and Voice Handicap Index scales in the presence of fistula related problems and device lifetime reduction when compared to the oesophageal speech group have demonstrated, as supported by the literature, a crucial role in the rehabilitative prognosis. (5) Conclusions: The criteria of low resistance to airflow, optimal tracheoesophageal retention, prolonged device life, simple patient maintenance, and comfortable outpatient surgery are the reference standard for obtaining good QoL results, especially over time. Furthermore, the correct phenotyping of the patient based on the main outcomes achieved at clinical follow-up guarantees the primary objective of the identification of a better quality of life.

Relevant Work Factors Associated with Voice Disorders in Early Childhood Teachers: A Comparison between Kindergarten and Elementary School Teachers in Yancheng, China

Background: Early childhood teachers consist of kindergarten and elementary school teachers in the lower grades. Young children at school may increase the vocal load of these teachers. Therefore, the objectives of this study were to determine the prevalence of voice disorders and the associated factors in early childhood teachers, and to determine if differences exist between kindergarten and elementary school teachers. Method: A cross-sectional survey was performed in July 2019 as a network questionnaire. Through cluster sampling, teachers (n = 414) from all five public kindergartens (n = 211) in the urban area of Yancheng, China, and four public elementary schools (n = 203) in the same school district participated in this study. Multivariate logistic regression models were used to analyze the associations among the prevalence of voice disorders in the teachers, school type, and relevant factors. Results: Our results indicated, based on the Voice Handicap Index scale (VHI-10, China), that the prevalence of voice disorders in early childhood teachers was 59.7%, while that in elementary school teachers (65.5%) was significantly higher than that in kindergarten teachers (54.0%) during the previous semester. Contributing factors included daily class hours, classroom air humidity, and speaking loudly during teaching. Additionally, certain types of voice usage in teaching such as falsetto speak, speaking more than other teachers, not using vocal techniques, and habitual voice clearing, were significantly associated with voice disorders. Conclusion: Most early childhood teachers have voice disorders. Compared with the kindergarten teachers, the elementary school teachers experienced a significantly higher prevalence of voice disorders. Several factors among work organization, work environment, and types of voice usage in teaching were associated with the voice disorders in early childhood teachers. The finding suggests that voice training should be provided for early childhood teachers, classroom teaching time should be decreased, and the number of teachers in basic subjects should be increased in the lower grades of elementary schools.

Impact of education on quality of life of laryngectomized patients before and after vocal rehabilitation

<p>Introduction. Larynx carcinoma is one of the most common malignant tumors of the upper aerodigestive tract that causes the change in normal anatomical relationships in the neck, which leads to communication and social interaction disorders. The aim of the paper is to examine the impact of education on the quality of life of laryngectomized patients. Methods.The study included 50 laryngectomized patients, aged 51 to 83 years. The subjective voice assessment was carried out using the Voice Handicap Index (VHI) and the University of Michigan Head & Neck Quality of Life Instrument (HNQOL). The patients filled in the questionnaires before and after vocal rehabilitation. Results. The comparison of average scores of all examined laryngectomized patients before and after vocal rehabilitiation showed a statistically significant difference in the total score on VHI scale (107.20 ± 8.46 vs. 21.32 ± 13.29; p < 0.001), HNQO scale (52.50 ± 17.71 vs. 93.57 ± 6.36; p < 0.001), as well as on all subscales. Prior to vocal rehabilitation, there was no statistically significant difference between the scores on these two scales in patients with different level of education. After vocal rehabilitation, there was a statistically significant difference between the patients with secondary education and the ones with tertiary education in the scores on all VHI subscales, and total VHI score (23.60 ± 13.54 vs. 18.83 ± 11.59; p = 0.012), as well as in the scores for individual domains and the total score of HNQOL instrument (88.90 ± 6.58 vs. 99.80 ± 4.25; p = 0.048). Conclusion. Vocal rehabilitation after total laryngectomy had a positive effect on patients' quality of life, and patients with higher education showed a tendency towards better quality of life compared to the ones with lower education.</p>

Patient-Based Assessment of Effectiveness of Voice Therapy in Vocal Mass Lesions with Secondary Muscle Tension Dysphonia.

Use of patient-based voice assessment scales is an appropriate method that is frequently used to demonstrate effectiveness of voice therapy. This study was aimed at determining the effectiveness of voice therapy among patients with secondary muscle tension dysphonia (MTD) and vocal mass lesions. The study design was prospective, with within-participant repeated measures. Thirty-three patients with secondary MTD and vocal mass lesions participated in the study, selected on the basis of voice history, laryngeal palpation, and videostroboscopy examination. An experienced otolaryngologist and one experienced speech language pathologist undertook the diagnostic process. Voice therapy included both direct and indirect techniques and lasted approximately 2 months for all included patients. The voice handicap index (VHI) was used to evaluate the effectiveness of voice therapy among included patients. Paired t-test, size of the standardized effect (ESI), and mean standardized response (ESII) were used to analyze effectiveness of the target voice therapy. The findings of this study indicate a statistically significant improvement after the voice therapy protocol (P<0.05; t>1.96). Results of ESI and ESII demonstrate that the VHI scale is sufficiently responsive to detect voice therapy change (ES>0.8). This study recommends a combination of direct and indirect voice therapy in the vocal rehabilitation of patients with secondary MTD and vocal mass lesions. Furthormore, we recommend use of the VHI scale to show voice therapy changes for both clinical and research purposes.

Responsiveness of Persian Version of Consensus Auditory Perceptual Evaluation of Voice (CAPE-V), Persian Version of Voice Handicap Index (VHI), and Praat in Vocal Mass Lesions with Muscle Tension Dysphonia

This study was aimed at determining the internal and external responsiveness of the Persian version of the Consensus Auditory-Perceptual Evaluation of Voice (called ATSHA), Persian version of the Voice Handicap Index (VHI), and Praat scales among patients with vocal mass lesions and secondary muscle tension dysphonia. Prospective, within-participant repeated measures. Thirty patients with vocal fold nodules, polyps, and cysts related to secondary muscle tension dysphonia participated in the study. The measures of interest and videostroboscopy examination were used before and after treatment. The Global Perceived Effect questionnaire was used to separate those improved (moderately or greatly improved) and stable (slightly improved) patients. The mean standardized response, standardized effect size, and Guyatt analyses indicated high internal responsiveness for the all target parameters of the ATSHA, total score of the VHI, and two parameters of the Praat (0.8<). There was poor correlation between the videostroboscopy and the other target scales (r Pearson = -0.1-0.1). The receiver operating characteristic analysis indicated that all the target scales did not significantly separate those improved and stable subjects (area under the curve = 0), except for the overall severity and roughness parameters of the ATSHA scale (area under the curve = 1). This study recommends both the Consensus Auditory-Perceptual Evaluation of Voice and the VHI scales to show voice therapy changes. The target voice scale changes were not able to predict the videostroboscopy changes as external standard. Furthermore, we recommend that the overall severity and roughness may properly classify those improved and stable patients.

Multiparameter Voice Assessment for Voice Disorder Patients: A Correlation Analysis Between Objective and Subjective Parameters

The aim of this study was to establish a multiparameter voice assessment profile using objective multiparameter test and subjective voice quality assessment. We assessed 50 patients with voice disorders before and after operation. The assessment incorporates (1) subjective voice quality assessment, (2) patients' self-assessment, and (3) objective acoustic analysis. The subjective voice quality assessment uses GRABS system to evaluates the grade of hoarseness (G), proposed by the Japanese Society for Logopedics and Phoniatrics. Patients' self-assessment is modified based on the Chinese version of voice handicap index (VHI) scale, composed of functional (F), physiological (P), emotional (E) part, and a total score (T). The acoustical analysis evaluate the patients' voice sample by voice analysis software "Dr. Speech". Three parameters, jitter (J), shimmer(S), and normalized noise energy (NNE), were taken in analysis. We observed high correlations among subentries F, P, and the total score TvH of the VHI scale in patients' subjective assessment. Parameter E does not correlate well with other assessed parameters. The Chinese version ofVHI, which incorporate multifactors including age, education, and especially the cultural difference may account for the inconsistent correction in parameter E. In the objective acoustic analysis, high correlation among the three parameters J, S, and NNE is observed. Systemic assessment combining a subjective voice quality assessment, an objective acoustic analysis, and a self-assessment is helpful in clinical practice in the diagnosis and treatment for voice disorders. The E component in VHI scale assessment may not be a reliable parameter to evaluate treatment outcome.

Graduierung des Voice-Handicap-Index

The Voice Handicap Index (VHI) questionnaire is currently regarded as the gold standard for the measurement of subjective suffering caused by dysphonia. The object of this study was to show how to weight or grade the result yielded by the VHI. To this end, the result obtained with the VHI was graded against the external criterion of health-related quality of life and also compared with the VHI results obtained in persons not affected by dysphonia. A total of 101 patients (61 women, 40 men) aged between 19 and 86 (48.4 +/- 14.6) years and suffering from benign dysphonia (organic in 62%, functional in 38%: 62% and 38%, respectively in the women, 63% and 37%, respectively, in the men) took part in the study. The instruments used were a German version of the VHI and the SF-36 Health Survey on health-related quality of life, which is commercially available. There are two subscales to the SF-36, but only the values for physical health were significantly reduced and correlated significantly with the results on the VHI scale. This subscale was therefore used as the external standard for grading of the VHI results. Following the separation of the VHI results recorded in the nondysphonic test subjects a four-point grading of the VHI results emerged. VHI values of 0-11 are classified as grade 0 suffering (almost certainly not noticeable), while values of 12-28 reflect grade 1 (more likely unnoticeable than conspicuous) suffering; values of 29-56 reflect grade 2 suffering (more probably noticeable than not), and values of 57-120 suggest a classification of certainly noticeable and are graded as grade 3 suffering.

Evaluation of Voice Acoustic Parameters Related to the Vocal-Loading Test in Professionally Active Teachers with Dysphonia

Teachers are at risk of developing voice disorders. A clinical battery of vocal function tests should include non-invasive and accurate measurements. The quantitative methods (e.g., voice acoustic analysis) make it possible to objectively evaluate voice efficiency and outcomes of dysphonia treatment. To identify possible signs of vocal fatigue, acoustic waveform perturbations during sustained phonation were measured before and after the vocal-loading test in 51 professionally active female teachers with functional voice disorders, using IRIS software. All the participants were also subjected to laryngological/phoniatric examination involving videostroboscopy combined with self-estimation by voice handicap index (VHI)-based scale. The phoniatric examination revealed glottal insufficiency with bowed vocal folds in 35.2%, soft vocal nodules in 31.4%, and hyperfunctional dysphonia with a tendency towards vestibular phonation in 19.6% of the patients. In the VHI scale, 66% of the female teachers estimated their own voice problems as moderate disability. An acoustic analysis performed after the vocal-loading test showed an increased rate of abnormal frequency perturbation parameters (pitch perturbation quotient (Jitter), relative average perturbation (RAP), and pitch period perturbation quotient (PPQ)) compared to the pre-test outcomes. The same was true of pitch-intensity contour of vowel /a:/, an indication of voice instability during sustained phonation. The recorded impairments of voice acoustic parameters related to vocal loading provide further evidence of dysphonia. The voice acoustic analysis performed before and after the vocal-loading test can significantly contribute to objective voice examinations useful in diagnosis of dysphonia among teachers.
