Paediatric vocal fold nodules: management strategies to restore normal phonation-Speech-Language Pathologists perspective: A cross-sectional survey.

Vocal fold nodules are benign vocal cord lesions which develop in voice abusers, including children, though chronic cough, sinusitis, and reflux may also be the causative agents. Since low or no-evidence treatment strategies, like the boone technique, are in use in paediatrics, this study was conducted to determine the treatment strategies used by speech-language pathologists in paediatric vocal fold nodules using a cross-sectional survey at Riphah International University, Lahore, from October 2016 to May 2017. Sixty-five speech-language pathologists working with children in private clinics and multidisciplinary settings were recruited using purposive sampling. A self-structured questionnaire was used for data collection. Analysis using SPSS -18 revealed that a combination of voice therapy and vocal hygiene was the most favoured treatment used by 65 (100%) speech-language pathologists, followed by 58 (89.2%) who also favoured respiratory and relaxation exercises, and 56 (86.2%) who also included parental counselling. Hence, a combination of voice therapy and vocal hygiene is a good therapeutic technique being practiced by speech pathologists for the treatment of vocal nodules among paediatric population.

Personality traits inventory in patients with vocal nodules.

The objective of the study was to analyze temperament and character in females with vocal nodules (VN) compared to a vocally healthy control population. 61 females were examined over a 17-month period for dysphonia with VN (mean age 46 years, duration of vocal complaints from 2 months to 6 years). 71 control females were recruited in their environment (mean age 34 years). The validated French Version of the Temperament and Character Inventory (TCI) was used. Patients with VN had significantly (p < 0,05) greater scores for Persistence and Novelty Seeking, particularly for the subscales exploratory excitability and extravagance. They had lower scores for Harm Avoidance, in particular fear of uncertainty, shyness and fatigability. Scores on Reward Dependence were not significantly different except for the subscale dependence, which were significantly lower in patients. No significant difference was found with regard to scores on Self-directedness, except for scores on the subscale self-acceptance, which were significantly lower in patients. Scores on Cooperativeness were not significantly different, except for the subscale helpfulness, which were significantly higher in patients. Patients had significant greater scores for Self-transcendence overall and specifically on the subscales self-forgetfulness and spiritual acceptance. Our findings suggested that women with VN are likely to have a passionate temperament, which might constitute an indirect predisposition to elevated vocal loading and greater risk for phonotrauma. The risk for developing or maintaining VN could be decreased by attending to those personality-specific maladaptive behaviors. A possible personalized approach to voice therapy could be organized on the basis of the TCI findings.

Voice treatment of school-aged children with vocal nodules with ABCLOVE rehabilitation.

BACKGROUND: This study was to explore the effectiveness of the ABCLOVE exercise on school-aged children with vocal nodules after the treatment of budesonide. METHODS: Eighty-six school-aged children with vocal nodules were divided into control and ABCLOVE therapy groups. Subjective voice assessment and dysphonia severity index (DSI) assessment were performed before and after the 3-month of therapy. RESULTS: A significant improvement was observed in the ABCLOVE therapy group as compared with the control group (p = 0.035). ABCLOVE therapy significantly reduced the hoarseness and roughness scores in school-aged children with vocal nodules. Additionally, a significant reduction in functional score, physical score, emotional score, and total pVHI score was observed in the ABCLOVE therapy group. Moreover, acoustic parameters including jitter (%) and shimmer (%) were significantly reduced, whereas MPT and DSI were increased in school-aged children with vocal nodules who received 3 months of ABCLOVE treatment. CONCLUSION: ABCLOVE therapy displayed effectiveness on school-aged children with vocal nodules after the treatment of budesonide.

Psychological Distress in a Sample of Adult Italian Patients Affected by Vocal Nodules and Muscle-Tension Dysphonia: Preliminary Results.

OBJECTIVES: To evaluate the correlation between voice disorders and psychological distress, in terms of anxiety, stress, and depression, in a sample of adult Italian patients and to compare our results with those obtained in a group of adult healthy controls matched by age, sex, geographic distribution, and occupation. METHODS: This prospective-controlled study included 100 adults with Vocal nodules (VN) and Muscle Tension Dysphonia (MTD1), aged between 18 and 65 years, as Experimental Group (EG) and 100 age-matched subjects without any voice disorders as a Control Group (CG). All patients in the EG underwent a phoniatric evaluation, including the administration of the Voice Handicap Index (VHI) and laryngeal examination. Both patients of EG and CG underwent a Psychological evaluation by means of standardized tests; Beck's Depression Inventory, State Anxiety Inventory (STAI 1-State Anxiety), Trait Anxiety Inventory (STAI 2- Trait Anxiety), and Perceived Stress Scale (PSS-10) were completed by patients. Fisher's exact test and chi-squared test were used to compare all categorical variables, whereas numerical variables were compared either with the nonparametric Mann-Whitney-Wilcoxon or with Kruskal Wallis test. General linear models were used to study continuous variables between patients and controls and between different groups within the sample. RESULTS: In the study group, the Physical domain (P score) of the VHI was more affected than the Emotional (E score) and Functional ones (F score) both in patients with MTD1 and VN; patients with VN presented a significant difference in P score, E score and VHI total score than patients with isolated MTD 1 (P < 0.005). Psychological assessment showed a significant difference (P < 0.005) between VN and MTD 1 regarding PSS-10 and STAI-1 scores. Low Beck's Depression Inventory scores were present in our sample without significant differences between patients with VN and those with MTD 1. Scores related to psychological distress in the EG were far superior to those obtained by the healthy CG, with markedly significant values especially for PSS-10 (P < 0.0001) and STAI 2 (P < 0.01). Finally, younger patients (18-35 years) with VN showed a highest risk of psychosocial distress. CONCLUSION: the present study identified a high prevalence of psychological distress among patients with vocal disorders without any prior specific psychiatric diagnosis, especially in terms of anxiety and perceived stress. For this reason both these symptoms should be taken into consideration in the diagnostic, therapeutic, and follow-up process of patients with MTD1 and VN.

A General Survey of Pharynlaryngeal Diseases and Voice Disorders Among Basic Education Teachers in Tianjin.

OBJECTIVE: In this study, we created a city-wide database of pharynlaryngeal diseases and voice disorders among basic education teachers to analyze the incidence, distribution, and risk factors of pharynlaryngeal diseases and voice disorders. METHODS: A total of 47,823 teachers in primary and secondary schools and kindergartens of Tianjin were enrolled in this study and underwent questionnaires and throat examinations. In addition, the data were subjected to descriptive statistics, chi-square analysis, and univariate and multivariate logistic regression analyses. RESULTS: Pharynlaryngeal diseases and voice disorders had an overall prevalence of 69.42% among basic education teachers in Tianjin, wherein the prevalence of chronic pharyngitis, chronic hyperplastic laryngitis, and chronic simple laryngitis were the highest at 39.45%, 19.80%, and 15.59%, respectively. The results of multivariate logistic regression analysis suggest that pharynlaryngeal diseases and voice disorders were statistically correlated with gender (P < 0.001), years of teaching (P < 0.001), school district (P < 0.001), class size (P < 0.001), subjective assessment of teachers on vocal loudness (P < 0.001), neck and shoulder discomfort (P < 0.001), smoking (P < 0.001), psychological stress (P = 0.002), and frequent habitual throat clearing (P < 0.001). Furthermore, the risk factors for pharynlaryngeal diseases and voice disorders were age (P = 0.002), school district (P < 0.001), class size (P = 0.008), neck and shoulder discomfort (P = 0.038), smoking (P < 0.001), water intake habits during class (P = 0.023), and frequent habitual throat clearing (P = 0.001) for male teachers, and for female teachers, it was age (P < 0.001), school district (P < 0.001), daily teaching hours (P = 0.005), class size (P < 0.001), subjective assessment of teachers on vocal loudness (P < 0.001), neck and shoulder discomfort (P < 0.001), smoking (P = 0.033), psychological stress (P = 0.003), and frequent habitual throat clearing (P < 0.001). CONCLUSION: Due to the high prevalence of pharynlaryngeal diseases and voice disorders among basic education teachers, throat and voice health education-related activities should be conducted for teachers to intervene in the occurrence of pharynlaryngeal diseases and voice disorders at an early stage.

Auditory-Motor Function Pre- and Post-Therapy in Hyperfunctional Voice Disorders: A Case Series.

OBJECTIVE/HYPOTHESIS: Behavioral voice therapy is the most common treatment for hyperfunctional voice disorders (HVDs) but has limited long-term effectiveness since the comprehensive mechanisms underlying HVDs remain unclear. Recent work has implicated disordered sensorimotor integration during speech in some speakers with HVDs and suggests that auditory processing is a key factor to consider in HVD assessment and therapy. The purpose of this case-series study was to assess whether current voice therapy approaches for HVDs resulted in improvements to auditory-motor function. STUDY DESIGN: Longitudinal (pre-post) study. METHOD: Pre and postvoice therapy for HVDs, 11 speakers underwent an assessment of auditory-motor function via auditory discrimination of vocal pitch, responses to unanticipated auditory perturbations, and responses to predictable auditory perturbations of vocal pitch. RESULTS: At the post-therapy session, 10 out of 11 participants demonstrated voice therapy success (via self-reported voice problems and/or auditory-perceptual judgements of voice by a clinician) and eight of the 11 participants demonstrated improvements in at least one measure of auditory discrimination and/or auditory-motor control. Specifically, three speakers demonstrated improvements in auditory discrimination, five speakers demonstrated improved (within typical cutoffs) responses to predictable perturbations, and two speakers demonstrated improvements in both auditory discrimination and auditory-motor measures. CONCLUSIONS: Together, these findings support that voice therapy in individuals with HVDs may impact auditory-motor control and highlight the potential benefit of systematically addressing auditory function in voice therapy and assessment for HVDs.

The effect of sound field amplification systems on vocal demand response in teachers during lessons.

PURPOSE: Sound pressure level (SPL), fundamental frequency (F0), time dose (Dt), cycle dose (Dc), and distance dose (Dd) are components affecting a vocal demand response. The study aimed to investigate the impact of sound field amplification systems (SFAS) on teachers' vocal parameters and determine the user comfort of SFAS use in teachers. METHODS: Twenty female teachers underwent long-term voice dosimetry with Vocal Holter Med (PR.O.Voice Srl) during everyday teaching activities. The SFAS PentaClassRuna (Certes) was installed in classrooms. Voice dosimetry was provided in two different acoustical conditions-without the use of SFAS (one to two days) and with SFAS (one to three days). Teachers underwent voice acoustic and laryngoscopic evaluation before voice dosimetry. Two teachers' groups were formed: teachers with and without vocal nodules. The visual analogue scale measured the user comfort of SFAS. RESULTS: There were no significant differences in vocal parameters and vocal doses between teachers with and without vocal nodules. Voice amplification significantly decreased average F0(-4.4 Hz), Dt%(-3.1%), Dc (-0.4 kcycles), and Dd (-1.3 m) in teachers without vocal nodules and F0 (-8.9 Hz) in teachers with vocal nodules. Vocal doses (Dt%, Dc, Dd) significantly decreased in classrooms with longer reverberation time. The user comfort of the SFAS during the lessons was high in both teachers groups. CONCLUSIONS: SFAS was a mediator between the classroom's environment and the teacher's vocal demand response; it changed teachers' voice production parameters and reduced vocal demand response to satisfy the communication requirements. In addition, voice amplification was more beneficial for teachers without vocal fold lesions.

Vocal nodules in children: Laryngoscopic morphological classification aids prognostic judgment.

Objective: Vocal fold nodules (VFNs) are benign lesions, occurring at the junction of the anterior and middle thirds of bilateral vocal cords, for which pediatric prognosis and treatment remains controversial. There is a requirement for a correlation indicator to assess the prognosis by pediatric otolaryngologists. Materials and methods: Patients with VFNs, who were admitted to the department of otolaryngology, were enrolled. The patient's gender, age, duration of dysphonia, laryngoscopy results and related diseases [allergic rhinitis, sinusitis, laryngopharyngeal reflux (LPR)] were collected and recovery from dysphonia followed up. Correlations between clinical factors and type of laryngoscopic morphology of VFNs were analyzed. Results: A total of 432 patients with dysphonia were identified, 208 agreed to undergo laryngoscopy and 194 were diagnosed with VFNs as a result. The modal age of patients with dysphonia was between 3 and 7 years with a male: female ratio of 2.1:1 (294:138) and 116 (26.85%; 116/432) had symptoms of allergic rhinitis. The boy to girl ratio among the 194 children with VFNs was about 2.6:1 (140:54) and modal age was consistent with dysphonia. Vocal nodules were the cause of most phonation disorders (93.27%; 194/208) and those with long duration of dysphonia presented more mature (p = 0.026) and discrete types (p = 0.022). Boys were more likely to have mature (p = 0.050) and discrete nodules (p = 0.008). Dysphonia recovery time was closely related to age (p = 0.000), duration of dysphonia (p = 0.000) and morphology of vocal nodules under laryngoscopy (p = 0.000). Conclusion: Vocal nodules are the most frequent cause of phonation disorders in children. The morphological classification by endoscopy may help with clinical diagnosis and therapy choice. In the case of the older child with longer duration of dysphonia and the appearance of mature, large, discrete nodules by laryngoscopy, active treatment is recommended, such as drug therapy, voice therapy or surgical treatment.

Emotional Adjustment in Children with Vocal Fold Nodules.

INTRODUCTION: Vocal fold nodules (VNs) in children are benign, bilateral, callous-like lesions at the junction of the anterior third and posterior two-thirds of the true vocal folds. Chronic, repetitive, and intense vocal behavior is often cited as the primary etiology; however, difficulties with emotional adjustment may predispose some children towards extreme and possibly phonotraumatic vocal activity, thereby contributing secondarily to the development of VNs. OBJECTIVES: This case-control study examined the association between features of emotional adjustment and VNs in children. METHODS: Parents of children with VNs (N = 40, Mage = 7.5, SDage = 2.03) and two medical control groups [ie, voice disordered, but not VNs (VDCs; N = 40, Mage= 7.09, SDage = 2.01) and vocally normal controls (VNCs; N = 40, Mage = 7.6, SDage = 1.54)] participated in the study. Features of emotional adjustment were assessed using two inventories: the Parent Rating scale for Reactive and Proactive Aggression and the Revised Child Anxiety and Depression Scale - Parent version. RESULTS: As compared with the VNCs, children with VNs were significantly more aggressive (P = 0.042, Cohen's d = 0.47) whereas the VDCs were more depressed (P = 0.013, Cohen's d = 0.60). Furthermore, VDCs experienced more separation anxiety than VNs (P = 0.038, Cohen's d = 0.45) and VNCs (P = 0.021, Cohen's d = 0.55). No other significant between-group differences were identified between the VNs and VDCs. CONCLUSIONS: When present, elevated aggression may represent a risk factor for VNs formation in children, and possibly influence treatment outcomes. Therefore, the current results highlight the importance of understanding the role of emotional adjustment in the evaluation and treatment of dysphonia in children.

Impact of Voice Therapy on Pediatric Patients With Dysphonia and Vocal Nodules: A Systematic Review.

One of the most prevalent pediatric ailments around the world is voice disorders. Around 5-million children suffer from voice disorders, and three out of five of them suffer from vocal nodule-induced persistent dysphonia. Nineteen out of 20 otolaryngologists recommend voice therapies for the treatment of pediatric vocal fold nodules. However, the benefits of these therapies still remain to be assessed systematically. The objective of this study is to systematically review the impact of voice therapy (direct and indirect) on pediatric patients with vocal nodules. In this systematic review of randomized control trials (RCTs), four electronic databases, PubMed, CENTRAL (Cochrane), Science Direct, and Lancet, were explored for the literature survey. The impact of direct and indirect voice therapies on pediatric cases with vocal nodules was reviewed based on the results of the selected articles. Based on stringent inclusion and exclusion criteria, six articles were selected. All these studies examined the effects of direct and indirect voice therapies on two types of voice disorders, that is, dysphonia and vocal nodules. Only one of the six studies reported significant alleviation of the patient condition post-intervention. However, none of the studies discussed the clinical significance of the interventions. Three of the six included studies used both direct and indirect voice therapies and reported substantial differences in the data collected before and after the interventions. However, overall, the studies reported more significant improvements in patient conditions. More studies in this domain are still warranted, especially to help understand and define the meaning of the term "effectiveness" with respect to voice therapies.

Voice Disorders in Children: Experience in the Voice Unit at Universidad Católica Clinical Hospital.

INTRODUCTION: Dysphonia in children is a common symptom, its prevalence varies between 6% and 23%. There is a broad differential diagnosis and the recommendation is to evaluate dysphonic children with an adequate laryngeal visualization method to achieve an accurate diagnosis and treatment. OBJECTIVE: To describe the experience in the diagnosis of dysphonia in children in the voice unit at Universidad Católica Clinical Hospital Santiago, Chile. METHODS AND MATERIALS: A retrospective chart review was conducted of all new pediatric patients treated in the voice unit at Universidad Católica Clinical Hospital between 2012 and 2019. Demographic data, diagnosis, and in-office laryngoscopies were reviewed. All patients were evaluated by the same work team consisting of two Otolaryngologists specialized in vocal pathology and a speech voice therapist. RESULTS: A total of 126 new pediatric patients between the ages of 0 to 18 years were evaluated in the voice unit at Universidad Católica Clinical Hospital Santiago, Chile. The majority were males (54%) with an average age of 9 years. 40% of the diagnosis corresponded to vocal nodules, 26% to vocal cord cysts, the remaining to a group of less frequent diagnosis. Two different groups were studied, the first group evaluated during the years 2012-2015 with flexible fibre-optic laryngoscopy and rigid videolaryngostroboscopy (VLS); the second group evaluated between the years 2015-2019 with distal chip flexible videolaryngoscopy, distal chip flexible VLS and rigid VLS. In the second group, the diagnosis of vocal nodules decreased, and the diagnosis of vocal cord cysts increased in comparison to the first group. CONCLUSION: Pediatric patients with dysphonia must be evaluated by a multidisciplinary team of experts and adequate equipment. VLS should be considered the gold standard in the diagnosis of vocal cord pathology in pediatric population.

Acoustic, Perceptual, and Laryngoscopic Changes Post Vocal Abuse at a College Fest.

INTRODUCTION: College students use their voices at excessively loud intensities and long durations during college fests. The accumulative effect of vocally abusive behaviors in the presence of high ambient noise, poor vocal hygiene, and other environmental factors contribute significantly towards reducing vocal effectiveness in college students. OBJECTIVE: The present study aimed to study the effect of a vocally demanding situation (college Fest) on perceptual and objective voice features of college students. METHODOLOGY: In this study, a total number of 27 undergraduate female students participated in the age range of 18-27 years. Pre-test-post-test research design was applied. Data analysis consisted of video stroboscopic examination, acoustic analysis using the Multi-dimensional voice program (MDVP), and perceptual evaluation with the GRBAS scale. The data obtained were processed using descriptive statistics and non-parametric tests to determine the difference in each measured parameter pre- and postfest. RESULTS AND DISCUSSION: Incomplete glottis closure, asymmetric vibration of vocal folds, and aperiodicity of vocal folds increased significantly postcollege Fest. GRBAS parameters also showed a change from pre Fest scores on grade (hoarseness) increased by 38%, breathiness in 34%, roughness in 26%, Asthenia in 15%, and strain increased in 38% participants. A P-value estimation revealed significantly higher scores in Jitter percent, Shimmer percent, and relative average perturbation than pre-fest scores. CONCLUSION: The results of the present study indicate a high risk of vocal disorders among college students post Fest. This study suggests a potential unmet need for college students to receive education before cultural events on optimal vocal usage, vocal hygiene, and an appropriate period of vocal rest.

Self-regulation in children with vocal fold nodules: A multilevel analysis.

INTRODUCTION: Vocal fold nodules (VNs) represent the most common cause of voice disorders in children. Phonotrauma related to chronic, repetitive, intense vocal activity is often cited as the proximate cause of VNs. However, diminished self-regulation (SR) may predispose some children toward extreme phonotraumatic voice use, thereby contributing secondarily to their development. This case-control study examined the association between features of SR and VNs in children. METHOD: Parents of children with VNs (N = 40, Age Mean = 7.5, SD = 2.03 years) and vocally normal, medical controls (VNCs; N = 40, Age Mean = 7.6, SD = 1.54 years) completed the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2; Gioia, Isquith, Guy & Kenworthy, 2015), an inventory that evaluates components of SR in children. RESULTS: Children with VNs, as compared with the vocally normal control group, were described as (i) impulsive (i.e., scoring significantly worse on the Behavior Regulation Index, BRI; P < 0.001, Cohen's d = 0.86), and (ii) emotionally dysregulated (i.e., scoring significantly worse on the Emotional Regulation Index, ERI; P < 0.001, Cohen's d = 0.81). CONCLUSIONS: Diminished SR in some children with VNs may contribute to phonotraumatic vocal behaviors and potentially attenuate the effectiveness of voice therapy.

The Effectiveness of Vocal Hygiene Education With Resonant Voice Therapy for School-Aged Children With Vocal Nodules.

OBJECTIVE: This study evaluated the effectiveness of vocal hygiene education with resonant voice therapy for school-aged children with vocal nodules. STUDY DESIGN: A pre-test/post-test control group design was employed. METHODS: Seventeen children aged between 6 and 9 years old with vocal nodules were randomly assigned to three groups: a treatment group, a placebo group and a control group. Children in the treatment group (n = 7) received six consecutive, weekly, one-hour sessions of vocal hygiene education with resonant voice therapy. Children in the placebo group (n = 5) received six consecutive, weekly, one-hour sessions on presentation skills training. Children in the control group (n = 5) did not receive any form of treatment. Subjective outcome measures included auditory-perceptual evaluation of overall dysphonia severity, the Pediatric Voice Handicap Index (pVHI) and the Children's Voice Handicap Index-10 (CVHI-10). Objective outcome measures included acoustic analysis of fundamental frequency, jitter, shimmer and noise-to-harmonic ratio. RESULTS AND CONCLUSIONS: Significant improvements in perceptual ratings of overall dysphonia severity levels and pVHI scores were found in the treatment group. No significant changes in acoustic measures and CVHI-10 scores were noted in any of the three groups. Interestingly, an improvement in perceptual overall dysphonia severity levels at post-evaluation was observed in the no treatment control group.

Singer's Nodules: Investigating the Etiopathogenetic Markers Progressing Their Pathogenesis and Clinical Manifestations.

Vocal nodules (or Singer's nodules) are benign vocal cord structures which are commonly encountered by clinicians. Though phonetic trauma/abuse is thought to be the main cause of the development of vocal nodules, the exact etiopathogenesis remains unknown. Hence, we compared the immunohistochemical markers for proliferation (Ki-67), apoptosis (TUNEL), growth (EGFR), ischemia (VEGF), inflammation (IL-1α and 10), and immunoreactive innervation (PGP 9.5), in vocal nodule tissue samples obtained from 10 females (17-56 years) and vocal cord tissue from seven controls. A statistically significant increase in Ki-67, TUNEL, EGFR, VEGF and IL-1α expression was noted (p < 0.05) between nodule tissue and control tissue in both epithelial and subepithelial layers. However, the difference was non-significant for both IL-10 and PGP 9.5 (p > 0.05). All markers demonstrated moderate to strong positive correlations, except for IL-10. These findings suggest increased cellular growth and proliferation in vocal nodules coupled with a persistent presence of inflammatory and ischemic environment. Furthermore, global prevalence of apoptotic cells and decreased anti-inflammatory cytokines highlight the presence of underlying complex mechanisms in the etiopathogenesis of vocal nodules, with age having a negligible impact on the marker levels. Our results could potentially further our knowledge in understanding the effects of different treatment modalities available at the cellular level.

Effects of vocal nodules on acoustic characteristics of voice in children†:†an acoustic analysis of voice.

Objective : In the present study, an attempt was made to evaluate the acoustic characteristics of voice in pediatric patients with vocal nodules using acoustic analysis of voice. Methods : Thirty-five pediatric patients with vocal nodules and 32 control children without dysphonia were enrolled in this study. Their voice samples were analyzed using the Multi-Dimensional Voice Program. Acoustic parameters of voice, such as pitch period perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and noise-to-harmonic ratio (NHR), were measured. Results : In phonation at a loudness of over 80 dBA, the PPQ, APQ, and NHR values of the voice significantly increased in children with vocal nodules than in the control children without dysphonia. The sensitivities and specificities of PPQ, APQ, and NHR for prediction of vocal nodules in children were 62.86% and 84.38%, 74.29% and 75.00%, and 31.43% and 93.75%, respectively. Discussion : The present findings suggest that vocal nodules affect vocal fold vibration, resulting in impaired control of pitch and loudness leading to increased noise components. NHR could be used to evaluate the efficacy of treatment, such as voice rehabilitation, in pediatric patients with vocal nodules because of its high specificity for prediction of vocal nodules in children.

Self-Assessment of Vocal Fatigue in Muscle Tension Dysphonia and Vocal Nodules: A Preliminary Analysis of the Discriminatory Potential of the Croatian Adaptation of the Vocal Fatigue Index (VFI-C).

In this paper the authors hypothesize that the intensity of subjective experience of vocal fatigue (VF) potentially reflects primary (hyper) functional vocal disorders (primary muscle tension dysphonia - MTD) differently than structural vocal disorders of functional etiology (MTD type 2a). Given the reported benefit of self-evaluation in the quantification of VF, the goal of this study was to test the potential of the Croatian adaptation of the Vocal Fatigue Index questionnaire (VFI-C) in order to show different VF intensities for the two above-mentioned diagnoses of vocal disorders. In total, 69 vocal nonprofessionals of both sexes (average age 41.5 years, ±13.8 years), with phoniatrically determined vocal disorders of varying etiology and 50 vocal nonprofessionals of both sexes without vocal disorders (average age 44 years, ±14.7 years), recruited at otorhinolaryngological clinics at medical centers in Zagreb and Split, completed the VFI-C. Psychometric characteristics of the VFI-C were determined by calculating Cronbach's alpha and the intraclass correlation coefficient , and by employing factor analysis, and the nonparametrical Mann-Whitney U test. Considering the favorable psychometric data, a descriptive analysis of the VF self-evaluation results was done for groups of participants with MTD diagnoses (10 people with an average age of 33.4, ±5.9 years) and vocal nodules ( 21 people with an average age of 37.3, ±12.8 years). A comparison was made of the average results of the MTD and vocal nodules groups using the nonparametric Mann-Whitney U test. Given that perceived VF was found to be greater in the MTD group, it appears that the self-evaluation of VF has a discriminatory potential for different vocal difficulties, which justifies the further verification of the complementary usefulness of VF gradation in clinical descriptions of different vocal disorders.

The Hellenic Voice Handicap Index of Different Laryngeal Mass Lesions: A Receiver-Operating Characteristic Analysis.

BACKGROUND: Voice disorders influence the quality of people's life. When the type of disorder is determined then the clinicians are capable of finding their patients' needs and address their complaints concerning their vocal problems. One of the most used tools, for assessing the patients' quality of life (in accordance with their vocal status), is the Voice Handicap Index. In this study, we determined the cut-off scores of Voice Handicap Index for population with laryngeal mass lesions such as vocal polyps and nodules. The calculated cut-off points further guide clinicians toward applying a needed interventional method/therapy even in the cases where the condition of a person could not be easily estimated. METHODS: The study involved 130 participants (aged 19-74). Specifically, 90 nondysphonic people served as the control group, while 40 participants had already been diagnosed with voice disorders due to laryngeal mass lesions. Participants who were diagnosed with a laryngeal inflammation or had undergone a surgery were excluded from the study. The cut-off scores were determined through a receiver-operating characteristic (ROC) analysis. RESULTS: The calculated cut-off points were 19.50 for the total score of VHI, 7.50 for the functional domain, and 8.50 for the physical and the emotional domain. CONCLUSIONS: The aforementioned cut-off points could be used in empowering the everyday clinical practice. Moreover, their knowledge could help the construction of an individualized therapy plan, as well as monitoring-biofeedback tool for the populations with vocal fold lesions.

Pediatric dysphonia: It's not about the nodules.

OBJECTIVE: Despite the fact that vocal nodules are the most common cause of chronic dysphonia in children, uncertainty and lack of consensus complicates practically every diagnostic and management decision. Selecting an optimal staging system is fundamental to understanding a disease process, mandatory for uniform reporting, and crucial to predicting natural history and treatment outcomes. The ideal prognostic model for vocal nodules is under intense debate. The purpose of this study was to analyze the predictive power of vocal nodule grade to severity of voice metrics in children. METHODS: Seventy-nine patients diagnosed with vocal cord nodules between 2006 and 2012 were drawn from UPMC Children's Hospital of Pittsburgh Voice, Resonance and Swallowing Center Research Registry. Subject age at time of diagnosis, nodule grade, relevant co-morbidities, scores on The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), parent-reported Pediatric Voice Handicap Index (pVHI), the phonotraumatic behaviors profile, habitual speaking pitch fundamental frequencies, pitch range, volume intensity, and s/z ratio were recorded and compiled into a de-identified database for analysis. RESULTS: Based on the Kruskal-Wallis H Test, there was no statistically significant correlation between nodule grade and total pitch range (p = .21), s/z ratio (p = .50), volume intensity (p = .33), overall CAPE-V Scores (p = .15), or pVHI Scores (p = .29). Chi-squared tests also revealed no significant associations between nodule grade and abnormality in habitual speaking pitch (p = .14 for fundamental frequency while sustaining a vowel sound, p = .37 for fundamental frequency while speaking structured tasks i.e. counting, or p = .76 while speaking in conversation). CONCLUSION: The current "gold-standard" for grading vocal nodule size suggests that the nodules themselves are not driving the standard dysphonic metrics that are most commonly collected and monitored in such children. This outcome is consistent with other studies reporting similar findings and was expected based on the inconsistencies in the reported literature to date. By extension, the conventional wisdom of avoiding surgical treatment of vocal nodules in children seems prudent as there is little evidence to suggest that the nodules themselves are "driving" the severity of the dysphonia. Ultimately identifying the true "drivers" of dysphonia in children will suggest alternative therapies that are more specific and directed to the pathophysiology. Most pediatric voice care professionals will welcome such discoveries as those in the front line of patient care are often rendered helpless and frustrated.

Laryngeal Web as a Possible Cause for Nonabsorption of Vocal Nodules in Boys After Puberty.

OBJECTIVES: Vocal nodules are frequent in children and tend to be reabsorbed after puberty, especially in boys. The aims of the present study were to analyze the progression of nodules in boys after puberty and to investigate the role of microweb in the persistence of these lesions. METHODS: Clinical and videolaryngoscopy evaluations were carried out in boys with vocal nodules treated between 2009 and 2016, followed up to the age of 17 years or until remission of symptoms and reabsorption of the nodules. Boys with vocal nodules who underwent regular vocal therapy are included in the study. The outcomes were remission of symptoms and of the nodular lesions. RESULTS: A total of 34 boys with vocal nodules were diagnosed, of which 21 completed follow-up. Mean age of the first evaluation was 9 years (5-11 years) and of end of treatment was 14 years (13-18 years). Mean number of videolaryngoscopy per child was five. After adolescence there was complete remission of symptoms and of the lesions in 15 children (71.4%), partial remission in four (19.0%), and no remission of symptoms and of the lesions in two cases. In these two, videolaryngoscopy identified the presence of microweb and nodules. CONCLUSIONS: Favorable reabsorption of the vocal nodules after adolescence was observed in the majority of the boys who underwent voice therapy; however, in two cases there was no remission of symptoms and of the lesions. The unfavorable course can be attributed to anterior laryngeal microwebs.
