OBJECTIVE(S): The present study aims to evaluate the reliability and construct validity of the Czech version of the Voice Handicap Index (VHI-CZ) and determine the cut-off value to distinguish dysphonic patients from nondysphonic individuals. STUDY DESIGN: Prospective study, Parallel group design. METHODS: The study investigated 100 adult patients with dysphonia, divided into three groups based on the etiology of the voice problem (neurogenic, functional, and structural). Out of these, 25 patients were used for test-retest analysis, and 45 patients to determine the responsiveness to change. The control group consisted of 51 healthy subjects. All 151 individuals completed the VHI-CZ and were examined with the videolaryngostroboscopy. The internal consistency (Cronbach's alpha), the test-retest reliability (Intra-class Correlation Coefficient, ICC), and the construct validity were analyzed and the normative cut-off value was determined. RESULTS: The internal consistency of the VHI-CZ was excellent (Cronbach α = 0.984), and test-retest reliability was also excellent (ICC = 0.95, P < 0.001). The correlation between the self-assessed severity of the voice disorder and the VHI-CZ score was strong (Spearman's ρ = 0.877, P < 0.001). The VHI scores differences between dysphonic and nondysphonic patients were statistically significant (Mann-Whitney U test, P < 0.001). The differences among the three etiological subgroups (neurogenic, functional, and structural) were also statistically significant (Kruskal-Wallis test, P < 0.001). Moreover, the differences in the VHI-CZ total scores between pretreatment and posttreatment were statistically significant (Wilcoxon test, P < 0.001). The cut-off score of 13 points was found, by the analysis of the Receiver Operating Characteristic (ROC, Youden Index), to be most suitable for preselecting dysphonic individuals. CONCLUSION: The existing VHI-CZ showed excellent reliability and construct validity. The Czech VHI is a useful and valid monitoring tool for clinicians.

Introduction: Total thyroidectomy (TT) is one of the most common surgical endocrine surgeries. Voice impairment after TT can occur not only in patients with recurrent laryngeal nerve (RLN) transient paralysis, but also in cases of normal vocal cord mobility. Aim: To compare voice limits using a speech range profile (SRP) in patients before and 14 days after TT and to investigate the influence of the early results of voice quality after TT on the personal lives of patients. We focused on the perception of voice change before and shortly after TT. Materials and methods: A retrospective study, in the period 2018-2020, included 65 patients aged 22-75 years. We compared two groups of patients: group I (n = 45) (without RLN paresis) and group II (n = 20) (with early transient postoperative RLN paresis). Patients underwent video flexible laryngocopy, SRP, and Voice Handicap Index-30 (VHI-30). Results: In group I, the mean values of Fmax (maximum frequency) and Imax (maximum intensity) decreased in women (both p = 0.001), and VHI-30 increased (p = 0.001). In group II after TT in women, the mean Fmax and Imax values decreased (p = 0.005 and p = 0.034), and the frequency range of the voice was reduced from 5 to 2 semitones. The dynamic range of the voice was reduced by 3.4 dB in women and 5.1 dB in men.VHI-30 increased (p = 0.001). Conclusion: The study documented a worsening of the mean values of SRP, VHI-30, and voice parameters of patients in group II. Voice disorders also occurred in group I without RLN paresis. Non-paretic causes can also contribute to voice damage after TT. SRP and VHI-30 are suitable tools for comparing voice status in two groups of patients, including those with dysphonia. Our data support the claim that the diagnosis of a thyroid cancer does not necessarily imply a higher postoperative risk of impaired voice quality for the patient.

INTRODUCTION: To update the European guidelines for the assessment of voice quality (VQ) in clinical practice. METHODS: Nineteen laryngologists-phoniatricians of the European Laryngological Society (ELS) and the Union of the European Phoniatricians (UEP) participated to a modified Delphi process to propose statements about subjective and objective VQ assessments. Two anonymized voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 3/4. The statements with ≥ 3/4 score by 60-80% of experts were improved and resubmitted to voting until they were validated or rejected. RESULTS: Of the 90 initial statements, 51 were validated after two voting rounds. A multidimensional set of minimal VQ evaluations was proposed and included: baseline VQ anamnesis (e.g., allergy, medical and surgical history, medication, addiction, singing practice, job, and posture), videolaryngostroboscopy (mucosal wave symmetry, amplitude, morphology, and movements), patient-reported VQ assessment (30- or 10-voice handicap index), perception (Grade, Roughness, Breathiness, Asthenia, and Strain), aerodynamics (maximum phonation time), acoustics (Mean F0, Jitter, Shimmer, and noise-to-harmonic ratio), and clinical instruments associated with voice comorbidities (reflux symptom score, reflux sign assessment, eating-assessment tool-10, and dysphagia handicap index). For perception, aerodynamics and acoustics, experts provided guidelines for the methods of measurement. Some additional VQ evaluations are proposed for voice professionals or patients with some laryngeal diseases. CONCLUSION: The ELS-UEP consensus for VQ assessment provides clinical statements for the baseline and pre- to post-treatment evaluations of VQ and to improve collaborative research by adopting common and validated VQ evaluation approach.

The objective is to compare the long-term voice outcomes of vocal fold augmentation (VFA) using autologous fat injection via direct microlaryngoscopy versus office-based calcium hydroxylapatite (CaHA) injection. Patients with glottal insufficiency and a gap no greater than 3 mm caused by unilateral vocal fold paralysis or vocal fold atrophy were prospectively recruited to the study from September 2012 to September 2015. From September 2012 to May 2014, VFA was only performed using autologous fat via direct microlaryngoscopy under general anesthesia (N = 14). From May 2014 to September 2015, VFA was performed as an office-based procedure using a transoral approach to inject CaHA (N = 17). Videolaryngostroboscopic evaluation, subjective satisfaction with voice, voice handicap index (VHI), and maximal phonation time (MPT) were analyzed pre-injection and 12 months after VFA. A total of 31 patients were analyzed. One year after VFA, 67.8% of the patients were satisfied with their voice, with no significant difference between groups (P = 0.247). The mean improvement in VHI in the autologous fat group was 31.6 ± 16.82 versus 35 ± 27.24 in the CaHA group (P = 0.664). MPT improvement was also similar in the two groups: 5.5 ± 2.52 for the autologous fat group versus 6.0 ± 3.98 for the CaHA group (P = 0.823). Both autologous fat injection via direct microlaryngoscopy and office-based CaHA injection have good long-term results. There were no differences in the treatment results of the two procedures 1 year after injection.

BACKGROUND: The purpose of this study was to show our comparison of the quality of voice obtained after superficial transoral endoscopic cordectomies (types I, II, and III) according to the European Laryngological Society classification versus the more extended cordectomy (types IV and V) among patients with glottic precancerous lesions or early glottic cancer. METHODS: Sixty-two patients underwent vocal assessment after cordectomy (types I-V) for dysplasia, Tis, T1a, T1b, and T2 lesions. RESULTS: Cordectomy (types I-III) had good vocal outcomes. Cordectomy (types IV-V) showed less favorable outcomes, p < .005 in common parameters of voice range profile and symmetry in stroboscopy after cordectomy (types IV-V), with significant voice handicap index. Recurrences were found in 4 patients with T1b and T2 cancer. Two cases were managed by a higher type of cordectomy, and the other 2 by total laryngectomy. CONCLUSION: Effect of transoral laser microsurgery on quality of voice depends on the type of cordectomy and the site of the lesion.

PURPOSE: To evaluate 5-year voice outcomes of vocal fold augmentation (VFA) using autologous fat (AF) injection via direct microlaryngoscopy versus office-based calcium hydroxylapatite (CaHA) injection. METHODS: Retrospective study of patients who underwent VFA between 2012 and 2015, with a 5-year follow-up. Patients with a glottic gap of ≤ 3 mm caused by unilateral vocal fold paralysis or vocal fold atrophy were included in the study. VFA was performed using AF injection via direct microlaryngoscopy in 17 patients, and using office-based CaHA injection in 19 patients. Subjective satisfaction with voice, voice handicap index (VHI), and maximal phonation time (MPT) were analyzed pre-injection, and at 12 and 60 months post-VFA. RESULTS: Altogether 36 patients underwent VFA between 2012 and 2015, of whom 5 were excluded within 1 year post-VFA, and 2 were excluded between 1 and 5 years post-VFA. Of the remaining 29 patients, 3 (10.3%) underwent re-intervention at between 1 and 3 years post-VFA. Thus, the 5-year follow-up included 26 patients (72.2%; 11 males and 15 females). At 5 years after surgery, 73.1% of the patients were satisfied with their voice, with no significant between-group difference (P = 0.307). The mean improvement of VHI was 28.8 ± 17.82 in the autologous fat group versus 33 ± 26.24 in the CaHA group (P = 0.458). MPT improvement was also similar between the two groups: 6.2 ± 4.26 for the autologous fat group versus 6.3 ± 4.34 for the CaHA group (P = 0.667). CONCLUSIONS: Both AF injection via direct microlaryngoscopy and office-based CaHA injection yielded good and comparable 5-year results.

BACKGROUND: Glottal insufficiency, mostly caused by unilateral vocal fold paralysis (UVFP) or vocal fold atrophy can be treated by injection laryngoplasty (IL). Materials such as hyaluronic acid (HA) gels are now widely available and used to improve voice quality. Various durability and effects of HA injection laryngoplasties have been reported. The aim of this study is to provide a systematic review of the literature for the use of HA in injection laryngoplasties. METHODS: A systematic literature search was conducted in PubMed and Cochrane Libraries. Three reviewers assessed original research studies concerning vocal fold augmentation with HA for eligibility. English written full-text human studies from 2000 to 2020 with EBM level 1b-2 were included. In vitro studies, animal studies, case reports, case-control studies, correspondence and review articles, and articles with other injection materials were excluded. Demographical data, indication, type of HA, evaluation methods, follow-up, durability of implanted material and complications were assessed. RESULTS: A total number of 311 articles were found in PubMed and Cochrane Library, 13 studies were eligible for final analysis with 1063 patients, mean age of patients was 58.7 years. Main indication for HA IL was unilateral vocal fold paralysis, evaluation methods were subjective-VHI (Voice Handicap Index) questionnaire and objective-acoustic and aerodynamic measurements, mean time of follow-up was 5.9 months. Large-particle HA gels were more favorable for longer durability than small-particle HA, reported time of resorption of HA gels ranges between 6 and 12 months, and complication rate was low. CONCLUSION: Hyaluronic acid injection laryngoplasty increases voice quality, improves results of voice therapy, and can be recommended as overlap treatment before permanent medialization surgery. Compared to other injected materials, HA seems to have more favorable effect on vibratory functions of the vocal folds and thus on the voice quality parameters.
