“…Endoscopic and stroboscopic assessments of laryngeal structure and function offer valuable information regarding vocal fold mobility, phonatory glottal closure, the difference in level between vocal folds, and the presence of laryngeal compensation in patients with UVFP. These parameters are closely correlated with the perceptual and subjective voice outcome indicators [ 31 ]. Nevertheless, physicians and SLPs should be cautious about using visualization tools as the sole methods on which treatment is directly based.…”

The Korean Society of Laryngology, Phoniatrics and Logopedics appointed a task force to establish clinical practice guidelines for the management of unilateral vocal fold paralysis (UVFP). These guidelines cover a comprehensive range of management-related factors, including the diagnosis and treatment of UVFP, and provide in-depth information based on current, up-to-date knowledge. Detailed evidence profiles are provided for each recommendation. The CORE databases, including OVID Medline, Embase, the Cochrane Library, and KoreaMed, were searched to identify all relevant papers, using a predefined search strategy. When insufficient evidence existed, expert opinions and Delphi questionnaires were used to fill the evidence gap. The committee developed 16 evidence-based recommendations in six categories: initial evaluation (R1–4), spontaneous recovery (R5), medical treatment (R6), surgical treatment (R7–14), voice therapy (R15), and aspiration prevention (R16). The goal of these guidelines is to assist general otolaryngologists and speech-language pathologists who are primarily responsible for treating patients with UVFP. These guidelines are also intended to facilitate understanding of the condition among other health-care providers, including primary care physicians, nurses, and policy-makers.

“…We recorded F 0 only for all MDVP parameters because other parameters, including the noise-to-harmonic ratio, short-term frequency perturbation (ie, jitter; %) or short-term amplitude perturbation (ie, shimmer; %) had shown no significant difference in our previous studies. 21,22 The minimal F 0 (F 0 min), maximal F 0 (F 0 max) and corresponding range of the intensity were also obtained from VRP combining the methods described by Hallin et al and Uloza et al 23,24 Patients were asked to sustain the vowel /a:/. Subsequently, they were asked to produce the tone as softly and then as loudly as they could.…”

Background After surgery in the thyroid region, patients may present with phonation or singing difficulty, even within their vocal range. We designed a novel voice evaluation method that reflects subjective and objective voice complications of the surgery. Methods This tool recorded patients' voice ranges while singing, which was named the singing voice range profile (singing VRP). Patients were asked to sing “Happy Birthday,” which has a one‐octave scale, at a comfortable tone and intensity. The singing VRP, standard VRP and voice handicap index‐10 (VHI‐10) results were recorded before thyroidectomy and 1 and 3 months after thyroidectomy for 128 patients. For subgroup analysis, a group where the maximum F0 of standard VRP in 1 month postoperatively was lower than the highest singing F0 of the preoperative singing VRP was defined as “Collapsed group” and the other group was “Preserved group.” Results The changes in the highest, lowest and range of singing fundamental frequency (F0) had decreased at 1 month postoperatively. Subsequently, they had improved significantly at 3 months postoperatively but were lower than those preoperatively (all P < .05, except for the change in the lowest singing F0 between 1 and 3 months postoperatively, P = .274). In the subgroup analysis, the singing range of the collapsed group (n = 65) showed significantly lower VHI‐10 scores, range of vocal F0 and singing F0 than those of the preserved group (n = 63) at 1 and 3 months postoperatively (all P < .001). At 3 months postoperatively, the singing F0 range in the preserved group had recovered to the range before surgery (13.0 ± 1.3 vs. 13.1 ± 1.4, P = .746 for the preserved group, and 13.0 ± 1.3 vs 11.5 ± 2.4, P < .001 for the collapsed group). Conclusions Parameters measured by singing VRP showed a trend similar to the change in VHI‐10 and the maximum F0 of standard VRP. In addition, singing VRP allowed a qualitative classification of the postoperative voice function when combined with standard VRP. Therefore, it can be used as a supplementary voice evaluation tool to reflect the physiologic and functional aspects of voice.

“…To this date, various works have investigated relations between vocal fold movements and resulting acoustics. However, often only linear relations were explored [33][34][35][36] or data from a small number of subjects (N � 20) was used [33,[35][36][37]. Some relations between vocal fold oscillations and resulting acoustic signal are known with the most obvious one being the strong correlation between fundamental frequency of the vocal fold oscillations and the fundamental frequency of the resulting acoustic signal in sustained phonation.…”

Interdependencies between acoustic and high-speed videoendoscopy parameters

In voice research, uncovering relations between the oscillating vocal folds, being the sound source of phonation, and the resulting perceived acoustic signal are of great interest. This is especially the case in the context of voice disorders, such as functional dysphonia (FD). We investigated 250 high-speed videoendoscopy (HSV) recordings with simultaneously recorded acoustic signals (124 healthy females, 60 FD females, 44 healthy males, 22 FD males). 35 glottal area waveform (GAW) parameters and 14 acoustic parameters were calculated for each recording. Linear and non-linear relations between GAW and acoustic parameters were investigated using Pearson correlation coefficients (PCC) and distance correlation coefficients (DCC). Further, norm values for parameters obtained from 250 ms long sustained phonation data (vowel /i/) were provided. 26 PCCs in females (5.3%) and 8 in males (1.6%) were found to be statistically significant (|corr.| ≥ 0.3). Only minor differences were found between PCCs and DCCs, indicating presence of weak non-linear dependencies between parameters. Fundamental frequency was involved in the majority of all relevant PCCs between GAW and acoustic parameters (19 in females and 7 in males). The most distinct difference between correlations in females and males was found for the parameter Period Variability Index. The study shows only weak relations between investigated acoustic and GAW-parameters. This indicates that the reduction of the complex 3D glottal dynamics to the 1D-GAW may erase laryngeal dynamic characteristics that are reflected within the acoustic signal. Hence, other GAW parameters, 2D-, 3D-laryngeal dynamics and vocal tract parameters should be further investigated towards potential correlations to the acoustic signal.
