Spatiotemporal Analysis of High-Speed Videolaryngoscopic Imaging of Organic Pathologies in Males

Abstract

The results suggest that for males, the differences between healthy voices and organic voice disorders may be more pronounced within temporal characteristics that cannot be visually detected without high-speed imaging.

Quantification of Vocal Fold Vibration in Various Laryngeal Disorders Using High-Speed Digital Imaging

“…5,9,21,22 The reduction of amplitude and mucosal wave, as well as the phase delay, may originate from the mass effect of the polyp. Asymmetry of amplitude, mucosal wave, and phase may result from asymmetry in mass, tension, and mucoelasticity because most of the vocal fold polyps were unilateral in the present study.…”

“…Another advantage is that more advanced analysis is possible with HSDI. Data from videostroboscopy are usually evaluated subjectively [29][30][31][32][33][34] or by glottal area waveform analysis 35,36 or kymography, 37,38 whereas HSDI allows the use of a variety of methods such as LTG, 24 phonovibrography, 12,13,19,21,22 time series analysis, 15 and others. The third advantage of HSDI is that it allows more reliable quantitative analysis.…”

“…[4][5][6][7][8][9][10][11][12][13][14][15] Only in the past few years, several HSDI studies have been published that differentiate voice disorders and quantify their oscillatory characteristics. [16][17][18][19][20][21][22] However, the HSDI parameters reported in these reports have been focused on temporal aspects or left-right asymmetry, and size parameters that are routinely investigated by stroboscopic examination (such as amplitude and mucosal wave) have not been fully explored. Furthermore, HSDI research has been focused on vocal fold polyps and nodules, and there is a paucity of knowledge regarding other voice disorders.…”

Quantitative Analysis of Vocal Fold Vibration in Vocal Fold Paralysis With the Use of High-speed Digital Imaging

“…6,7 On the other hand, HSDI is usually evaluated not only by visualperceptual rating 4,8,9 but also by various other methods such as digital kymography, [10][11][12] laryngotopography (LTG), 13,14 phonovibrography, 15,16 and GAW. 8,17,18 Vocal fold paralysis (VFP) is a common disorder of the voice, and visualization of vocal fold vibration constitutes an essential role to its management. 19,20 First, the diagnosis is established by a combination of laryngeal examination via usual endoscopy, videostroboscopy or HSDI, laryngeal electromyography, computed tomography scan, and so forth.…”

Endoscopic Laser-Based 3D Imaging for Functional Voice Diagnostics

“…Typical vocal fold vibrations display a frequency in the range of 80-300 Hz for normal phonation. In order to capture such rapid movements adequately, high-speed videoendoscopy (HSV) with frame rates in the range of 4-20 kHz is used [3][4][5][6][7]. In the clinical routine, the most common methods for an evaluation of the vocal fold physiology and dynamical behavior are based on endoscopic, two-dimensional imaging (see Figure 1, left).…”
