Vocal Fold Atrophy in a Japanese Tertiary Medical Institute: Status Quo of the Most Aged Country

Quantitative Analysis of Digital Videokymography: A Preliminary Study on Age- and Gender-Related Difference of Vocal Fold Vibration in Normal Speakers

“…[42][43][44][45][46] In the present study, the CMC score, an indicator of physiological aging, was measured because the aging of voice is reported to be more influenced by physiological age than chronological aging per se. 47,48 The CMC score of recruited subjects in the present study (0.2 ± 0.9) was significantly smaller than that of patients with presbylarynx, the voice disorder resulting from pathological vocal aging, in the literature (1.3 ± 2.4), 49 which serves as a rationale for regarding the subjects recruited in the present study as physiologically normal.…”

“…Knowledge of the age-related variations demonstrated in the present study is especially important considering the worldwide trend for aging of society. 49,50 In addition, quantitative evaluation of some DKG parameters that have mainly been assessed in a qualitative manner so far (eg, amplitude, mucosal wave, and lateral peak) was introduced in this study. Some novel parameters were developed, as well (eg, mucosal wave persistence, lateral peak index, and IGW).…”

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

“…Lower SI values may originate from reduced vocal fold mass or mucoelasticity, probably due to flaccidity or secondary muscular atrophy of the fold. 44 Unlike the results for Oq, strong correlations with acoustic/ aerodynamic parameters were not observed (Table 6). …”

Treatment effectiveness for aging changes in the larynx

“…Presbylarynges is a diagnosis of exclusion for individuals over 60 years old who report hoarseness with no physiological explanation. [1][2][3][4] Characteristics are symmetrical bowing of the vocal folds at rest, 1,3,5 incomplete closure during vibration, 6,7 and compensatory false vocal fold (FVF) compression. 1,6,8 In addition, these characteristics could explain complaints of difficulty swallowing that also have been associated with dysphonia in the elderly (assumed to be presbylarynges).…”

[9][10][11] The primary treatment goal is to enhance glottal closure either by voice therapy or surgical interventions such as injection augmentation (IA) and bilateral thyroplasty surgery (BTS).…”
