One of the most relevant biomechanical parameters evaluated was the vocal fold stiffness, which may be estimated separately on the body (musculus vocalis
) and the cover (lamina propria).
TP3 is effective for diseases such as vocal fold atrophy, sulcus vocalis
, mutation voice disorder, and scarring.
It was found that vocal nodules were observed in 22, Vocal polyps in 12, Papilloma in 08 and Retention Cyst in 06, Tuberculous Laryngitis in 03, Sulcus Vocalis
in 04 patients (n = 60), (Table 9).

Most of these studies have focused on pacing of vocalis
muscles for bilateral VCP; for example, electrical stimulus to the paralyzed posterior cricoarytenoid (PCA) muscles in human larynx has induced vocal fold abduction and restored ventilation through the glottis in case of bilateral laryngeal paralysis .
Instead its promise was cut short as, just years later, Fisher discovered she was suffering from congenital disorder sulcus vocalis
- holes in her vocal cords.
Furthermore, the space between the bilateral vocalis
muscles is occupied by the rima glottidis (Fig.
It launched a successful career, but in 2011 she was diagnosed with congenital sulcus vocalis
- holes in the vocal cords - and has undergone three operations.
