Are vocal cords ligaments?
Are vocal cords ligaments?
Both the folds consist of a muscle (the vocal muscle or internal thyroarytenoid muscle), a ligament (the vocal ligament) and a covering mucosa (see Fig. 2). The vocal ligament is the medial edge of the laryngeal triangular membrane (also called conus elasticus).
Is vocal ligament the same as vocal cord?
The Vocal Folds (plicœ vocales; inferior or true vocal cords) are concerned in the production of sound, and enclose two strong bands, named the vocal ligaments (ligamenta vocales; inferior thyroarytenoid).
What does pseudosulcus vocalis mean in medical terms?
Pseudosulcus vocalis refers to subglottic edema that gives the vocal fold the appearance of being three-dimensional, almost having the appearance of an open hotdog bun. The normal non-swollen, non-inflamed vocal fold appears to be a two-dimensional structure. Pseudosulcus is a finding usually associated with reflux and diffuse laryngeal edema.
Where is the sulcus on the vocal fold?
Sulcus vocalis is used specifically to describe a groove or depression of mucosa along the medial surface of the true vocal fold that is typically found on the leading edge of the vibratory surface 1). Sulcus vocalis is a structural deformity of the vocal ligament 2).
What are the causes and treatment of sulcus vocalis?
The cause of sulcus vocalis is not widely studied and is poorly understood. Sulcus vocalis may be congenital (present at birth) or secondary to vocal trauma, vocal abuse, infections, laryngoesophageal reflux, degeneration of benign lesions, or surgery 15).
Where is pseudosulcus located in the larynx?
Background: A pattern of edema on the ventral surface of the vocal fold, called pseudosulcus vocalis, was described in 1995. It refers to infraglottic edema extending from the anterior commissure to the posterior larynx.
