Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation. [1] Due to the similarity in symptoms, VCD attacks are often mistaken for asthma attacks or laryngospasms.
This causes the person to use more force when speaking in an attempt to close the vocal folds completely, which in turn creates more trauma to the vocal folds. [9] Glottal insufficiency (when the vocal folds cannot close completely, often due to vocal fold paralysis) can also be an underlying cause of contact granulomas. [5]
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing.
The voice may be perceived as hoarse, [4] [5] due to aperiodic vibrations of the vocal folds, [5] and may also be perceived as breathy, [4] [5] due to an incomplete closure of the vocal folds upon phonation. [1] [4] The degree of hoarseness and breathiness perceived may vary in severity. This variability may be due to the size and firmness of ...
The human vocal cords are roughly 12 – 24 mm in length, and 3–5 mm thick. [9] Histologically, the human vocal cords are a laminated structure composed of five different layers. The vocalis muscle, main body of the vocal cords, is covered by the mucosa, which consists of the epithelium and the lamina propria. [10]
The researchers found that both people who had COVID-19 or another respiratory infection since May 2020 were more likely to have lingering symptoms than people who didn’t have either infection.
The adducted vocal folds do not close completely but instead remain partially open. The narrow opening between the folds is referred to as the glottis . [ 23 ] [ 7 ] As air moves through the glottis, it causes a distortion of the air particles which sets the vocal folds into vibratory motion.
