Trauma is often due to excessive use of the vocal folds such as by yelling, screaming, or singing. Though this often results in damage to the outer layers of the vocal folds, the subsequent healing process may lead to changes in the physiology of the folds. [1] Another potential cause of inflammation may be overuse of the vocal cords.
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.
The cough may persist for several weeks afterward with the total duration of symptoms usually around three weeks. [2] [1] Some have symptoms for up to six weeks. [3] In more than 90% of cases, the cause is a viral infection. [1] These viruses may be spread through the air when people cough or by direct contact. [2]
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.
Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. [4] [5] LPR causes respiratory symptoms such as cough and wheezing [6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. [7]
Voice disorders can be divided into two broad categories: organic and functional. [9] The distinction between these broad classes stems from their cause, whereby organic dysphonia results from some sort of physiological change in one of the subsystems of speech (for voice, usually respiration, laryngeal anatomy, and/or other parts of the vocal tract are affected).
Laryngospasm is an uncontrolled or involuntary muscular contraction of the vocal folds. [1] It may be triggered when the vocal cords or the area of the trachea below the vocal folds detects the entry of water, mucus, blood, or other substance.
Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea , which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough , inspiratory stridor and a hoarse voice .
