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.
Blood-laced mucus from the sinus or nose area can sometimes be misidentified as symptomatic of hemoptysis (such secretions can be a sign of nasal or sinus cancer, but also a sinus infection). Extensive non-respiratory injury can also cause one to cough up blood. Cardiac causes like congestive heart failure and mitral stenosis should be ruled ...

[8] They can include: Dry or sore throat; Coughing (both a causal factor and a symptom of laryngitis) Frequent throat clearing; Increased saliva production; Dysphagia (difficulty swallowing)
The vagus nerves run down into the thorax, and the recurrent laryngeal nerves run up to the larynx. [ 3 ] : 930–931 The vagus nerves, from which the recurrent laryngeal nerves branch, exit the skull at the jugular foramen and travel within the carotid sheath alongside the carotid arteries through the neck.
However, more recent mechanical larynxes have demonstrated similar voice production to commercially available electrolarynxes. [4] Electrolarynxes were introduced in the 1940s, at a time when esophageal speech was being promoted as the best course in speech recovery; however, since that technique is difficult to master, the electrolarynx became ...
These conditions result from continuous damage to the laryngeal nerves [4] [3] and often lead to vocal disability. [6] Recurrent laryngeal nerve damage is the most common cause of vocal fold paresis. [4] The RLN is responsible for motor input to the vocal folds. [4] Physicians may also use the term recurrent laryngeal nerve paralysis. [19]
Transplants of the so-called voice box are extremely rare, and normally aren't an option for people with active cancer. Marty Kedian is only the third person in the U.S. ever to undergo a total larynx transplant – the others, years ago, because of injuries – and one of a handful reported worldwide.
In the United States, esophageal cancer is the seventh-leading cause of cancer-related deaths among males (making up 4% of the total). [78] The National Cancer Institute estimated that there were about 18,000 new cases and more than 15,000 deaths from esophageal cancer in 2013; the American Cancer Society estimated that during 2014, about ...
