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.
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.
[20] [4] Nerve damage can be assessed by laryngoscopy, during which a stroboscopic light confirms the absence of movement in the affected side of the vocal cords. The right recurrent laryngeal nerve is more susceptible to damage during thyroid surgery because it is close to the bifurcation of the right inferior thyroid artery, variably passing ...
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]
“Treatment for vocal fold atrophy has focused on voice therapy, surgical therapies aimed at vocal fold medialization (when a damaged vocal cord is pushed toward a functioning one) or a ...
For some, spasms push the vocal cords too far apart, causing breathy and nearly inaudible speech. For others, such as Kennedy, the larynx muscles push the vocal cords closer together, creating a ...
She said the disease caused damage to her vocal cords in the three weeks between when she was bitten by a tick and when she started treatment for the infection. "There were seven years where I ...
Damage to these nerves results in vocal cord paralysis - the reduced mobility and inability to adduct one or both vocal cords. Many cases of vocal cord paralysis result from trauma during surgery. [2] Symptoms include hoarseness of voice, difficulty projecting, difficulty swallowing, and throat pain. [citation needed]
