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.
Laryngeal paralysis in animals is a condition in which the nerves and muscles that control the movements of one or both arytenoid cartilages of the larynx cease to function, and instead of opening during aspiration and closing during swallowing, the arytenoids remain stationary in a somewhat neutral position. Specifically, the muscle that ...
Investigations into idiopathic laryngeal paralysis by two groups (in Michigan and Tennessee) between 2005 and 2013 showed that dogs with ILP did not only suffer dysfunction of the laryngeal nerves; they found that this was just one prominent symptom of what was a very gradually progressing polyneuropathy of old age, which also affected other ...
The laryngeal cavity (cavity of the larynx) extends from the laryngeal inlet downwards to the lower border of the cricoid cartilage where it is continuous with that of the trachea. [ 12 ] [ 13 ] It is divided into two parts by the projection of the vocal folds , between which is a narrow triangular opening, the rima glottidis .
Spasmodic dysphonia, also known as laryngeal dystonia, is a disorder in which the muscles that generate a person's voice go into periods of spasm. [ 1 ] [ 2 ] This results in breaks or interruptions in the voice, often every few sentences, which can make a person difficult to understand. [ 1 ]
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10]
Currently, there are four types of implant procedures which are used to perform type 1 thyroplasty. Montgomery Thyroplasty Implant system. This system was discovered after years of research and the main advantage of this implant system is that it eliminates the process of customizing the implant at the time of surgery.
