The arytenoid cartilages are paired hyaline cartilages that articulate with the sloping upper border of the lamina of the cricoid cartilage by the cricoarytenoid joint. This joint allows movement of the arytenoid cartilages, which is vital in app...
The laryngeal cartilages are hyaline cartilages, with the exception of the epiglottis and vocal process of the arytenoid, which are fibroelastic cartilages.5,6 Hyaline cartilages undergo changes with time, with progressive enchondral ossification.7,8 Histopathologic studies demonstrated that the stage of the calcification and ossification is widely affected by age.9 The order of ossification is affected by the distribution of the mechanical forces applied to the laryngeal cartilages.8 Ossification begins first in the superior border of the lamina in the cricoid cartilage followed by the apex, body, and muscular process of the arytenoid cartilage, with the exception of the vocal process.10,11 Our aim was not to elucidate the pattern in which arytenoid ossification progresses, but we agree with the previously published observation that ossification initially occurs in the lateral one-third of the arytenoids peripherally and progresses to involve the center afterward.10,11 This is in concordance ...
Arytenoid adduction is a surgical procedure used to treat vocal cord paralysis. A suture is used to emulate the action of the lateral cricoarytenoid muscle and position the paralyzed vocal cord closer to the midline. This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients. Arytenoid adduction is often performed in conjunction with medialization thyroplasty. One of the key functions of the larynx is phonation, the production of sound. Phonation requires the vocal cords to be adducted (positioned towards the midline) so that they can meet and vibrate together as air is expelled between them. Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoid, thyroarytenoid, and interarytenoid muscles. These muscles act on the arytenoid cartilages at the posterior ends of the vocal cords and are innervated by the left and right recurrent laryngeal nerves. Damage to these nerves results in vocal cord ...
In Figure 2, the endoscopic images correspond to the 20 year-old horse with a cough and exercise intolerance. Notice the airway (green arrow) is significantly reduced compared to the "normal horse" in Figure 1. The clinically relevant anatomy includes the arytenoid cartilage (blue stars), vocal cords (red cross), and the laryngeal cicatrix (yellow arrows). In this horse, the arytenoid cartilage is thicker than normal and the vocal cords are adhered to each other. In addition, a thick scar or cicatrix has developed between the arytenoid cartilage and the epiglottis. Hence, the cause for the recurrent cough and exercise intolerance is due to a significant reduction in the airway at the level of the larynx. The airway reduction is caused by the narrowing of the laryngeal opening due to cicatrix formation between the arytenoid cartilage and between the vocal cords ...

The arytenoid /ærɪˈtiːnɔɪd/ is a single muscle, filling up the posterior concave surfaces of the arytenoid cartilages. It arises from the posterior surface and lateral border of one arytenoid cartilage, and is inserted into the corresponding parts of the opposite cartilage. It consists of oblique and transverse parts. ...
Objectives: The aim is; laryngeal conservative surgery indications and to help conservation surgery rates to increase, by comparing preoperative vocal fold and arytenoid movements with postoperative histopathologic examinations in carcinoma of the larynx and hypopharynx. Material and method: 30 patients with laryngeal carcinomas evaluated for preoperative vocal fold and arytenoid movements were included into our study. The movements of vocal folds and arytenoids were defined clinically as mobile, fixed or limited. Postoperatively, the laryngeal specimens were divided into subglottic, glottic and supraglottic areas and fixed with formaldehit and evaluated with a pathologist. The involvement of thyroarytenoid muscle, posterior cricoarytenoid muscle, cricoarytenoid joint, paraglottic area, conus elasticus, arytenoid cartilage were investigated. Results: In cases with limited movement of vocal fold and arytenoid movements preoperatively, the rate of thyroarytenoid muscle involvement was 33.3% (2/6), ...
The larynx consists of a cartilaginous framework comprising the single thyroid, cricoid, and epiglottic cartilages and the paired arytenoid, corniculate, and cuneiform cartilages. The larynx is suspended from the hyoid bone by the thyrohyoid membrane. The vocal folds run from the angle formed by the thyroid lamina anteriorly to the vocal process of the arytenoid cartilages posteriorly. Alteration in the position and length of the vocal folds is primarily the result of movement of the synovial cricoarytenoid joints, with a contribution from movement of the cricothyroid joints. Above the vocal folds run the false cords, formed by the medial border of the aryepiglottic folds. These are separated from the vocal folds by horizontal sinus known as the laryngeal ventricle, which contains numerous mucin-secreting glands. ...
This common problem is worst with small bougies, such as in this paediatric example of a child with severe burns and a difficult airway. The bevel of the ETT allows the tip of the tube to stick out right (laterally) of the bougie and snag on the right arytenoid cartilage. This can be remedied by withdrawing the ETT slightly (to disengage it from the arytenoid), effecting a one-quarter counter-clockwise rotation of the ETT on the bougie (bringing the bevel and tip of the ETT into a superior midline position snug with the bougie), and then advancing again.. ...

Resection of the arytenoid cartilage had been performed through an open-neck approach since early 1900s [8,14-18]. In 1948, Thornell [19] described the first endolaryngeal arytenoidectomy through the endoscopic approach. His technique later became the most widely accepted strategy for endoscopic arytenoidectomy. A temporary tracheostomy was used in the early perioperative period with his approach. The glottis is widened by partial mucosal resection over the arytenoid area extending into the aryepiglottic fold. This technique, along with its various modifications [14,20], demonstrated good results in terms of ventilatory improvement in patients with BVFP [21]. Arytenoidectomy was further advanced by application of lasers in surgery. The major advantage of using the CO2 laser include the precision of laser incision, the capacity to maintain hemostasis, and decreased postoperative edema [22,23]. In 1983, Ossoff et al. [24] first described the total arytenoidectomy procedure using the CO2 laser ...
The laryngeal functions are to regulate airflow, voice production and prevent inhalation of food. If the intrinsic muscles and/or the nerve supply of the larynx are not normal, laryngeal function is not normal. The cricoarytenoideus dorsalis muscle abducts the arytenoid cartilages at each inspiration. The laryngeal recurrent nerve innervates this muscle. Lesions to the laryngeal recurrent nerve, or to the cricoarytenoideus dorsalis muscle, result in laryngeal paralysis in dogs and cats. Laryngeal paralysis can be unilateral or bilateral. Medical treatment is necessary in an emergency situation; however, surgery is the definitive treatment. Laryngeal surgery is directed at removing or repositioning laryngeal cartilages that obstruct the rima glottidis. The four currently recognized surgical procedures used to correct laryngeal paralysis are: 1) unilateral or bilateral arytenoid cartilage lateralization; 2) ventricular cordectomy and partial arytenoidectomy via the oral or ventral laryngotomy ...
The lateral cricoarytenoid muscle is a muscle in the throat that adducts and medially rotates the arytenoid cartilage. This action adducts the vocal folds, increasing the pitch of the voice and closing the rima glottidis.

The wall of the larynx is supported by four cartilages namely a thyroid cartilage, a cricoid cartilage a pair of arytenoid cartilages. Thyroid cartilage is in the form of a broad ring, lying in the ventral and lateral walls of the pharynx. This cartilage is incomplete dorsally. The lower ring - like cartilage is cricoid which is broad dorsally and narrow ventrally. The arytenoids are present at the anterior end of dorsal side of cricoid. There is also a pair of small nodules called the cartilages of santorini present at the apex of arytenoid. Trachea The larynx opens into trachea or wind pipe that runs along the length of neck, ventral to the oesophagus. The trachea enters into the thoracic cavity and divided into two branches called Bronchi. The trachea and bronchi are supported by incomplete cartilaginous rings called tracheal rings. Each bronchus enters into the lung of its side. The bronchus is further divided into small branches called bronchioles within the lung. Each bronchiole divides ...
Laryngoplasty describes a surgery which changes the shape or configuration of the larynx and vocal folds. In most cases, the operation is used to reposition a paralyzed vocal fold to a position that is better for voice production, known as medialization laryngoplasty. This may involve placement of an implant and/or sutures to readjust the position of laryngeal cartilages. Laryngoplasty usually requires a skin incision in the neck. The size and location of this incision depends on the type and extent of laryngoplasty being performed.. A variety of implantable materials are available for laryngoplasty, including silicone, Gore-Tex™, and a substance called calcium hydroxylapatite. None has a clear advantage over another, but there are various considerations in implant selection. The advisability of repositioning certain cartilages (known as arytenoid adduction) and variations in technique are also debated among laryngologists. Both of these issues may be discussed with your surgeon.. Because the ...

True vocal cord paralysis signifies loss of active movement of the "true" vocal cord, or vocal fold, secondary to disruption of the motor innervation of the larynx. Disruption of innervation may occur along the length of the recurrent laryngeal nerves and the vagi and may include damage to the motor nuclei of the vagus. It should be differentiated from fixation of the vocal cord secondary to direct infiltration of the vocal fold, larynx, or laryngeal muscles. It should also be distinguished from fixation at the cricoarytenoid joint, encountered with rheumatoid arthritis or following traumatic intubation. ...
Laryngeal Paralysis is a condition in which the nerves and muscles that control the arytenoid cartilages (and so ultimately the vocal folds) become impaired in their function. During inspiration they open and during swallowing they close so impaired function leads to an increased risk of aspiration of food when eating and an inability to fully oxygenate when exercising.. It is usually an acquired disease but can be congenital, and is usually seen in large breed dogs such as Labs, Golden Retrievers, Newfies, and St Bernards. The cause is often unknown and more recently it is being associated with a more generalized degenerative neuromuscular disorder meaning that more than just the patients breathing is affected. Patients with Laryngeal Paralysis are often older, have voice changes (hoarse bark), decreased exercise tolerance, noisy breathing, particularly on inspiration, and a cough or gag after swallowing or drinking water. A definitive diagnosis requires direct visualization of the larynx ...
