In English, this muscles name is the muscle of the shield-like cartilage and the U-shaped bone. The term thyro is from the Greek term thyreos for "shield." The Greek word thyreos comes from thyra meaning door and referred to a large, oblong stone that was used as a door. The term thyreos was later used to refer to large oblong shields used by Minoan warriors. The shields covered them from shoulders to feet, with the top of the shield having a notch for the chin. It was this shield that the ancient anatomist Galen envisioned when he named the laryngeal cartilage in the 2nd Century. The term hyoid comes from its resemblance to the Greek letter upsilon (u), which is aspirated as hy. This is combined with the suffix eidos meaning "shape or form ...

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 ...
The thyroid cartilage is a shield-shaped hyaline cartilage that is incomplete posteriorly. It has two large, flat plates, or laminae, that converge at the anterior midline where they form the so-called "Adams apple." Projecting from the posterior border of each lamina are superior and inferior projections, the superior and inferior horns of the thyroid cartilage. Attached to its inner surface at the midline is the elastic cartilage structure, the epiglottis. They provide attachment for numerous muscles of the larynx and ventral strap muscles of the neck. Like the other laryngeal cartilages, it grows much more rapidly in the male after puberty ...

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 ...

Knowledge of the pathology and spread of hypopharyngeal carcinoma has come from elegant studies of whole organ sections5,7-9 which have been confirmed by imaging studies.1 Because hypopharyngeal tumours tend to present at a relatively late stage, the early pattern of spread is more difficult to define than at some other head and neck sites.. Hypopharyngeal carcinomas are most often flat plaques with raised edges, and superficial ulceration. The carcinomas show a tendency for multisite involvement within the hypopharynx and extend into adjacent mucosal areas. The more extensive, multisite carcinomas tend to show superficial mucosal invasion and to be undifferentiated.3 The carcinomas tend to spread within the mucosa, beneath intact epithelium, for an average of 10 mm in the piriform sinus and 5 mm in the postcricoid region.5,8 Tumours spread through the muscle of the hypopharyngeal wall in most cases but the laryngeal cartilages resist invasion and are only invaded in a minority of ...
Klippel-Feil syndrome (KFS) is a genetically heterogeneous disorder characterized by variable degrees of bony fusion in the cervical vertebra. KFS patients may have spinal instability, disc degeneration, scoliosis, malformation of laryngeal cartilage with vocal impairment, cleft palate, facial dysmorphism, and limb and hand abnormalities. Sprengel anomaly and sensorineural, conductive or mixed hearing impairment are common. The clinical triad of short neck, low posterior hairline and limited neck movement is observed in less than 50% of KFS patients.. The Klippel-Feil syndrome NGS panel consists of five genes: GDF3, GDF6, MEOX1, MYO18B and RIPPLY2.. Copy number variation (CNV) analysis of the Klippel-Feil syndrome genes is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes. Panel genes are also offered as individual sequencing and deletion/duplication tests unless otherwise indicated.. ...

Adams apple is a feature of the human neck that is characterized by a protrusion formed by the angle of the thyroid cartilage surrounding the larynx. During puberty stage, thyroid cartilage elongates eventually much larger in males than in females. Because this protrusion on the neck is so a distinctive characteristic of an adult male, it may cause you great concern. Yet, Adams apple can be reducing in size by a Thyroid Cartilage Reduction procedure transforming from masculine to feminine remarkably. ...
The first step is to distinguish between oropharyngeal dysphagia and esophageal dysphagia from the patients symptoms. The evaluation begins with a careful history from the patient, which can provide direction towards the cause of dysphagia in the majority of patients. Tests performed on patients with dysphagia depend on whether the doctor thinks that the patient has oropharyngeal or esophageal dysphagia.. Investigation of oropharyngeal dysphagia starts with a careful neurologic examination to identify which nerves and muscles might be abnormal. Swallowing function testing of the mouth and throat can be performed with videofluoroscopy or modified barium swallow. This test involves giving the patient food items of different consistency (e.g. cookie, marshmallow) containing barium and observing the swallow on an x-ray screen (fluoroscopy). This test can show if the barium enters the larynx (opening to the breathing tube) while attempting to swallow, or if it passes normally through the upper ...

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.. ...

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.
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 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 ...
Evidence-based recommendations on endoscopic carbon dioxide laser cricopharyngeal myotomy for relieving oropharyngeal dysphagia (swallowing difficulties)
Cricopharyngeal myotomy is used to treat problems of swallowing. Cricopharyngeal myotomy can be performed either through the mouth, or via a small incision on the neck.
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 ...
The objective of this study was to immunohistochemically elucidate the major extracellular matrix constituents of rabbit tracheal cartilage. The impetus for this project is the need for crucial design and validation criteria for tissue engineering juxtaposed with the conspicuous lack of trachea extracellular matrix data in the literature. Tracheal tissue specimens were harvested from New Zealand White rabbits, and were immunostained for collagen I, collagen II, aggrecan and decorin; and a Verhoeff-Van Gieson stain was performed to visualize elastin. The most striking result was the highly organized relationship between distinct fibrous (containing collagen I, decorin and elastin) and hyaline-like (containing collagen II and aggrecan) regions of the tracheal wall. The tracheal cartilage stained strongly with collagen II throughout, with periodic bands of aggrecan in the tracheal arches, meaning that there were areas void of aggrecan immunostaining alternating with areas with strong aggrecan

AU - Ding, Dacheng. AU - Hillel, Alexander Tell. PY - 2017/11/1. Y1 - 2017/11/1. N2 - IMPORTANCE: Laryngotracheal stenosis (LTS) is a fibroproliferative disorder of the glottis, subglottis, and trachea. In models of fibrosis from other organ systems, the CD4+ T-cell response has been shown to regulate extracellular matrix deposition. Specifically, helper T cell 2 (TH2) promotes fibrosis, whereas TH1 and associated cytokines have been shown to be antifibrotic. However, this antifibrotic effect of the TH1 response has not been demonstrated in LTS. OBJECTIVE: To determine whether the TH1 cytokine interferon-γ inhibits the function of LTS-derived fibroblasts in vitro. DESIGN, SETTING, AND PARTICIPANTS: This in vitro controlled study included 6 patients with iatrogenic LTS undergoing routine surgical ...

Thyroid gland: It is located while watching trachea (windpipe) inside your neck of the guitar. The thyroid cartilage, that is the biggest cartilage from the larynx (voice box) is simply over the thyroid gland. It is split into two lobes (right as well as left) and it is linked to the centre with a slim link associated with thyroid cells, referred to as the actual isthmus. Due to the two linked lobes, the gland may be referred to as becoming formed just like a butterfly, or perhaps a bend connect. ...
As the passing thing falls down the oropharynx at a stretch, it is serious when entering the trachea, so the larynx must protect the larynx so that it does not get through. Normally, in such a case, we think that the entrance should close the lid all the time, or if you move the entrance, you may think about a mechanism that keeps the lid apart as if to escape from the approaching one. However, the place where the larynx is daring to pass through things is daring. The thyroid cartilage surrounding the entrance of the larynx and the hyoid bone are connected by a thyrohyoid muscle, and while the hyoid bone moves forward, the thyroid cartilage is pulled up at once to the trachea following it.. How does this relate to swallowing? Actually, the root of the epiglottic cartilage which protruded to the pharynx extends far to the front wall of the thyroid cartilage and the root is fixed like a hinge. In the latter half of pharyngeal phase, the epiglottis is pressed down from the top of the tongue base ...
