The ring-like cricoid cartilage is the foundation of the larynx. Both the thyroid and arytenoid cartilages form mobile synovial attachments to the strong, stable cricoid cartilage above and the cricoid is firmly anchored to the trachea below. This hyaline cartilage structure is the sole laryngeal cartilage that forms a complete ring around the upper airway. It is narrow and thick in front and forms a tall thin plate of cartilage posteriorly where it reinforces the posterior wall of the larynx. They provide attachment for numerous muscles of the larynx. Like the other laryngeal cartilages, it grows much more rapidly in the male after puberty ...
When intubating a patient under general anesthesia prior to surgery, the anesthesiologist will press on the cricoid cartilage to compress the esophagus behind it so as to prevent gastric reflux from occurring: this is known as the Sellick manoeuvre. The Sellick Manoeuvre is typically only applied during a Rapid Sequence Induction (RSI), an induction technique reserved for those at high risk of aspiration. The Sellick maneuver was considered the standard of care during rapid sequence induction for many years.[2] The American Heart Association still advocates the use of cricoid pressure during resuscitation using a BVM, and during emergent oral endotracheal intubation.[3] However, recent research increasingly suggests that cricoid pressure may not be as advantageous as once thought. The initial article by Sellick was based on a small sample size at a time when high tidal volumes, head-down positioning, and barbiturate anesthesia were the rule.[4] Cricoid pressure may frequently be applied ...
Cricoid pressure is considered to be the gold standard means of preventing aspiration of gastric content during Rapid Sequence Intubation (RSI). Its effectiveness has only been demonstrated in cadaveric studies and case reports. No randomised controlled trials comparing the incidence of gastric aspiration following emergent RSI, with or without cricoid pressure, have been performed. If improperly applied, cricoid pressure increases risk to the patient. The clinical significance of aspiration in the emergency department is unknown. This randomised controlled trial aims to; 1. Compare the application of the ideal amount of force (30 - 40 newtons) to standard, unmeasured cricoid pressure and 2. Determine the incidence of clinically defined aspiration syndromes following RSI using a fibrinogen degradation assay previously described. 212 patients requiring emergency intubation will be randomly allocated to either control (unmeasured cricoid pressure) or intervention groups (30 - 40 newtons cricoid pressure

Accurate localisation of the cricoid cartilage is a key step in the successful application of cricoid pressure during rapid sequence induction. Poorly localised pressure is unlikely to confer any protective benefit to our patients and may have deleterious effects on laryngoscopy. We postulated that the use of ultrasound would greatly improve the accuracy of cricoid cartilage localisation prior to the application of cricoid pressure.
Calvin A. Brown, III, MD. In a randomized trial, cricoid pressure impeded tube passage through the glottis and prolonged intubation time.. Cricoid pressure has been associated with worsened glottic views and difficult tube placement during conventional laryngoscopy and intubation. It has not been previously studied in combination with the Pentax Airway Scope (AWS), a video laryngoscope with an integrated screen and tracheal tube channel.. In a single-center operating room trial, 60 patients aged 20 to 85 years were randomized to intubation with the Pentax AWS with either cricoid pressure or sham pressure. Sham pressure was accomplished by placing fingers on the cricoid ring but not applying downward force. Cricoid pressure was provided by an anesthesiologist who was trained to apply 30N of downward force using a cricoid simulator. Patients with anticipated difficult airways and those needing emergent intubation were excluded. Patients were induced with standard doses of propofol and ...
Cricoid pressure, also known by the eponymous name of the Sellick manoeuvre (in American English, Sellick maneuver), is a technique used in endotracheal intubation to reduce the risk of regurgitation. The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it. Cricoid pressure should not be confused with the BURP (Backwards Upwards Rightwards Pressure) manoeuvre, which is used to improve the view of the glottis during laryngoscopy and tracheal intubation, rather than to prevent regurgitation. As the name implies, the BURP manoeuvre requires a clinician to apply pressure on the thyroid cartilage posteriorly, then cephalad (upwards) and, finally, laterally towards the patients right. In 1961 Brian Arthur Sellick (1918-1996), an anaesthetist, published the paper Cricoid pressure to control regurgitation of stomach contents during induction of anesthesia-preliminary communication, describing the application ...

Results Over 20 years, 37 725 patients were attended by the service, and 72 patients received a scalpel cricothyroidotomy. An immediate primary cricothyroidotomy was performed in 17 patients (23.6%), and rescue cricothyroidotomies were performed in 55 patients (76.4%). Forty-one patients (56.9%) were already in traumatic cardiac arrest during cricothyroidotomy. Thirty-two patients (44.4%) died on scene, and 32 (44.4%) subsequently died in hospital. Five patients (6.9%) survived to hospital discharge, and three patients (4.2%) were lost to follow-up. The most common indication for primary cricothyroidotomy was mechanical entrapment of patients (n=5, 29.4%). Difficult laryngoscopy, predominantly due to airway soiling with blood (n=15, 27.3%) was the most common indication for rescue cricothyroidotomy. The procedure was successful in 97% of cases. During the study period, 6570 prehospital emergency anaesthetics were conducted, of which 30 underwent rescue cricothyroidotomy after failed tracheal ...

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 ...
MODEL RELEASED. Child with naso-gastric tube using sign language. Young girl aged 2 1/2 years with a permanent tracheostomy vent and a naso-gastric feeding tube, giving the sign for the letter a. The child has a congenital subglottic stenosis (SGS) grade 3, a narrowing of the subglottic airway where it passes through the ring-shaped cricoid cartilage. Grade 3 indicates the blockage is between 50% and 99%. A tracheostomy tube has been inserted below the cricoid to allow normal breathing. However this is below the larynx so the child is unable to talk normally and uses sign language to communicate. The child is unable to swallow so must be fed by tube. Treatment of SGS is normally by surgery, either by splitting the cricoid and grafting inserts of cartilage or by resection of the trachea. Congenital SGS is realtively rare, but is the third most common congenital airway problem. - Stock Image C003/8855
The median cricothyroid ligament is a flat band of white connective tissue that connects the front parts of the contiguous margins of the cricoid and thyroid cartilages. It is a thick and strong ligament, narrow above and broad below. Each lateral ligament is known as the conus elasticus. The lateral cricothyroid ligament is overlapped on either side by laryngeal muscles. The conus elasticus (which means elastic cone in Latin) is the lateral portion of the cricothyroid ligament. The lateral portions are thinner and lie close under the mucous membrane of the larynx; they extend from the upper border of the cricoid cartilage to the lower margin of the vocal ligaments, with which they are continuous. The vocal ligaments may therefore be regarded as the free borders of each conus elasticus, and extend from the vocal processes of the arytenoid cartilages to the angle of the thyroid cartilage about midway between its upper and lower borders. These anatomical structure have been called in many ...
The larynx, or voice box, has six different kinds of cartilages: the thyroid, arytenoid, cricoid, corniculate, cuneiform, and epiglottic. The cricothyroid ligament connects the thyroid cartilage with the arch of the cricoid cartilage.
The cricothyroid ligament is a median placed elastic ligament that is essentially the thickened median portion of the anterior cricothyroid membrane. It begins as a broad band attached to the upper anterior aspect of the cricoid cartilage and narrows as it ascends to attach to the lower anterior aspect of the thyroid cartilage ...

Laryngeal cancer is relatively uncommon, encompassing around 1% of all cancers. Of these, squamous cell carcinoma accounts for the majority, with a high male:female perponderance (5:1)1. Chondrosarcoma accounts for around one percent2. It usually presents with classic signs and symptoms of a laryngeal tumour; ie dysphonia, inspiratory stridor, dysphagia, odynophagia, neck mass, or persistent cough3. It is usually a slow growing tumour and therefore rarely presents with acute airway obstruction. It is most commonly centred on the cricoid cartilage (70 - 75%), however it can also arise from the thyroid cartilage, epiglottis and arytenoids in descending order of incidence4.. Symptoms depend on the location. Subglottic and endolaryngeal tumours will generally cause dyspnoea. Extralaryngeal tumours may compress the oesophagus resulting in dysphagia5. In our case the patient presented with inspiratory stridor and mild dysphonia, due to its location originating outside of the larynx, ultimately ...
The upper airway consists of the pharynx and the nasal cavities; however, some authors include the larynx and trachea as well. The pharynx is can be divided into the nasopharynx, oropharynx, and laryngopharynx.. The nose is composed of bone and cartilage, which are in turn attached to the facial skeleton. It is a pyramidal structure that is divided by a midline septum into two nasal cavities. The nasal cavities are lined with mucosa that can function to heat and humidify inspired gas. The paranasal sinuses drain into the nasal cavity. The posterior portion of the mouth opens into the oropharynx. When a patient is supine and unconscious, the tongue and lower jaw may slide posteriorly leading to airway obstruction within the oropharynx.. The pharynx is a U-shaped fibromuscular tube that extends from the base of the skull to the cricoid cartilage. It is bounded anteriorly and superiorly by the nasal cavity, followed more inferiorly by the mouth, and then the larynx. These borders divide the pharynx ...
However, Eckenhoffs article was in turn based on descriptions made half a century before by Bayeux, who reported the findings from anatomic dissections in 15 bodies of children between 4 months and 14 years of age, together with their corresponding plaster models. In that article, Eckenhoff describes the cricoid cartilage as a rigid structure that cannot be distended in order to pass the ETT, and describes how its parts come together to form a ring around the larynx. Eckenhoff actually clearly states the danger of extrapolating such cadaver findings to live human beings. Unfortunately a number of anesthesiology textbooks picked up on these anatomical descriptions of the pediatric airway since then ...
The normal canine thyroid gland consists of a right lobe, which extends from the caudal border of the cricoid cartilage of the larynx to the level of the 5th tracheal ring, and a slightly more caudal left lobe, which extends from the level of the 3rd to that of the 8th tracheal ring[2]. Infrequently, an isthmus located ventral to the trachea connects the lobes. The right lobe is in close proximity to the common carotid artery, the internal jugular vein, and the vagosympathetic trunk; the left lobe is in close proximity to the caudal laryngeal nerve and the esophagus. Ectopic thyroid tissue occurs frequently, located intrathoracically in the heart and heart base[3]. The parathyroid glands are closely associated with the thyroid gland, with a parathyroid gland frequently being located at the cranial surface of each thyroid lobe, and the second parathyroid gland frequently being embedded within the thyroid tissue. Lymph drains from the thyroid gland in both cranial and caudal directions[4]. Lymph ...
The thyroid gland is located between the C5 and T1 vertebrae. However, since the position of the thyroid gland can vary slightly among people, changes position during swallowing and can be enlarged (goiter), it is difficult to use the vertebral column as the sole landmark.. Thyroid pain is any superficial discomfort, tenderness or pain in the neck, below the thyroid cartilage (Adams apple) around the level of the cricoid cartilage that is usually exacerbated during swallowing or palpation. This tenderness or pain can extend all the way to the superior mediastinum. However the pain may not be so localized and could radiate to laterally (sternocleidomastoid muscles), superiorly (mouth, chin, jaw) or inferiorly (beyond the superior mediastinum to the chest).. ...
BACKGROUND: Resuscitation guidelines caution against extreme extension or flexion of an infants head because tracheal obstruction may occur. No data support this recommendation. The authors therefore examined the dimensions of the tracheal lumen in neutral, extended, and flexed head positions in infants undergoing general endotracheal anesthesia for elective surgery. METHODS: Eighteen healthy full-term infants were studied. A flexible fiberoptic bronchoscope was passed through a previously inserted endotracheal tube and positioned above the cricoid cartilage. Video recordings were taken in each of three head positions. Recordings were analyzed by an investigator blinded to head position. A computer-digitized technique was used to measure anterior-posterior and lateral dimensions and cross-sectional area. Data were analyzed using paired t tests and sign tests. RESULTS: No significant differences in mean tracheal dimensions with changes in head position were found. No infant had complete tracheal ...

The arytenoid cartilage is attached to the cricoid cartilage by small tough ligaments to form what is known as a saddle joint allowing rotation from side to side mainly about its long axis. Because the superior aspect of the posterior cricoid lamina slopes downwards the arytenoid cartilage rotates in a complex way such that the vocal process moves inwards and downwards during phonation and outwards and upwards during breathing. The arytenoids can also tilt forwards and backwards and slide along the length of the cricoarytenoid joint all of which allow fine tuning of the positioning and shaping of the vocal folds and epiglottic funnel both in speaking and singing.. ...

Anesthesiology published on 6 2016. Authors: Frédéric Heymans, M.D. et al. Background: When conventional approaches to obtain effective ventilation and return of effective spontaneous breathing fail, surgical airway is the last rescue option. Most physicians have a limited lifetime experience with cricothyrotomy, and it is unclear what method should be taught for this lifesaving procedure. The aim of this study is to compare the performance of medical personnel, naive to surgical airway techniques, in establishing an emergency surgical airway in cadavers using three commonly used cricothyrotomy techniques.. Methods: Twenty medical students, without previous knowledge of surgical airway techniques, were randomly selected from their class. After training, they performed cricothyrotomy by three techniques (surgical, Merkel, and QuickTrach II) in a random order on 60 cadavers with comparable biometrics. The time to complete the procedure, rate of success, and number of complications were recorded. ...
The thyroid (Greek thyreos, shield, plus eidos, form) consists of two lobes connected by an isthmus. It is located anterior to the trachea between the cricoid cartilage and the suprasternal notch. The normal thyroid is 12-20 g in size, highly vascular, and soft in consistency. Four parathyroid glands, which produce parathyroid hormone (Chap. 424), are located posterior to each pole of the thyroid. The recurrent laryngeal nerves traverse the lateral borders of the thyroid gland and must be identified during thyroid surgery to avoid injury and vocal cord paralysis. ...
Topographic Relationships Contours and Normal Constrictions of Esophagus, The esophagus begins in the neck as a continuation of the pharynx (cervical esophagus). This point of origin corresponds to the inferior border of the cricoid cartilage and the lower margin of the inferior pharyngeal constrictor muscle, also called the cricopharyngeus muscle, at about the level of the sixth cervical vertebra.

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. ...
Our human cadaveric airway course offers delegates a unique opportunity to repetitively perform and compare different techniques of airway management on a variety of cadaveric specimens. The focus of the course will be on visualising the larynx, and appreciating the differing appearance of human airway anatomy in the cadaveric specimens. There will be plenty of hands-on practice of the skills of conventional laryngoscopy, videolaryngoscopy using a variety of different devices, LMA and i-gel insertion, oral and nasal fibreoptic intubation and cricothyroidotomy. One of the pair of delegates will have the opportunity of performing the surgical cricothyroidotomy (Cutting the Neck Option).. Cadavers offer a unique opportunity for airway practitioners to interact with and visualise human airway structures without the ethical issues or risks associated with practising on live patients. Airway management and intubation on live patients cannot be done repetitively just to compare, test, or practice ...

The rationale for RSI is a perceived reduction in the risk of pulmonary aspiration in patients considered at risk, however the evidence behind this has recently (and appropriately) been questioned [Neilipovitz DT. Can J Anaesth 54: 748, 2007].. A traditional RSI includes fentanyl (1-2 ucg/kg, although remifentanil or alfentanil may be more reliable in terms of blunting response to DL [Jhaveri et. al. Anesthesiology 87: 253, 1997]) » Preoxygenation for 1-3 mins » defasiculating (panc 1-2 mg IV) » IV induction agent not followed by mask ventilation » SCh (1-2 mg/kg) » cricoid pressure » DL/ETT 45-90 seconds after SCh » OG/NG tube. The major concern regarding RSI is the potential for loss of airway (because paralysis is induced prior to establishment of ventilation, and given this risk it must be justified based on a dual assessment of the airway and aspiration risk (for a thorough discourse on the risk of pulmonary aspiration, see [Warner MA et al. Anesthesiology. 78: 56, 1993]). ...

The time intervals from start to location of the cricothyroid membrane were not significantly different between volunteers using the Seldinger versus the standard surgical technique. Times to tracheal puncture, as well as times to first ventilation, were significantly longer when participants were using the standard surgical cricothyroidotomy technique. Seven attempts at trachea placement had to be aborted in those using the Seldinger technique due to kinking of the guidewire, whereas six attempts had to be aborted in the group using standard surgical placement technique. Subsequent anatomic dissection revealed that the airway was accurately placed into the trachea through the cricothyroid membrane in 88.2% of the Seldinger technique attempts and in 84.0% of the standard surgical attempts. Six punctures of the thyroid vessels were observed in the cadavers receiving the standard surgical technique. Although the study in cadavers does not reflect real clinical situations, the shorter time to first ...

The knot in the throat is an involuntary contraction or spasm of the pharyngeal muscles (cricopharyngeal spasm) that causes the very annoying sensation of having something stuck in the throat, as if we were a foreign body which makes the Act of swallowing. This mysterious reaction of the body is produced most often by psychological issues, but what have immediate impact on the physical plane, i.e. a psychosomatic reaction in certain States of stress and anxiety. Until now I didnt have neither remedy nor palliative fast, by what my Quintana method will prove very satisfying in the sense that is of immediate application and easy to carry out, being effective in the majority of mild cases that have a single psychological origin. Follow it all the times occurring knot in the throat and see how it is always as effective. Spasm cricopharyngeal knot in throat causes this syndrome results from a spasm or involuntary spasm in the cricopharyngeal muscle. Symptoms are they may show the following: * ...
. Respiratory 1.The head is relatively large with a prominent occiput, the neck is short and the tongue is large. The airway is prone to obstruction because of these differences. 2.The epiglottis is large, floppy and U shaped. The trachea is short (approximately 4-9cm) 3.The glottic opening (laryngeal opening) is more anterior and the narrowest part of the airway is at the cricoid ring. (In the adult airway the narrowest point is the vocal cords). 4.An uncuffed endotracheal tube which has an air leak around it when positive pressure is applied to it should be used in children under 10 years of age. An uncuffed tube provides a larger internal diameter compared with a cuffed tube. 5. (Age / 2) Increased alveolar ventilation is achieved by an increase in respiratory rate

The objective of our work is to demonstrate in a large cohort of patients with cricotracheal stenosis that resection of long airway segments could be performed with no increased risk of postoperative complications. A consecutive series of patients getting cervical segmental cricotracheal resection (CTR) were reviewed. The typical segmental tracheal resection technique has been modified to accommodate long segment removal. Modifications include using trachea to enable the reconstruction of the larynx itself as well as the placement of a laryngosternopexy stitch between the thyroid lamina and the sternoclavicular ligament designed to take all of the tension off the anastomosis and to prevent inadvertent head extension ...
I struggle to ventilate the patient in the resus room, airway pressures are high, the bag doesnt empty properly. In my mind I plan ahead for the next step. Through my mind goes the thought - is this the one, the one that I cannot ventilate? Statistically it is not likely to be, but I am prepared to add two-person technique, airway adjuncts like nasopharyngeal or oropharyngeal, or supraglottic devices that I use frequently in theatre. I feel confident in the use of these methods, and (in the worst case) in cricothyroidotomy. I have practiced that numerous times on our live-tissue course on anaesthetised pigs. However - before I start any of these actions.. I routinely, almost as a reflex from theatre turn the patients head 45 degrees to the left, and then the bag suddenly empties easily - and I can ventilate the patient.. Some people think that time with TIVA in theatre has little value for emergency medicine and advanced prehospital care. I strongly disagree. This is some of the most relevant ...
