2.20 Anterior-oblique view of the larynx demonstrating the course of the recurrent laryngeal nerve as it enters the larynx from the tracheo-esophageal groove. Although a detailed description of laryngeal anatomy is beyond the scope of this article, knowledge of the relevant anatomy is essential for the understanding of trauma mechanisms and their effects on laryngeal structures. Start Now. Healthy membranous vocal folds usually appear white in color and glistening with moisture. This gives a characteristic foliage arrangement to the plant. Inferiorly and laterally, the preepiglottic space is contiguous with the paraglottic space. Fig. 2 Laryngeal Anatomy Katherine A. Kendall The interpretation of laryngeal imaging in the evaluation of patients with voice problems requires a strong foundation in the anatomy and physiology of the larynx. Start studying VD: Chapter 2: Laryngeal Anatomy and Physiology. The conus elasticus is attached to the inner surface of the cricoid cartilage and fans superiorly and medially to provide shape and contour to the undersurface of the vocal folds (Figs. Clinically Oriented Anatomy, 5th ed. 1. Cancer. Unable to process the form. Gold G. Brandon Gunn Randal S. Weber The incidence of cancer of the larynx has stabilized at ˜10,000 cases reported in the United States per year. View Article. Illustration by Markus Voll.). Anatomy . It must be kept in mind that the under-surface of the vocal folds cannot be seen from a superior angle of view. Fig. (From THIEME Atlas of Anatomy, Neck and Internal Organs, © Thieme 2006. The recurrent laryngeal nerve (also a branch of the vagus nerve) provides motor branches to the rest of the intrinsic laryngeal muscles and sensory branches to the mucosa of the undersurface of the vocal fold and trachea. Poster: "ECR 2016 / C-0786 / Hypopharynx and larynx anatomy" by: " A. I. Fernández Martín 1 , N. Delgado Ronda 2 , E. Dominguez Franjo 3 , M. Martínez Martínez-Losa 4 , N. Alegre Borge 5 , J. Martínez Salazar 3 ; 1 Arganda del Rey, MADRID/ES, 2 Ávila/ES, 3Arganda del Rey/ES, … It runs deep to the epithelial covering of the vocal fold and superficial to the deep musculature of the larynx. This book comprehensively covers state-of-the-art cross-sectional imaging of the larynx. Anatomy and Physiology of the Larynx. Muscles, Innervation, and Blood Supply of the Larynx … (From THIEME Atlas of Anatomy, Neck and Internal Organs, © Thieme 2006. The ligament makes up the deep layer of the lamina propria and is involved in the attachment of the thyroarytenoid muscle to the connective tissue, that is, the lamina propria. • Fibroelastic cartilage • Leaf-shaped structure • Petiole – small narrow portion of the glottis. The ventricular or “false” vocal folds and the aryepiglottic folds are the result of a sheet of connective tissue known as the quadrangular membrane. Fig. Anatomy Video Lectures. (From THIEME Atlas of Anatomy, Neck and Internal Organs, © Thieme 2006. 2.7 and 2.8). The thyroid cartilage is shaped like a shield with a right and left lamina fusing in the midline (Fig. To the sides of the pharynx by the lateral glossoepiglottic folds. Illustration by Markus Voll.). For more presentations, please visit www.nayyarENT.com. … Clinicians familiar with normal laryngeal anatomy are able to detect alterations in the anatomy and functioning of the larynx due to pathology. They form barriers that divide larynx into compartments & serve to guide, limit the spread of laryngeal cancer It is contained partly within the rami of the mandible and extends caudally into the neck. The vocal process of left arytenoid (right of photo) by "V" and the petiole of the epiglottis by "P". ), Fig. Note the position of the muscular process of the arytenoid cartilage. The vertical orientation of the axis of the main magnetic field permits a solenoidal surface coil to be wrapped around segments of anatomy in the long axis of the body. 2.16, 2.17, and 2.19). Harnsberger HR. CT Scan of the Larynx: Overview, Laryngeal Embryology and Anatomy, Laryngeal Neoplasms 11/10/2016, 18:01 ... known as the petiole), and inferior to the hyoepiglottic ligament. It is therefore the laryngeal surface anatomy that is most pertinent to the clinical examination of the larynx and the use of laryngeal imaging. 2.8 Illustration of how the intrinsic laryngeal muscles act to move the laryngeal cartilages as viewed from above. The larynx consists of a cartilage "skeleton", as well as internal structures that are divided into three subsites, mainly for the purposes of laryngeal cancer staging:. The interarytenoid muscles run between the arytenoid cartilages and help to close the posterior glottis during voicing. ), Fig. The primary purpose of the larynx is to act as a sphincter. This allows an excellent depiction of the intricate anatomy of the larynx in order to study ventricular complex, submucosal laryngeal spaces, anteroposterior extension, laryngeal cartilage involvement and metastatic spread permitting to establish a TNM staging, and to recognize its impact above the array of therapeutic options. The larynx is also designed to maintain airway patency. The internal branch of the superior laryngeal nerve enters the larynx via an opening in the thyrohyoid membrane. The nerve then divides into an abductor branch that supplies the posterior thyroarytenoid muscle and an adductor branch that runs superiorly and anteriorly to supply the lateral cricoarytenoid muscle and terminates in the thyroarytenoid muscle.3. Discover (and save!) The arytenoid cartilages are pyramidal in shape with the vocal processes located anteriorly and the muscular processes located laterally. Abduction of the vocal folds results from contraction of the posterior cricoarytenoid muscles. Relevant anatomy and pitfalls related to ossification patterns of laryngeal cartilages . ... EPIGLOTTIS Omega shaped with a furled petiole 47. (From THIEME Atlas of Anatomy, Neck and Internal Organs, © Thieme 2006. Note the paraglottic fat ( arrow ). The vocal folds are _____ maximally. The larynx consists of a cartilage "skeleton", as well as internal structures that are divided into three subsites, mainly for the purposes of laryngeal cancer staging: Both the superior and inferior deep cervical nodes then drain into the right and left jugular trunks, which subsequently empty into the right lymphatic duct and the thoracic duct on the left. Laryngeal Embryology and Anatomy Laryngeal Embryology The larynx begins to develop around the fourth week of development. Mucosa . The radiological anatomy of the larynx is described in detail, and the imaging findings in benign and malignant laryngeal disease are extensively discussed. Note the conus elasticus and its role in shaping the vocal fold contour and the quadrangular membrane and its role in shaping the aryepiglottic fold and the ventricular fold.
