Posterior Perspective of the Larynx

Description

Arising from a posterior view of the male larynx, the broad lamina of the cricoid cartilage dominates the field inferior to the thyroid cartilage, with its paired facets supporting the arytenoid cartilages at the posterosuperior margin. The posterior cricoarytenoid muscles sit symmetrically on either side of the cricoid lamina, running superolaterally toward the muscular processes of the arytenoids. Superiorly, the epiglottis appears as the uppermost landmark, while the airway continues inferiorly into the proximal trachea beneath the cricoid arch. Posterior laryngeal anatomy is where you orient for function. The posterior cricoarytenoid is the only intrinsic laryngeal abductor of the vocal folds, so this perspective is the cleanest way to teach or explain impaired abduction in recurrent laryngeal nerve palsy, when an arytenoid may sit paramedian and the rima glottidis fails to open. Cricoarytenoid joint mechanics also read well from behind, a practical correlation when discussing posterior glottic stenosis, arytenoid dislocation after intubation, or surgical planning for cordotomy and arytenoidectomy. Use this artwork for head and neck anatomy teaching blocks, otolaryngology and speech-language pathology coursework on phonation and airway protection, and surgical atlases that need clear labeling of the cricoid lamina, arytenoids, and posterior intrinsic muscles. It also fits patient-facing materials on vocal fold immobility where a posterior orientation clarifies why breathing, not just voice, is affected.
