Trachea, Posterior View

Description

Arising inferior to the cricoid cartilage, the cervical trachea is oriented in the midline and is seen from its posterior aspect, where the C shaped tracheal cartilages open dorsally into a soft, membranous wall. Superiorly, the posterior lamina of the cricoid and the posterior laryngeal framework sit directly above the first tracheal ring, while the trachealis muscle spans the gap between cartilage ends to complete the airway circumference. Along the posterior wall, the trachea lies immediately anterior to the esophagus, a close relationship that is easiest to appreciate in a true posterior view. That membranous segment matters clinically because it is the compliant part of the airway, the region that can bow anteriorly during coughing or forced expiration and the site involved in tracheobronchomalacia and excessive dynamic airway collapse. It is also the vulnerable surface during esophagoscopy, transesophageal echocardiography, and prolonged intubation, where posterior wall pressure injury can contribute to tracheoesophageal fistula. For airway procedures, the posterior view clarifies why tracheostomy is kept in the anterior midline and why endotracheal tube cuffs are positioned with care. Use this illustration for head and neck anatomy teaching on the larynx and trachea, for anesthesia and critical care materials explaining intubation related injury patterns, and for otolaryngology or thoracic surgery references discussing posterior tracheal wall pathology and repair.
