Intralaryngeal Pressure Study

A medical procedure called endotracheal intubation involves inserting an endotracheal tube through a patient's mouth or nose and into the trachea to establish an airway, but the procedure can cause high pressure on the posterior larynx due to variations in the patient's hypopharyngeal-laryngeal angle, potentially leading to complications such as posterior subglottic stenosis if the patient has a highly acute angle or is intubated for an extended period of time. Posterior subglottic stenosis is characterized by the narrowing of the region below the vocal cords and above the trachea, resulting in breathing difficulties, stridor, and/or respiratory distress. To establish a mathematical relationship between the hypopharyngeal-laryngeal angle and endotracheal tube pressure, an airway simulation rig was constructed with a 3D adult larynx to measure pressure while varying the angle, using a 3D printed mold with high anatomical accuracy.
