Why the Jaw Thrust?

The biggest impediment, after placement of an oral airway, is the relaxation of the soft tissue structures in the hypopharynx. These structures are inclined to collapse, thus obstructing airflow, while occurring from both front-to-back and side-to-side, thus greatly decreasing (or closing) the oropharyngeal airway opening.


In relation, literally every patient before and after anesthesia, CPR, or sedation, is provided with a manual jaw-thrust as they wake up to prevent the tongue and soft tissue structures from falling back and obstructing the airway. Furthermore, almost every patient intubated is provided with an airway to prevent biting of the soft endotracheal tube and the tongue. Both of these procedures involve protracting the lower jaw by pulling it forward relative to the upper jaw to open the airway.


Since current airways don’t sufficiently address these known physiological issues – we designed an oropharyngeal airway that focuses on these drawbacks. Since mandibular advancement has been clinically proven to open and maintain the oropharynx airway, we designed a mechanical jaw thrust right into the airway. The result was our Lower Jaw-Thrusting (LJT) Oral Airways!
