LJT Oropharyngeal (Oral) Airways

LJT ORAL AIRWAYS INCREASE THE OROPHARYNGEAL OPENING AND CONTROL THE TONGUE

It is estimated that over 350 million oral (oropharyngeal) airways are used every year around the world, during anesthesia, on semi / unconscious patient’s and during CPR. But would it surprise you to know that current airways have been clinically proven to be deficient in maintaining the oropharynx airway. That’s why we developed LJT Oral Airways!

 

The two-leading oral (oropharyngeal) airways were introduced over 80 and 50 years ago respectively, but the simple fact is that medical science has taken leaps and bounds since that time but, unfortunately, with what we know today regarding anatomical physiology, they are an old “hold over” from the past and they do not adequately fulfill all of the requirements to maintain the airway in semiconscious / unconscious patients.

 

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 the size of the oral 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 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 asked ourselves, why not address these drawbacks and design a better airway? The result was our Lower Jaw-Thrusting (LJT) Oral Airways!

Issues with Current Oral Airways

After examination and on comparison, current Guedel and Berman airways are dimensionally very different in relation to the proportional measurements and it is easy to see that these inconsistencies do not correspond to any design and anatomical logic.

 

Further our studies showed that in Guedel and Berman oral airways possess no proportional dimensional standards being employed to the length change in the bite block and the radius of the C curve. When no proportional standards are employed than this impacts the radius of the back body portion and how it will control and impact the anatomical structures of the oropharynx, i.e., epiglottis, root of the tongue, etc. These dimensional inconsistencies greatly impact how either airway design functions in relation to the anatomical requirements to keep an airway open.

 

It should also be noted that without the jaw-thrust design element and the ability to control the tongue, the relaxed jaw will allow for the relaxed tongue to fall back into the oropharynx because there is nothing to support it, resulting in an airway obstruction, causing complications for the anesthetist and the patient.

 

Comparison of using current Berman oral airway (left) versus our LJT oral airway and the alignment angle of the maxillary and mandibular teeth and jaw under anesthesia. Notice that the LJT airway protracts the lower mandibular jaw and pulls the tongue and genioglossus muscle forwards and prevents the tongue from moving back on the epiglottis and ororpharynx, thus holding it away from the posterior pharyngeal wall.
