Ovassapian and Williams airways. The Ovassapian Intubating Airway has two sections of curved walls between its side walls to guide the passage of the fiberoptic endoscope, while its distal lingual half has no posterior wall. The Williams Airway Intubator has a distal half that is open on its lingual surface, in contrast its proximal half consists of a cylindrical tunnel.

185:. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured. An alternative method for insertion, the method that is recommended for OPA use in children and infants, involves holding the tongue forward with a

The most commonly used oropharyngeal airway is the Guedel style. However, the landscape of oropharyngeal airways has expanded to include various designs tailored for specific medical procedures. Among these designs, those developed to facilitate flexible bronchoscopy are notable. Those include the

Oropharyngeal airways come in a variety of sizes, from infant to adult, and are used commonly in pre-hospital emergency care and for short term airway management post anaesthetic or when manual methods are inadequate to maintain an open airway. This piece of equipment is utilized by

Another notable alternative oropharyngeal airawy design is the Cuffed oropharyngeal airways (COPA). It intends to provide a better fit in the oropharynx by adding an inflatable cuff to a Guedel style airway.

In general, oropharyngeal airways need to be sized and inserted correctly to maximize effectiveness and minimize possible complications, such as oral trauma.
