1. A lower jaw and tongue thrusting endotracheal tube and flexible fiberoptic endoscope intubation (LJT-ET-FO) oral airway device, comprising
an elongate member having a distal end and a proximal end, the elongate member sized for insertion in the mouth of a patient and facilitation of air and medical instrument passage between the proximal and distal ends, including:
a flange assembly located at the proximal end of the elongate member including a lower lip flange, a pair of upper lip flanges, and a sliding insert that removably couples the pair of upper lip flanges, the sliding insert including a maxillary engagement surface that defines an upper cover of a passageway extending into the elongate member;
a tongue plate extending to the distal end of the elongate member;
a trough extending between the flange assembly and the tongue plate;
a mandibular flange projecting downwardly and transversely disposed at a first proximal end of the trough;
wherein the mandibular flange has a proximally facing surface that is located proximal to the maxillary engagement surface of the sliding insert but distal to the lower lip flange.
