Abstract: A faceplate assembly that includes a faceplate frame (14) that mounts on a patient's face and a bite block (30) that holds an endotracheal tube (22) that extends into a patient's trachea to assist breathing. The tube is easily mounted on the bite block, and the tube can be shifted sidewardly to reduce discomfort to the lips of the patient. The bite block has a passage (42) through which the tube extends, the passage being spaced (D) sideward from the faceplate centerline (60). The faceplate can be removed from the patient, turned 180° about the centerline, and reinstalled using adhesive tape, to shift the bite block to the opposite side of the patient's mouth.
