What is the appropriate oropharyngeal size for a patient?
When determining the appropriate oropharyngeal size for a patient, one must assess where the oropharyngeal airway parts lie in relation to the patient’s anatomical landmarks. The flange should be approximated, externally, to where it is abutting the lips, and the tip should be able to reach the angle of the mandible.
