Background: Two external facial measurements have been recommended as reference criteria for estimating appropriate oropharyngeal airway sizes: the distances between the maxillary incisors to the angle of the mandible, and that from the corner of the mouth to the angle of the mandible.

Objective: To compare the two guidelines and to determine the optimal external facial measurements for the selection of an appropriately sized airway in adults.

Design: Randomised crossover study.

Setting: Operating theatres in a university hospital.

Patients: A total of 113 patients requiring tracheal intubation for general anaesthesia.

Interventions: Two oropharyngeal airway sizes were selected on the basis of two external facial measurements (tip of the upper central maxillary incisors to the angle of the mandible and corner of the mouth to the ang...
