Palpation

1. Coronoid Process: Begin with mouth closed, palpate inferior to the zygomatic bone. Ask the patient to open their mouth. If the coronoid process does not move forward to touch your finger then ask them to open further or adjust your finger location. Check all easily accessible coronoid aspects. Verbal cues are generally required for maintaining an open mouth. Palpation of the medial aspect can be accomplished intraorally if required.
2. Retrodiscal space
