- TMJ dislocations are generally a rare occurrence. Connective tissue disorders such as Ehlers-Danlos syndrome and Marfan syndrome increase the likelihood of dislocation.
- TMJ dislocations can occur after benign activities such as eating, yawning, vomiting, dental treatment, and laughing, but also occur after trauma.
- Three common techniques for reduction include: 1) Hooking both thumbs over the patient’s canines, placing a Bite Block in the mouth, and pulling down on the jaw 2) Performing the same technique as #1, but from behind the patient 3) Placing a 5-10g syringe in the back of the patient’s mouth near the molars and instructing the patient to attempt to roll the syringe around.
- Once the jaw is reduced, patient’s with brackets will have their jaw wired shut, which is the same principle as a shoulder dislocation getting a sling to promote healing.
- Be aware of where the wire cutters are in the emergency room in case of a patient with a wired jaw needs an emergent airway.
