Mandibular Dislocation

WHAT YOU SHOULD KNOW:

• A mandibular dislocation is a movement of your mandible (lower jaw) out of its place. You will not be able to put it back on your own. Normally, your jawbones (upper and lower jaw) meet in front of your ears, at the temporomandibular joint (TMJ). This joint is like the hinge of a door that lets you open or close your mouth. Your jawbones are held together and supported by ligaments and muscles. With mandibular dislocation, one or both sides of your lower jaw may be away from the TMJ. Your lower jaw may have moved forward, backward, up or down, or to the side. A mandibular dislocation may occur suddenly and may become chronic (long-lasting) and happen again and again.
  
  
• You may get a mandibular dislocation with a blow (hit) to your chin. Your jawbone may also become dislocated if you open your mouth too wide. It may also happen if you have a problem with the bones, muscles, or ligaments in your TMJ. Tests, such as x-rays or a CT scan may be done to check if your jaw is dislocated. Treatment is done to put your jawbones back in place and keep them stable to prevent another dislocation. This may include manual reduction, use of a sclerosing agent, devices, and surgery. You may also be given medicine for your pain and tight jaw muscles. With early treatment, your jawbone will be put back into its normal position and serious problems may be prevented.

AFTER YOU LEAVE:

Medicines:

• Keep a written list of the medicines you take, the amounts, and when and why you take them. Bring the list of your medicines or the pill bottles when you see your caregivers. Learn why you take each medicine. Ask your caregiver for information about your medicine. Do not use any medicines, over-the-counter drugs, vitamins, herbs, or food supplements without first talking to caregivers.
  
  
• Always take your medicine as directed by caregivers. Call your caregiver if you think your medicines are not helping or if you feel you are having side effects. Do not quit taking your medicines until you discuss it with your caregiver. If you are taking medicine that makes you drowsy, do not drive or use heavy equipment.

Ask your caregiver when to return for a follow-up visit. Keep all appointments. Write down any questions you may have. This way you will remember to ask these questions during your next visit.

Self-care:

• Activities: After having a reduction, exercise your jaw by opening and closing your mouth many times a day. If possible, avoid activities that cause you to open your mouth widely, such as yawning and laughing. Support your jaw whenever you do these activities. A bandage may be wrapped around your head and jaw if you had a chronic dislocation. This may help stop your jaw from opening too wide and having another dislocation. You may also use a head-chin strap. Follow your caregiver's instructions about activities that may be helpful.
  
  
• Diet: You may need to stay on a soft diet for some time after your jaw is put back in place. Soft foods include applesauce, baby food, bananas, cooked cereal, cottage cheese, eggs, gelatin, pudding, and yogurt.
  
  
• Ice: Apply an ice pack over your TMJ area for up to 48 hours. Do not apply ice directly to the skin. Packages of small vegetables in a thin towel can be used instead of an ice pack.

CONTACT A CAREGIVER IF:

• Your symptoms do not get better, or get worse.
  
  
• You have questions about your condition, treatment or care.

SEEK CARE IMMEDIATELY IF:

• Your jawbone moves out of place again.
