What Is a Dislocated Jaw?

Mandibular dislocation can have obvious openings, and only the rearmost teeth are in contact. The jaw midline is offset to one side, and the dislocation is one side. Inject local anesthetic (that is, 1% lidocaine 2-5ml) in the joint area Extra-pterygoid muscle attachment area allows the mandible to reset itself.

Mandibular dislocation

Mandibular dislocation can have obvious openings, and only the rearmost teeth are in contact. The jaw midline is offset to one side, and the dislocation is one side. Inject a local anesthetic (that is, 1% lidocaine 2 ~ 5ml) in the joint area Extra-pterygoid muscle attachment area allows the mandible to reset itself.

Reduction may be required by hand. Weakly stable drugs (such as diazepam 5-10 mg intravenously or midazolam 3-5 mg intravenously) and anesthetics (such as pethidine on average for healthy adults) 25 mg intravenously or 50 mg intramuscularly) is required but not absolutely necessary, especially when there is no time to prepare for intravenous injection. The longer the dislocation takes, the more difficult it is to reset and increase the likelihood of becoming a chronic problem. The lever should be used to fix the patient's head. The surgeon places the two thumbs at the outer oblique line of the mandible (outside of the third molar), and the other fingers are under the palatine tip. With the rotating force, the thumb is downward. And anterior pressurization, while the other fingers are pressurized upwards until the mandible is restored.

Barton bandage is used to fix the position of the mandible after reduction. Patients should avoid large mouth opening for at least 6 weeks. When the patient wants to yawn, he should use fists to hold the crotch to prevent large mouth opening. If this dislocation is not the first time If it occurs, you should ask an oral and maxillofacial surgeon for a consultation. Surgery is to tighten (shorten) the ligaments around the temporomandibular joint or trim the mandibular joint nodules (to make it easier to automatically reset in the future).

Self-reset:

First wrap your thumb with a small bandage, bend your arms upwards, palms facing you, cross your wrists, put your thumbs in your mouth, press the inner teeth of your lower jaw (place as far as possible), and hold the other fingers with the front of your chin. At this time, the thumb is facing down, the other fingers are facing up, and gently rest outward. note! !! !! There is no pain in this process. If the pain may be swelling or other symptoms, please go to the hospital immediately.

Dislocation prevention:

Do nt laugh, yawn, stutter, or eat more fruit. Closing your eyes when your mouth is wide open or holding your chin with your hand can also avoid dislocation of the mandible.
