Dislocation Of The Mandible

A spontaneous dislocation or dislocation of the lower jaw usually occurs in patients where this situation has already occurred several times in the history. Although a dislocation of the lower jaw is sometimes caused by a trauma of the incident typically begins with a wide mouth and then chewing pressure (eg. As in a large sandwich biting of hard bread), a wide yawning or a dental procedure. Patients who are prone to dislocation, may have naturally loose ligaments of the temporomandibular joint.

(See also overview of dental emergencies.) A spontaneous dislocation or dislocation of the lower jaw usually occurs in patients where this situation has already occurred several times in the history. Although a dislocation of the lower jaw is sometimes caused by a trauma of the incident typically begins with a wide mouth and then chewing pressure (eg. As in a large sandwich biting of hard bread), a wide yawning or a dental procedure. Patients who are prone to dislocation, may have naturally loose ligaments of the temporomandibular joint. Patients have a wide-open mouth, they can no longer close. Pain is secondary to the patient’s attempts to close the mouth. When the mandibular midline deviates to one side, the dislocation is one-sided. Although rarely employed, the injection of a local anesthetic can (z. B. 2% lidocaine, 2 to 5 ml) in the ipsilateral allow joint and the adjacent region with the approach of the lateral pterygoid a spontaneous return of the lower jaw. A manual reduction may be required (Unterkieferreposition.). Premedication can be used (eg. Diazepam 5 to 10 mg iv at 5 mg / min or midazolam 3 to 5 mg iv at 2 mg / min, and an opioid such as meperidine 25 mg iv or 0.5 to 1 ug fentanyl / kg iv), but is usually unnecessary, especially if lost by preparing the injection time. The longer the lower jaw is displaced, the more difficult the recovery and the higher the probability that later a dislocation occurs. Unterkieferreposition. The patient’s head is stabilized. The thumb of the examinee are on the external oblique line of the lower jaw placed (lateral to 3 molar range) or, after wrapping with gauze, the thumb, on the chewing surface of the lower molars. The other fingers are located under the lower jaw. The patient is asked to open his mouth wide, as if he would yawn, and the examiner directs the downward force on the molars while the upward force on the chin goes to the lower jaw gives way. A Barton-chin Association (Barton-chin bandage.) May be required for two to three days. Is that the patient avoids a wide mouth opening for at least six weeks at the most. When a yawn announced, the patient should put a fist under the chin to prevent a too-wide mouth opening. The food must be cut into small pieces. If the patient suffers from chronic dislocations and the more conservative treatment methods are exhausted, possibly a maxillofacial surgeon must be consulted. As a final treatment option the bands can streamlined operatively to the TMJ around (condensed) are, as an attempt to stabilize the joint, or it may be articulare tubercle be reduced (Eminektomie). Barton-chin bandage. This association ( “figure-of-eight bandage”) is wrapped around the head and the jaw to support the area below and in front of the jaw.
