Early in the morning, the hot search on Weibo was screened by [Roy Wang’s mandibular dislocation].
Is what [mandibular dislocation]? Commonly known as dislocation of chin, also known as [chin dropped], medically known as [dislocation of temporomandibular joint].
Dislocation is divided into anterior dislocation, upper dislocation and posterior dislocation. Anterior dislocation is more common and usually occurs after excessive mouth opening (e.g. Eating, yawning, laughing, singing, kissing, vomiting or oral treatment). Dislocation is less often caused by trauma. Drug-induced dystonia, epileptic seizures or tetanus infection can also lead to dislocation.
Patients often feel pain and anxiety after dislocation and need to seek medical treatment as soon as possible.
Why did your chin fall off?
Most of the time, the mandibular condyle and the skull fossa can cooperate well and work normally. But in some cases, Due to the impact of external force or excessive movement of temporomandibular joint, The range exceeds the normal limit, the condyle protrudes from the joint fossa and cannot return to the normal position in the joint fossa by itself, which is the so-called [dislocation]. At this time, the patient’s mouth is half open and cannot be closed. When grinding teeth, there are seams between the anterior teeth, the posterior teeth cannot contact, saliva flows out, and the speech is vague. If both joints are dislocated at the same time, the cheek becomes flat and the face becomes longer. If it is unilateral joint dislocation, the patient’s face is asymmetrical, and the midline of cheek and lower row teeth is biased to the side that is not dislocated.
[Chin Drops] Hurry to the Hospital to Reset
[Chin Loses] After that, you should go to the hospital in time for reset. Don’t be nervous during reset. Try to relax facial muscles. Doctors will choose different reset methods according to the situation.
After reduction of acute dislocation of temporomandibular joint, It is generally necessary to fix the mandible for a period of time. The patient needs to control the range of chin movement. If there is no restriction on the opening degree or the restriction time is not long enough after reduction, The surrounding tissues are not repaired in time, the ligaments around the joint are relaxed, and the condylar movement is restricted by little, which easily leads to recurrent dislocation or habitual dislocation. Over time, the chin may [fall] when singing loudly, the chin may [fall] when laughing loudly, and the chin may [fall] when eating with a wide mouth, which is really painful.
Temporomandibular joint is more difficult, pay attention to protection
Temporomandibular joint dislocation is only one of many temporomandibular joint diseases, Others include temporomandibular joint disorders, temporomandibular joint injuries, congenital or acquired deformities, inflammatory diseases and tumors. Among them, the more common joint problems include bouncing or murmur during joint movement, joint area pain, affected masticatory ability, limited mouth opening, etc. Serious cases even show different degrees of facial deformities. The prevalence rate of joint diseases is quite high and easy to repeat, which will seriously affect the normal life of patients.
The treatment of temporomandibular joint diseases has been a difficult problem for many years. However, with the deepening of medical understanding of joints and the progress of treatment methods, A large proportion of joint symptoms can be relieved or eliminated under the intervention of a doctor. If a joint problem occurs and requires early medical treatment, the doctor decides whether and how to intervene. Never delay the joint disease to become serious and complicate the treatment.
As for ordinary people, some what methods can protect temporomandibular joint?
First of all, we should solve all kinds of problems in the oral cavity in time. Let the teeth bite in a normal and healthy state, Such as treating affected teeth, repairing missing teeth in the mouth, correcting irregular teeth, You can’t eat with one tooth, That is, the case of unilateral chewing. Secondly, Care should be taken to avoid too much pressure on that joint, Such as opening your mouth for a long time or to a great extent, chewing hard objects continuously, etc. In addition, The condyle is very fragile, and external force impacting the joint area and other parts of the mandible may cause the condyle to break, which should be avoided as much as possible. Also, patients with definite joint problems should pay more attention to protection. For example, if people who have experienced repeated [chin drop], if they can’t help laughing, they can lightly hold their hands against their chin to prevent dislocation.
[Chin drop] and other kinds of joint diseases are not uncommon. To go deeper, The possible causes of temporomandibular joint diseases include trauma, extreme or long-term mouth opening, ligament and joint capsule lesions, neuromuscular disorders, psychological problems and many other factors. We don’t need to know all of them, but knowing the relevant information can at least help us not to be surprised when someone else’s chin dislocates.
