Temporomandibular Joint Subluxation

Subluxation Temporomand Jt


  • A recent study in the journal Anesthesia Progress presents a new technique for treating dislocation of the TMJ (temporomandibular joint) using a deep temporal nerve block.[dentistryiq.com]
  • This seemingly cumulative complexity of presentations observed with OFD may be explained by Lewit’s reference to compensations often developing ‘upstream’ of joint dysfunction and muscle imbalance (Lewit 1991).[chiro.org]
  • Case presentation We present the case of a 29-year-old Caucasian man with a non-traumatic bilateral anterior temporomandibular joint dislocation.[jmedicalcasereports.biomedcentral.com]
  • A manual reduction of the dislocation using IV sedation and a note entry on his medical record was all that was necessary to alert another doctor should this patient present with yet another temporomandibular joint dislocation.[nature.com]
  • Note that when the mandible is in its resting position and no dislocation is present, the coronoid process and anterior border of the ramus are not palpable as they are located posterior to the body of the zygoma (figure 2).[aliem.com]
  • It is a chronic disorder and the patient may complain of weakness in the joint while opening the mouth. Complete opening of the mouth is generally associated with pain.[phaa.com]
  • Pradhan, Jaisani, Sagtani, and Win (2015) identify six categories of predisposing factors to TMJ dislocations: congenital weakness in articular ligaments, iatrogenic factors, trauma, drug-induced, physiological, and systemic factors.[nursingcenter.com]
  • These include poor joint capsule integrity, weak articular eminence morphology, and muscle hypotonicity [ 5 ]. The diagnosis of TMJ dislocation is often clinically based in the first instance.[jmedicalcasereports.biomedcentral.com]
  • If BtA is injected into a muscle it is rendered weak and atrophic within a few days or weeks.[nature.com]
Severe Pain
  • Muscle relaxers may be prescribed for severe pain.[healthline.com]
  • Dislocation of the Mandible Clinical findings Dislocations of the mandible tend to be uncomfortable but not severely painful for the patient The presence of a fracture increases the pain Patients are unable to close mouth completely Difficulty speaking[learningradiology.com]
  • Chronic hypermobility associated with severe pain. Irreversible TMJ pain associated with clicking / grafting. Internal derangement.[maxfactutorial.wordpress.com]
  • It is also seen in severe epilepsy, dystrophia myotonia and Ehlers-Danlos syndrome. Prolonged dental appointments with long continuous opening of mouth can be one of the triggering factors for temporomandibular subluxation.[phaa.com]
  • Finally, systemic conditions such as epilepsy, arthritis, or other causes of involuntary muscle contraction also make patients prone to TMJ dislocations.[nursingcenter.com]
  • One conservative technique to consider is stimulation of the gag reflex. This technique involves the use of a dental mirror. The mirror is swept across the soft palate to induce a gag reflex.[nursingcenter.com]
  • Stimulation of the gag reflex by touching a mouth mirror to the soft palate may inhibit elevator muscle activity.[maxfactutorial.wordpress.com]
  • Another review from 1949 to 1976 reported that four out of 24 cases of long-standing dislocations were successfully reduced manually. 25 Manual reduction using the hippocratic method and a mouth gag, inserted between the molars under general anesthesia[cda-adc.ca]

Joint Subluxation
  • Psychiatric problems are also associated with tempormandibular joint subluxation. Treatment The treatment can be conservative or surgery may be needed. The conservative treatment consists of inducing a sclerosing agent inside the joint capsule.[phaa.com]
