Temporomandibular Joint Subluxation

Subluxation Temporomand Jt


Presentation

  • 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]
Weakness
  • 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]
Epilepsy
  • 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]
Gagging
  • 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]

Treatment

  • 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]
  • They took measurements before treatment began, then at increasing intervals from the end of treatment to 5 years after treatment.[tmj.org]
  • Non-invasive (conservative) treatment [ 16 ] Non-drug treatment Explanation and reassurance: Most TMDs are benign and will improve with non-invasive treatment. Rest, patient education and self-care: Limit excessive jaw movement by eating soft foods.[patient.info]

Prognosis

  • Treatment and prognosis Treatment should be reserved for symptomatic patients: medical: NSAIDs orthodontic: intraoral splints malocclusion correction (protrusive splints) decrease pressure on the joint (flat splints) surgical for correction of displacement[radiopaedia.org]
  • Prognosis The outlook is excellent for returning the dislocated ball of the joint to the socket. However, in some people, the joint may continue to become dislocated. If this happens, you may need surgery. 4/16/13 2002- 2017 Aetna, Inc.[colgate.com]

  • TMJ Treatment Prognosis Prognosis is favourable in the vast majority of patients treated conservatively and symptoms may improve without treatment. (Michelotti A, 2010).[physioworks.com.au]
  • Prognosis The prognosis for most isolated mandibular dislocations is good but varies based on the type of dislocation, as follows: Acute anterior mandibular dislocations carry an excellent prognosis with few cases that progress to recurrent dislocation[emedicine.medscape.com]

Etiology

  • Etiologic factors are uncertain but include occlusal dysharmony and psychophysiologic factors.[fpnotebook.com]
  • Dislocations may also result from dyskenesias that may be psychiatric in etiology, or due to abnormalities in the extrapyramidal system. 58 Anesthetic procedures are commonly associated with dislocations.[cda-adc.ca]
  • The etiology is uncertain, however, the condition is three to five times more common in females and symptoms typically become evident by the fourth decade. 10 Internal derangement is a progressive process.[radsource.us]
  • Etiology of subluxation / dislocation of TMJ: Causes: Intrinsic trauma. Over intention injury. Yawning, vomiting. Wide biting, seizure disorder. Extrinsic trauma: Trauma Flexion, extension injury to the mandible. Intubation with general anesthesic.[maxfactutorial.wordpress.com]

Epidemiology

  • This provides possible explanation for epidemiological studies showing a high prevalence of temporomandibular dysfunction (TMD) signs (90%) with approximately half of these presenting with symptoms (Solberg 1979).[chiro.org]
  • These disorders share the symptoms of pain, limited mouth opening and joint noises. [ 1 ] Epidemiology [ 1 ] TMJ symptoms are relatively common, affecting up to 25% of the population, although only about 5% seek medical help for their symptoms.[patient.info]
  • In more severe cases, surgery may be needed to reposition the jaw, particularly if repeated jaw dislocations have occurred. [12] Epidemiology [ edit ] Jaw dislocation is common for people who are in car, motorcycle or related accidents and also sports[en.wikipedia.org]
  • […] and damage to the eighth cranial nerve resulting in deafness. [12] Lateral dislocations are usually associated with mandible fractures. [13, 5] The condylar head migrates laterally and superiorly and can often be palpated in the temporal space. [14] Epidemiology[emedicine.medscape.com]

Pathophysiology

  • Aetiology [ 4, 5 ] TMDs are thought to have a multifactorial aetiology but the pathophysiology is not well understood. Causes can be classified into factors affecting the joint itself and factors affecting the muscles and joint function.[patient.info]
  • For the jaw to open it requires the lateral pterygoid muscle. [8] Pathophysiology [ edit ] There are four different positions of jaw dislocation: posterior, anterior, superior and lateral.[en.wikipedia.org]
  • Pathophysiology The mandible can dislocate in the anterior, posterior, lateral, or superior position.[emedicine.medscape.com]
  • Basic Science and Pathophysiology The mandible is a U shaped bone comprising two hemimandibles which are completely fused at the symphysis by the age of two years.[rcemlearning.co.uk]

Prevention

  • As Ben Franklin said, “an ounce of prevention is worth a pound of cure.”[raleighfacialpain.com]
  • Eliminating and preventing subluxations from the nervous system helps to improve and increase our health naturally, decreasing the use of medications.[chiropraticabenessere.it]
  • The blue arrow points to the articular eminence which prevents the mandibular condyle (black M) from relocating in the mandibular fossa (black arrow). For the same photo without the arrows, click here[learningradiology.com]
  • This helps tighten your jaw and prevents it from moving too much. You may need a fixation device after the use of a sclerosing agent. Fixation devices: You may have wires or elastic bands to prevent you from moving your jaw.[drugs.com]
  • Prevention TMJ dislocation can continue to happen in people with loose TMJ ligaments. To keep this from happening too often, dentists recommend that people limit the range of motion of their jaws.[colgate.com]
