“…Including the present case report, nine cases were deemed acceptable for evaluation and analysis, showing the ADIMC as a rare condition in the literature. The diagnosis, management, and correct classification of this type of dislocation has also been discussed in the literature, being that the open reductions29101112 were more applied than the closed reductions,81314 being directly related to the time of approach in relation to the trauma, as shown in Table 1 2891011121314…”

Temporomandibular joint (TMJ) dislocation, or luxation, occurs when the condyle crosses the articular eminence in such a way that it does not return to its correct anatomical position, unless aided by a reduction in external forces for TMJ. The diagnosis of condylar luxation is clinical; however, image exams are important in classifying the types of condylar luxation and associated fractures. Displacement of the TMJ can occur due to either an exaggerated mouth opening or a forced opening and occasionally is associated with a high-impact trauma to the jaw, the latter being an extremely rare condition. Few cases of anterosuperior dislocation of the intact mandibular condyles into the temporal fossa (ADIMC) have been documented in medical literature, many of which are associated with craniofacial trauma. This study describes the case of an ADIMC of the left side combined with facial fractures, as well as the treatment performed. A review of cases found in the literature from 1969 to 2017 was conducted through a detailed bibliographical study.

“…Dislocation of the temporomandibular joint (TMJ) is the dislodgement of the head of the condyle from its normal position in the glenoid fossa to anterior of articular eminence during the mandibular opening. It represents 3% of all reported dislocated joints in the body[ 1 ] and can be partial (subluxation) or complete (luxation), bilateral or unilateral, acute, chronic protracted, or chronic recurrent.

Objective: To evaluate the accuracy and effectiveness of ultrasound (US) guided autologous blood injection (ABI) for the treatment of chronic recurrent TMJ dislocation. Design: Prospective cohort study. Setting: Centre for medical education and research. Participants (or Animals, Specimens, Cadavers): Ninteen patients with chronic recurrent TMJ dislocation (Fifteen bilateral and fourteen unilateral). Interventions: Autologous blood injected, 2ml in superior joint space (SJS) and 1 ml in peri-capsular tissue (PT) under ultra sound guidance. Main Outcome Measure(s): Reduction in number of dislocation episodes, maximal mouth opening, pain (visual analogue scale) and TMJ sounds (present or absent) at the end of 2 weeks, 3 months, 6 months and 1 year. Results: At 2 weeks post operatively 18 patients (95%) were asymptomatic only one patient (5%) complained of Recurrence of dislocation and was treated successfully by a 2 nd injection. At subsequent follow up visits none reported dislocation. Conclusion(s): US guided ABI for patients with chronic recurrent TMJ dislocations serves as an alternative, minimally invasive, highly effective and accurate modality of treatment since it includes exposure without radiation, real-time visualization of soft tissues, visualization of the needle tip advancement, local anesthetic spread relevant to the surrounding structures which can be performed on an outpatient basis.

BACKGROUNDMandibular dislocation is not uncommon. It is the dislocation of the condyle from the glenoid fossa of the temporal bone, ultimately restricting movements. It is seen secondary to lax intra-articular ligaments or periarticular or as a result of injury. In the operative setting, applying a mouth gag for tonsillectomy or oral procedures is known to dislocate the temporomandibular joint, which can be relocated after removal of the mouth gag. Most of these are managed and reduced in emergency department. Manual reduction can be done for acute dislocations but the chronic cases are difficult to manage. 1 Unilateral dislocation is common but bilateral condition is rare. Herein we report a case of posterior dislocation of mandibular condyle, which was bilateral and longstanding before the patient presented to us.
