Superolateral dislocation of an intact mandibular condyle into the temporal fossa: case report and literature review

Abstract

Temporomandibular joint dislocation refers to the dislodgement of mandibular condyle from the glenoid fossa. Anterior and anteromedial dislocations of the mandibular condyle are frequently reported in the literature, but superolateral dislocation is a rare presentation. This report outlines a case of superolateral dislocation of an intact mandibular condyle that occurred in conjunction with an ipsilateral mandibular parasymphysis fracture. A review of the clinical features of superolateral dislocation of the mandibular condyle and the possible techniques of its reduction ranging from the most conservative means to extensive surgical interventions is presented.

Traumatic Anterosuperior Dislocation of the Intact Mandibular Condyle into the Temporal Fossa

“…Shen et al22 collected 23 cases of superolateral dislocation (SD) of the mandibular condyle from the literature (1969–2011). Recently, Sharma et al (2016) reported one case of SD 23. The present study reported only eight cases of anterosuperior dislocation of mandibular condyles into the temporal fossa.…”

Condylar Dislocation for Intracranial Fossa: a Review of the Last 10 Years

“…Early diagnosis is essential to avoid unnecessary intracranial management, but also to ensure that the neurosurgery team is available for a possible craniotomy if there is leakage or bleeding of brain fluid, hematoma, or dural rupture. 5,[7][8][9] The literature mentions that a closed reduction under anesthesia should be considered before an open reduction, especially among young patients. Closed reductions are thought to see more success within between 2 and 4 weeks after the injury, and can minimize growth disorders.…”

Post-traumatic superolateral temporo-mandibular dislocation with intact condyle: case series and literature review

“…Temporomandibular dislocation is a dislodgement of the head of the mandibular condyle from its normal position in the glenoid fossa [1]. Temporomandibular dislocations can be classified into different types depending on the direction taken by the condyles out of the glenoid cavity [2].…”
