Temporomandibular joint disc displacement is common in the world's population and could be associated with bone and functional characteristics of the temporomandibular joint. The aim of these study was to analyse the association between temporomandibular joint disc position evaluated by magnetic resonance imaging (MRI) and the inclination of the mandibular condyle evaluated by computed tomography (CT). One hundred and seventy temporomandibular joints (TMJ) were retrospectively analysed. Read More

Background: Dislocation of the mandibular condyle into the middle cranial fossa is a rare injury that can be seen after facial trauma. Early identification of condyle dislocation into the middle cranial fossa was difficult until the development of computed tomography, and diagnosis was often significantly delayed after the initial trauma.

Case Description: We present a rare case of a young woman who presents after a mechanical fall resulting in facial trauma with an avulsion condyle fracture with dislocation of the mandibular condyle into the middle cranial fossa. Read More

Although most of the cases of atlanto-axial dislocation (AAD) and basilar invasion can be managed by posterior approaches in the recent times, anterior decompression with stabilization is required in selected patients who persist with irreducible AAD even after manipulation of the C1-C2 facet joint under general anesthesia. A single stage endoscopic trans-oral decompression and stabilization can be used in such patients. It has not been described so far to the best of authors' knowledge. Read More

Dislocation of the mandibular condyle is one of several consequences of facial trauma that can be anticipated. The condylar neck is inherently weak and likely to fracture at the time of impact before dislocating into the middle cranial fossa. A review of the literature revealed that most cases of dislocation of the mandibular condyle into the middle cranial fossa are treated by open reduction and internal fixation via an extraoral approach or are treated conservatively with closed reduction.

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.

Intra-Articular Temporo-Mandibular Disorders (TMD) are characterized by displacement of the disc that causes the condyles to slip back over the disc thus resulting in TMJ discal damage and erosion of the condyle's bone. The etiology of temporomandibular disorder (TMD) is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. The study involved 46 joints in 27 patients with a diagnosis of Intra-Articular Temporo-Mandibular Disorders (TMD) according to Axis I of Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for Clinical and Research Applications and underwent surgery between 2011 and 2014.

Posterior dislocation of the mandibular condyle is a rare disorder caused by trauma to the chin accompanied by damage to the external auditory canal. Treatment of posterior condylar dislocation (PCD) is directed at repositioning the condyle into the glenoid fossa, preventing recurrent dislocations, and maintaining patency of the ear canal. With early intervention, closed reduction with manual manipulation is successful but could be ineffective for chronic protracted PCD. Read More
