INTRODUCTION: Free grafting or extracorporeal fixation of traumatically displaced mandibular condyles is sometimes required in patients with severe anteromedial displacement of condylar head. Majority of the published studies report the use of a submandibular, retromandibular or preauricular incisions for the access which have demerits of limited visibility, access and potential to cause damage to facial nerve and other parotid gland related complications. PURPOSE: This retrospective clinical case record study was done to evaluate the preauricular transmasseteric anteroparotid (P-TMAP) approach for open reduction and extracorporeal fixation of displaced and dislocated high condylar fractures of the mandible...

Several cases have been reported regarding superolateral, posterior, or superior dislocation of mandibular condyle. The anteromedial dislocation of fractured condyle is the most common among all. This article reports an unusual and unique case of dislocated fractured mandibular condyle wherein the fractured left condylar head was dislocated to the left anatomic angle of mandible. We have not found a single such case in the world English literature published till date. The presented case falls in the rarest of the rare category that will add to our previous knowledge about the types and extent of fracture dislocation of mandibular condyle...

Introduction. The mandibular condyle is the most common site of mandibular fracture. Surgical treatment of condylar fractures by open reduction and internal fixation (ORIF) demands direct visualization of the fracture. This project aimed to investigate the anatomic relationship of the tragus to the facial nerve and condylar process. Materials and Methods. Twelve fresh hemicadavers heads were used. An extended retromandibular/preauricular approach was utilized, with the incision being based parallel to the posterior edge of the ramus...

The principles of management of mandibular fractures differ in children when compared to adults and depend on the specific age-related status of the growing mandible and the developing dentition. This paper presents a case report with a complex facial trauma affecting the mandibular body and condyle region and dentoalveolar complex. Clinical examination revealed soft tissue injuries, limited mouth opening, lateral deviation of the mandible, an avulsed incisor, a subluxated incisor, and a fractured crown. CBCT examination revealed a nondisplaced fracture and an oblique greenstick fracture of the mandibular body and unilateral fracture of the condyle...

Various patterns of internal fixation of mandibular condyle fractures have been proposed in the literature. This study investigates the stability of two patient-specific implants (PSIs) for the open reduction and internal fixation of a subcondylar fracture of the mandible. A subcondylar fracture of a mandible was simulated by a series of finite element models. These models contained approximately 1.2 million elements, were heterogeneous in bone material properties, and also modeled the muscles of mastication...

BACKGROUND: Forensic investigations have been reported regarding the loss of consciousness and cardiac arrests resulting from direct mandible impact. However, the mechanisms by which the forces are transferred to the skull through direct mandible impact remain unclear. We conducted a study regarding direct mandible impact on the level of energy required to create a mandible fracture and on the energy dispersion phenomenon to the skull and to the brain. MATERIALS AND METHODS: This study combines an experimental and numerical approach...

PURPOSE: The objective of this study was to complete a comprehensive retrospective review of the epidemiology and patterns of injury in mandibular trauma based on the Parkland Memorial Hospital trauma database over a 17-year period. The authors identified 4,143 fractures in 2,828 patients from the databank. In mandibular trauma, the mechanism of injury and several other variables can be an important point of differentiation with regard to fracture pattern. By showing the statistical relation between these and fracture pattern, the authors hope to provide surgeons with a better understanding of such a relation...

Dislocation is defined as the complete loss of articular relationship between the articular fossa of the temporal bone and the condyle-disk complex. Most common aetiology of dislocation is wide mouth opening, trauma and use of certain drugs. It is classified as acute, chronic and recurrent. Chronic recurrent dislocation of mandible is a distressing condition especially for geriatric patients. Various non-surgical methods of reduction include Hippocratic method, Awang's gag reflex method, wrist-pivot technique, combined ipsilateral staggering technique, recumbent approach, intermaxillary fixation, injection of a sclerosing solution, autologus blood transfusion and botulinum toxin...
