Fracture of mandible can be classified according to its anatomical location, in which condylar fracture is the most common one overall and is missed on clinical examination. Due to the unique geometry of the mandible and temporomandibular joint, without treatment the fractures can result in marked pain, dysfunction, and deformity. The condylar fracture may be further classified depending on the sides involved: unilateral/bilateral, depending on the height of fracture: intracapsular (within the head of condyle), extracapsular - head and neck (high condyle fracture), and subcondylar (low condyle fracture), and depending on displacement: nondisplaced, displaced (anteromedially, medially, and lateral), and dislocated...

INTRODUCTION: Subcondylar fractures are common in children. Occlusion disorders resulting from these fractures in deciduous or mixed dentition do not have as much impact as in adults due to alveolar adaption possibilities. Functional treatment allows for good functional results, but does not treat the dynamic shortening of the ramus. The objective of this study was to evaluate the axiographic condylar slope changes after subcondylar fracture in children. MATERIALS AND METHODS: A prospective study was conducted from 2010 to 2015, including all the under-18 patients presenting with a subcondylar fracture...

There are no clearly defined guidelines for when an open or closed treatment is indicated for treatment of mandibular condylar fractures. The aim of the study is to analyze the mandibular function after nonsurgical treatment of unilateral subcondylar fractures, in a prospective study. A prospective study was conducted on 30 patients with unilateral mandibular subcondylar fracture undergoing nonsurgical treatment. Clinical and radiographic examinations were done prior to treatment and at 12-month follow-up. Pain, perceived occlusion, mouth opening, protrusion, and horizontal movements of the mandible were evaluated by clinical examination...

BACKGROUND: To present the outcomes for a case of unilateral mandibular subcondylar fracture with dislocation in an 11-year-old female treated with an acrylic splint for functional repositioning of the mandible. CLINICAL PRESENTATION: A splint was placed in the upper arch to restore the functional repositioning of the mandible. The splint's height was increased up to 5.5 mm on the side of the fracture to stimulate growth on the deficient side. To correct the mandibular asymmetry, a construction bite was made by 4 mm advancing...

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...

BACKGROUND: Although the fractures of the mandibular condylar region are very common, the controversies about the treatment of this area is still ongoing. In recent years, general agreement has emerged that open treatment is more effective than closed approaches for extracapsular condylar fractures. However, this time, the method of surgical approach has become controversial. The aim of this study was to evaluate the effectiveness of the retromandibular transparotid approach for the fixation of subcondylar/high ramus mandible fractures...
