Bilateral Superolateral Dislocation of Intact Mandibular Condyle with Concomitant Symphysis Fracture: A Case Report.

Dislocation of the mandibular condyle of the temporomandibular joint (TMJ) is defined as a clinical condition in which head of the condyle is displaced out of its functional position within the glenoid fossa and posterior slope of the articular eminence Allen and Young in Br J Oral Surg 7:24-30, (1969). Dislocation of the mandibular condyle most commonly occurs in the anterior or anteromedial direction in both traumatic and non-traumatic origin dislocations. Lateral dislocations are generally rare owing to the thickening of the lateral surface of the articular capsule by the lateral ligament that strengthens the lateral surface of the joint Lovely and Copeland in J Can Dent Assoc 47:179-184, (1981).

Preauricular transmasseteric anteroparotid approach for extracorporeal fixation of mandibular condyle fractures.

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.
