Most fractures of the mandible can be managed conservatively. This report is a retrospective evaluation of the clinical and radiological results in 17 patients with 21 dislocated fractures submitted to open reduction and fixation, employing steel wires and maxillomandibular fixation. Follow-up ranged from 7 to 55 months, (mean 29.5). Functional assessment showed good opening movements (mean 41.9 mm). There were no cases of ankylosis, pain, or paralysis of the facial nerve. Radiological assessment was normal when the lateral pterygoid muscle was maintained adherent to the fractured proximal segment. Radiological signs of bone resorption occurred when the fractured segment was detached from the lateral pterygoid muscle. In our opinion, dislocated condylar process fractures can be managed surgically and with steel wire ligatures and maxillomandibular fixation. Whenever possible, the lateral pterygoid muscle should be inserted into the fractured proximal segment, i.e. as an osteomuscular flap.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009068 Movement The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior. Movements
D011626 Pterygoid Muscles Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side.
