INTRODUCTION: In a condylar fracture whether to intervene or to go for conservative management still remains a dilemma. Studies and hypothesis suggests that it's medially dislocated condylar fracture segment that is more likely to ankylose, moreover no consensus have been put forth as to whether to remove the medially displaced fracture segment. PRESENTATION OF CASE: The current article describes a case of unilateral temporomandibular joint (TMJ) ankylosis, which resulted as a sequlae from conservative management of a bilateral condylar fracture of which, the ankylosed side had a sagittal fracture of condyle...

PURPOSE: To analyze the biomechanical healing process on rigid fixation of sagittal fracture of the mandibular condyle (SFMC), and to provide guidelines for surgical treatment. METHODS: Three-dimensional finite element model (3D-FEAM) of mandible and condyle was established. The right condyle was simulated as SFMC with 0.1 mm space across the condyle length ways. The 3D-FEAM of rigid fixation was established. The biomechanical factors such as stress distribution of condylar surface, displacement around fracture, stress on the plate and stress shielding were calculated during 0, 4, 8 and 12-week after rigid fixation...

UNLABELLED: Bilateral mandibular condylar fractures accounts for 24% to 33% of condylar fractures but the indications of open reduction of bilateral condylar fracture are still controversial. It is generally accepted that displaced subcondylar fractures are indicated for open reduction, but the proper treatment of condylar head fractures are still variable. This retrospective study compares the radiographical and functional outcomes of bilateral condylar head fractures between open and closed reduction groups...

The anatomically and functionally complex nature of the temporomandibularjoint (TMJ) makes its reconstruction one of the most challenging tasks faced by surgeons who operate in the head and neck. TMJ prosthesis is one of the important techniques in the reconstruction of TMJ. The main indications for TMJ prosthesis include ankylosis, fractures of condylar that can't be fixed, trauma or tumor, end-stage TMJ disturbance, and TMJ dysplasia caused by Hallermann-Streiff syndrome. TMJ replacement aims to enhance the function of TMJ, alleviate pain, and prevent serious complications...

Two children (11 year old) with bilateral condylar fractures associated with symphysis fracture were conservatively treated. Both of them were followed up for about 1 year. A review of 21 cases of bilateral condylar fracture available in the literature revealed the younger the patient, the better the outcome of TMJ function or in radiographic remodeling. However, the longer the time elapsed, the higher the incidence of remodeling deformity and dysfunction. Thus, it must be better that a close follow-up of bilateral condylar fracture in children should be continued until the end of growth period...

The current article describes a case of a patient with temporomandibular joint (TMJ) ankylosis undergoing surgery performed with a tailored technique for condylar reshaping. A patient with posttraumatic bilateral TMJ ankylosis underwent interpositional arthroplasty with temporalis fascia, and focus was put on the need to maintain the vertical height of the mandible. The postoperative course was uneventful, and positive outcomes were kept during a 1-year follow-up span. The adoption of surgical strategies aiming at restoring a condylar shape as similar as possible to the natural one may be important in the light of the search for surgeries providing and/or recreating normal function of the TMJ...

We investigated the incidence of ankylosis of the temporomandibular joint (TMJ) after open operations for fractures of the mandibular condyle, and analysed possible risk factors in a total of 385 patients with 492 condylar fractures who had been operated on in our department from 2001 to 2010. Sixteen patients developed postoperative ankylosis of the TMJ with 26 joints (5%) affected during a follow-up of 6 months-10 years. Of the 492 condylar fractures, the most common ones that were associated with postoperative ankylosis were those of the condylar head (20/248), followed by the condylar neck (6/193)...
