The purpose of this study was to assess the influence of the presence and impacted state of the mandibular third molars on the incidence of mandibular condyle fracture. A retrospective study was designed for patients presenting to the Department of Oral and Maxillofacial Surgery, Kyungpook National University Hospital and Tae-gu Fatima Hospital for treatment of mandibular fractures from January 2003 to January 2006. The independent variables in this study were the presence, degree of impaction of third molars, and the outcome variables were the incidence of mandibular condyle fractures. Hospital charts and panoramic radiographs were used to determine and classify these variables. The demographic data included age, sex, mechanisms of injuries and number of mandibular condyle fractures. The study sample comprised 136 mandibular condyle fractures in 105 patients. Result of this study demonstrated a statistically significant difference in ipsilateral condyle fractures and mandibular third molar absence(P=0.032) and bilateral condyle fractures without another fracture and mandibular third molar absence(P=0.028).

Today, with the development of modern civilization, the change of industrial structure and the increase of traffic volume and population make the number of maxillofacial injury patients also increase. Especially, the fracture possibilities of mandibular condyle have been increased because of mandibular position and shape. I experienced the case that mandibular condyle fracture caused by gun-shot injury(Bullet had been packed at the opposite condyle of input site) was treated by foreign body removal and condyle open reduction. I will represent that case with the journal review.

This is to report functional treatment, as mechano-therapy, of condylar fracture in cases of growing patients. Benoist's appliance was used in 3 cases condylar fractures, provides extraoral elastic forces to external pterygoid muscle. The appliance providing guided exercise of masticatory muscles induces transformative growth of trauma-tic condyles. The results were as follow; 1. Early exercise preventes ankylosis of fractured condyle. 2. Optimal physical exercise therapy induces the normal growth pattern by muscular training and bony remodeling of fractured condyle in children.

Treatment of condylar fracture is still controversial, but the indication of surgical mangement is increased due to improved fixation methods and surgical techniques. In this article, we report our clinical and radiological results with the use of lag screw osteosynthesis for fixation of fractured mandibular condyle. 12 case of condyle fracture treated by open reduction and fixation with lag screw were monitored for an average of 10 months (range from 6 months to 19 months) postoperatively. The obtained results are as follows : 1. Postoperative maximum mouth opening is achieved over 40mm except one patient. 2. Although slight crepitus and deviation of mandible during mouth opening were found, Temporomandibular joint problem is satisfactory in all but one patient. 3. Distal migration of screw and resorption of fractured fragment were found in each 2 patients, but good functional recovery was achieved in all. According to the above results, we think that lag screw osteosynthesis is relatively indicated in level III or IV condylar fracture.

Frey syndrome is a disease characterized by abnormal sweating, facial redness, and rare pain by stimulation of taste sense on the limited area dominated by the auriculotemporal nerve and great auricular nerve. Although the developmental mechanism and histopathologic cause of Frey syndrome are still being debated, the most reliable theory is based on injury of the parathympathetic nerve connected to the auriculotemporal nerve continuing to abnormal regeneration. The other theory is that the sweat glands develop an increased sensitivity after degeneration of sympathetic fibers. Therapy of Frey syndrome includes drugs, radiographic treatment, and surgical treatment; however, in most cases, treatment is not satisfactory. This is a case report on a 24-year-old male patient with Frey syndrome caused by the fracture reduction with retromandibular approach after multiple facial traumas and spontaneous healing without any special treatment.

The authors investigated the 17 patients with the condylar fractures of the mandible who were admitted in Dept. of Oral and Maxillofacial Surgery, Chosun University, Dental hospital from 1990 to 1993 and could be taken follow-up above 6 months. Helkimo's clinical dysfunction index and mandibular mobility index were applied to the evaluation of the patients and the obtained results were as follows. 1. Mean maximal mouth opening was 38.4 mm in the conservative group, 41.3 mm in the surgical group and that showed no statistically significant difference.(P>0.05) 2. Clinical dysfunction index was higher in the surgical group than in the conservative group but .that showed no statistically difference.(P>0.05) 3. The extent of maximal mouth opening was increased gradually throughout the follow-up period. 4. Both groups didn't show severe clinically dysfunction.

The mandibular condyle fracture occurs at 15-30% frequency of whole mandibular fracture. The treatment of choice is open reduction or closed reduction. In many cases, closed reduction is preferred for treatment of condylar fracture because it is hard to approach to condyle and there is risk of surgical complications, such as nerve damage in open reduction. Open reduction, however, has some advantages like possibility of anatomical reduction, occlusal stability and rapid functional recovery. Furthermore, it is possible to retain original ramal heights and to decrease deviation during mouth opening. There are many surgical approaches for open reduction of subcondyle fracture. At present, transoral approach using trochar device is tried for effective and minimally invasive method for open reduction of subcondyle fracture. And the authors report the cases of reduction of subcondyle fracture with transoral approach using trochar device.

The management of mandibular condylar fractures in children has long been a matter of controversy. The fracture, if not treated appropriately, may result in complications such as disturbance of mandibular growth and temporomandibular joint ankylosis. They are usually treated nonsurgically, which has been proved to be satisfactory in the long term results. Nineteen children with 25 condylar fractures experienced during their growth period (age at trauma from 10 months to 12 years, mean 7.0 years) were studied. All patients were treated by arch bars and intermaxillary fixation for $7{\sim}14$ days. They have been evaluated with clinical and radiographic examination. The maximum mouth opening and lateral movement of the mandible were within normal limits. There was no malocclusion or ankylosis. Beginning of remodelling was evident at postoperative $1{\sim}3$ months. Remodelling of the condyle was good in 21, while partial adjustment occured in the other 4 condyles. These results suggest that the conservative treatment of condylar fractures in growing children results in good functional results and good remodelling of the condyle.

There are some methods of approach to the temporomandibular joint. The preauricular, the endaural and the postauricular incision are frequently used among those. The preauricular incision necessiates a preauricular scar, possible postopertive facial nerve damage and is the least cosmetically desirable incision. The endaural incision is more esthetic than preauricular incision, but it is not sufficient. The postauricular approach allows adequate exposure with decreased occurence of injury to facial nerve and excellent cosmetic results. The purpose of this report is to discuss the surgical approach of postauricular incision to the cases of TMJ ankyloses, internal derangement and condylar fracture of mandible.

Of all facial fractures in children, condylar fractures have the greatest propensity to produce a growth disturbance. This risk appears to be greatest when the injury is during the first 3 years of during adolescence. Yet, the ability of a child to undergo compensatory growth that decrease the effects of the injury is also the greatest. Fracture dislocation of the condyle in the preadolescent often results in excellent remodeling and function. Because of this factor and the higher risRs of avascular necrosis and ankylosis open reduction of a condylar fracture in a child is not widely recommended. This retrospective study analyzed mandibular condyle fractures in the children who admitted in dept. of Oral and Maxillofacial Surgery, Pusan paik hospital from 1984 to 1993 clinically and radiologically.
