Osteochondroma is the one of the most benign tumors of the axial skeleton, but is rarely found in the facial bones. Typical facial features of condylar osteochondroma include striking facial asymmetry, malocclusion with openbite on the affected side, and prognathic deviation of the chin and crossbite to the contralateral side. In this case, twenty four year-old female showed facial asymmetry, chin deviation, openbite on the affected side but have no symptoms of pain or dysfunction. Concomitantly she had maxillary occlusal cant and hemimandibular hypertrophy. Panoramic radiograph showed radiopaque mass on right mandibular condyle extended along the lateral pterygoid muscle. Computed tomogram demonstrated enlarged condylar head and bony spur on posteromedial side of condyle and 99Tc bone scintigraphy showed a focal hot image. These findings were correspond with osteochondroma. The lesion was treated with condylectomy and residual facial asymmetry was corrected with 2-jaw orthognathic surgery. Herein, we report a case of osteochondroma of the mandibular condyle and accompanying facial asymmetry.

Subcutaneous emphysema and pneumomediastium is a relatively uncommon phenomenon. Most case of pneumomediastium are caused by iatrogenic injury on the cervical region and chest during tracheostomy. It is also well known that emphysema may occur secondary to dental treatment using high-speed air turbine handpiece, but there have been few cases of emphysema extended to involving the mediastinum. These complications are reported to occur mainly in patients after dental procedures, in particular during mandibular third molar extraction. Early recognition and conservative treatment of these problems is essential in preventing life-threatening complications such as airway obstruction, mediastinitis, pneumothorax and cardiac failure. As we report a case of 25-year-old woman with subcutaneous emphysema and pneumomediastium after mandibular third molar extraction using high-speed air turbine handpiece.

The purpose of this study was to evaluate the clinical outcomes of patients with temporomandibular joint disorder before and after performance of arthrocentesis and stabilization splint therapy. The subjects of this study were 33 patients with limited mouth opening or pain or joint effusion who visited the Department of Oral and Maxillofacial Surgery, St Mary's Hospital, Catholic University of Korea. The arthrocentesis was performed and the stabilization splint was worn immediately after the arthrocentesis. Comparing the clinical outcomes of treatment at the times of first medical examination, 3 months and 6 months later on treatment. The results are as follows; 1. Statistically significant increase in the amount of maximum mouth opening occurred 3 months and 6 months later on treatment. 2. Statistically significant decrease in the average value of pain on test measured by VAS during maximum mouth opening, protrusive movement, right lateral movement, left lateral movement occured 3 months and 6 months later on treatment. The results suggested that arthrocentesis and stabilization splint therapy provide a improvement on patients with temporomandibular joint disorder when the exact diagnosis were provided.

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.

Intraoperative breakage of instruments can be occurred unexpectedly. To prevent damage of neighboring important anatomic structures and consequent complications, broken instruments should be removed as soon as possible. There have been several methods to remove broken instruments. One of them is the Carm fluoroscopy which is commonly used for locating metal foreign bodies. However, its application for removal of broken instruments in the oral and maxillofacial area is not common. In our experiences with the removal of two broken instruments in mandibular area, the newly developed dental mini C-arm was used to find broken instrument in soft tissue, because it gives real-time in situ information for the intraoperative location. We report two cases with broken instruments, a broken dental needle in the pterygomandibular space and a broken straight bur in the mandibular angle area. They were identified and could be removed safely using a dental mini C-arm.

Tooth impaction represents the stop of eruption by clinical and radiographical disturbance in eruption path or the dislocation of tooth germ. The most common factor in tooth eruption disorders are spacial deficiency with other causes reported to be odontogenic tumors, periodontal ligament injury, etc. Impaction of the mandibular second molar is relatively rare and reported in about 3 out of 1,000 people. Because the second molars tend to erupt in a mesial direction, this situation can lead to serious problems if untreated, including dental caries, periodontal disease and root resorption of the first molar. Treatment of this problem includes, surgical repositioning and orthodontic forced eruption. Because each procedure have the definite advantages and disadvantages, and influenced by circumferential environment, these have limits for successfu1 recovery as independent treatment. In a case at St. Mary's Hospital, we performed successful correction of a horizontal impacted mandibular second molar using a miniplate skeletal anchorage system. We introduce this treatment as a valid method for an impacted second molar and consider a oromaxillofacial surgeon's role in tooth movement treatment.

Implant placement on the anterior mandible is considered a common and safe surgical procedure. However, severe hemorrhage can occur if branches of the sublingual artery, which run through the lingual cortical plate of the mandible, are damaged. Excessive hemorrhage caused by injury to the sublingual artery can result in life-threatening problems such as airway obstruction. A 54-year old male patient without any generalized systemic conditions was referred due to active bleeding after implant placement in the anterior mandible. Gauze compression with surgicel and bosimin were performed and hemostasis was achieved. The patient was discharged after 3 days without any supplementary bleeding.
