The purpose of this study was to evaluate the result after 2-phase surgical-orthodontic treatment without preoperative orthodontic treatment for the skeletal Cl III malocclusion patient and to obtain an adequate protocol on the bases of this result. This retrospective study of ten patients who underwent 2-phase treatment were done to evaluate 1) the surgical stability and relapse pattern 2) the facial esthetics 3) the TMJ problem 4) the total time of the treatment. Results were followed : 1) The horizontal relapse of the mandible was 26.8% and didn't show significant differences compared to the conventional 3-phase treatment. But, it was considered that this amount of relapse was the sum of true relapse and autoratation of mandible due to decreased vertical dimension during orthodontic treatment. 2) It was estimated that there's no difference on the ratio of anterior facial height between the subjects and the normal patients. On the horizontal analysis, the mandible of the subjects was located more anteriorly than that of the normal patients. This result showed that there was a need for the accurate preoperative esthetic evaluation and the additional methods for reducing the relapse due to the occlusal interference. 3) Wide variation was noted on the TMJ symptoms of the subjects, however, it was estimated that there's no significant differencees of symptoms compared to that of the conventional 3-phase treatment on literatures. 4) The average of the overall period of treatment was 20.8 months and we obtained reduction of the treatment time compaired to 3-phase treatment on many literatures. Most of the results of this study were similar to the findings of the 3-phase treatment(preoperative orthodontic-orthognathic surgery-postoperative orthodontic), but total time of the treatment was shorter in patients with 2-phase treatment than in those with the conventional 3-phase treatment. With 2-phase treatment, we experienced many advantages compared to the conventional method considering that it was favarable conditions for the teeth, it had the flexibility for the treatment, and it could be the adequate treatment approach for the stomatognathic system. Although this retrospective pilot study had some limitations, due to small samples, the authors would hope that it could serve as a guide for the future reaearches, and the clinical applications.

This article describes a new approach in the treatment of skeletal class III malocclusion. This new approach, which means 2 phase treatment without preoperative orthodontics, includes orthognathic surgery first, followed by postoperative orthodontic treatment. A this article together with introduction of a newly modified articulator. Based on this new concept, we have treated more than 30 patients of skeletal class III malocclusion since 1994 and confirmed its advantages over the old method.

A 65 years old woman presented with indurative buccal swelling without ulceration. The result of the incisional biopsy disclosed as "plasmacytoma", and a series of radiographic and laboratory tests were rendered to find out if it involved multiorgan or not. Based on those studies, we finally diagnosed the disease as multiple myeloma and planned surgical excision followed by systemic chemotherapy.

A false aneurysms of the head and neck are rare lesions. Their histologic characteristic is quite different from that of true aneurism in that their wall consists of false endothelial lining only. Until recently their treatment was by a variety of surgical approaches or angiographic embolization. But, because of their aggressive behavior and possible complications, more consevative approach like a sono-guided compression has been sucessfully reported by some authors. The advantages of this method is that it is safe, less aggressive and not complicated procedure. We report a case of false aneurysm of facial artery after BSSRO, which was successfully treated by sono-guided compression.

The purpose of this study was to observe the tissue response to the orthodontic force applied immediately after buccal horizontal subapical osteotomy of maxilla. Five mongrel cats weighing about 2.5 Kg were used for this experiment. The left upper canine and premolar of each cat served as a experimental side and the right ones as a control side. On the experimental side, a 100gm orthodontic force was applied between the upper canine and premolar immediately after the osteotomy. On the control side, the same orthodontic force was applied without the osteotomy. After 7days, the experimental animals were sacrificed. The results were as follows: 1. In the pressure zones of the experimental group, significant increase of osteoclasts and direct resorption along the alveolar bone surface was observed as compared with those of the control group. 2. In the pressure zones of the experimental group, a less extensive hyalinized zone was observed than those of the control group. 3. In the pressure zones of both group, no root resorption was found. 4. In the tension zones of the experimental group, new bone deposition increased along the alveolar bone surface as compared with those of the control group. In conclusion, the results suggest the possibility that early orthodontic treatment after orthognathic surgery may have some benefits if the stability of the repositioned segment at surgery is secured.
