영남대학교 의과대학 부속병원에서 발생한 치골결합 분리증의 빈도는 1:693이며 분리된 정도가 심할수록 증상도 심했고 다른 합병증도 동반되었으며 완전히 회복되기까지의 기간도 길었다. 산모가 임신전 상태로 완전히 회복되기까지의 기간은 지난 후 1개월에서 4개월까지 다양하였는데 분리된 정도와 회복기간의 연장이 반드시 일치하는 것은 아니었다. 이전 임신 시의 치골결합 분리가 다음 임신 시 분만 방법에 영향을 미치기는 하지만 반드시 수술적 요법을 생각해야 하는 것은 아니다. 앞으로 치골결합 분리의 재발 유무와 적절한 상담을 위해 증례 보고를 한 환자들을 계속 추적 관찰할 예정이다.

Background: This study was conducted to determine the effect of the distributional relationship between dental roots and the mandibular bone on single mandibular bone fractures, which are common craniofacial fractures. Methods: This was a retrospective, single-center study in Seoul, Korea. Patients with single mandibular fractures in the symphysis, parasymphysis, body, and angle area, with tooth structure involvement were included. The control group included patients with simple, bone-level lacerations without fractures. In total, 94 patients (72 males and 22 females) were included in the treatment group, and 125 (71 males and 54 females) were included in the control group. The height of the mandibular bone and the dental root were measured with panoramic radiography. The central incisor represented the symphysis area, the canine represented the parasymphysis area, the first molar represented the body area, and the second molar represented the angle area. Results: In the treatment group, symphysis fractures occurred in 16 patients (17%), parasymphysis fractures in 36 patients (38%), body fractures in 17 patients (18%), and angle fractures in 25 patients (27%). The ratios of the dental roots to the total height of the mandibular bone in the treatment group were 30.35%, 39.75%, 39.53%, and 36.27% for symphysis, parasymphysis, body, and angle areas, respectively, whereas in the control group, they were 27.73%, 39.70%, 36.76%, and 35.48%. The ratios of the treatment group were significantly higher than those of the control group. Conclusion: The results show that the higher ratio of the dental root to the height of the mandibular bone increases the fracture risk.

저자 등은 1996년 1월부터 2004년 12월까지 서울대학교 보라매병원 구강악안면외과에서 치료받은 141명의 하악골 골절 환자의 임상적 연구를 통하여 다음을 알 수 있었다. 1. 전체 환자에서 남,녀 성별 발생빈도는 5.13대 1로 남자에서 호발 하였으며, 연령대별로는 20대에서 가장 빈발하였고 (30.5%), 그 다음 30대, 40대 (22.7%) 순이었다. 2. 하악골 골절의 원인으로 폭행 (45.4%), 낙상, 추락 및 충돌 (40.4%), 교통사고 (11.3%) 순이었다. 3. 골절부의 위치는 하악 정중부 (41.2%), 우각부(32.2%), 과두부 골절(18.5%)의 순으로 나타났으며, 단일 골절의 경우 하악 우각부 골절이 (46.7%)로 가장 많았고, 두 군데 이상의 골절의 하악 정중부 및 우각부 동시 골절이 가장 많았다 (45.5%). 4. 교통사고로 인한 하악 골절은 정중부, 과두부, 우각부 골절의 순으로 발생 빈도를 보였고, 폭력과 낙상, 추락 및 충돌 등으로 인한 골절의 경우 정중부, 우각부, 과두부 골절 순으로 발생빈도를 보였다.

Lateral and superior-lateral dislocations of the intact condyle are a rare complication, following traumatic insult to the mandible. We report an unusual case of a 54-year-old male patient who experienced both types of dislocations of the intact condyles with symphysis fracture following a road-traffic accident. Under general anesthesia, conventional manipulation was unsuccessful in relocating the condyles into the glenoid fossa. After applying a percutaneous traction force, using a bone traction hook placed at the sigmoid notch, the displaced intact mandibular condyles were repositioned, and the symphyseal fracture was finally reduced and fixed. The mouth opening was within normal limits, and favorable occlusion was confirmed one month postoperatively. To our knowledge, this is the first case of dislocation of both intact condyles--associated with symphysis fracture--being reduced with bone traction hook.

Skeletal Class III malocclusion is a relatively common form of malocclusion in Korea. In borderline cases where only mild skeletal discrepancy exists and if worsening of the facial profile is expected as a result of premolar extraction, mandibular full arch distalization with miniscrews is the treatment of choice. The purpose of this study was to investigate the pattern of tooth movement and evaluate the stability of mandibular full arch distalization and to identify correlation between stability and factors such as initial skeletal pattern, dental changes during treatment and alveolar bone in symphysis region using lateral cephalograms.

Objectives: We compared resorbable plates with titanium plates for treatment of combined mandibular angle and symphyseal fractures. Materials and Methods: Patients with mandibular angle and symphysis fractures were divided into two groups. The control (T) group received titanium plates while the experimental (R) group received resorbable plates. All procedures were carried out under general anesthesia using standard surgical techniques. We compared the frequency of wound dehiscence, development of infection, malocclusion, malunion, screw breakage, and any other technical difficulties between the two groups. Results: Thirteen patients were included in the R group, where 39 resorbable plates were applied. The T group consisted of 16 patients who received 48 titanium plates. The mean age in the R and T groups was 28.29 and 24.23 years, respectively. Primary healing of the fractured mandible was obtained in all patients in both groups. Postoperative complications were minor and transient. Moreover, there were no significant differences in the rates of various complications between the two groups. Breakage of 3 screws during the perioperative period was seen in the R group, while no screws or plates were broken in the T group. Conclusion: Resorbable plates can be used to stabilize combined mandibular angle and symphysis fractures.

Objectives: The aim of this study was to compare morbidities and duration of surgery, as well as bone formation in alveolar defects reconstructed with symphysis bone combined with allograft and iliac crest bone graft in patients with cleft palate. Patients and Methods: This randomized clinical trial was performed with 22 patients with unilateral alveolar cleft with a follow-up period of 12 months. In 12 patients, alveolar defects were reconstructed with chin bone graft plus allograft (Group A), while for the other 10 patients, iliac bone crest was used as donor site (Group B). Duration of surgery as well as occurrence of morbidities and complications were recorded. In addition, cone-beam computed tomographic (CBCT) scans were performed before surgery and 12 months after surgical procedures in order to compare bone formation between the two groups. Results: Postoperative CBCT demonstrated a mean bone fill percentage of 76.9% of the alveolar defect in Group A, compared with 77.0% in Group B. Paresthesia in the lower lip or chin did not occur in any patients of Group A. The mean duration of the surgical process was significantly shorter for Group A (40 minutes vs 76 minutes, P<0.001). In addition, patients in Group A regained normal gait faster than patients in Group B (1 day vs 9.5 days). Conclusion: Mandibular symphysis bone graft in combination with allograft results in favorable outcomes in patients with unilateral alveolar clefts.
