Purpose: The nasal bone fracture is known as the most common facial fracture. Several authors reported the classification of nasal bone fracture. Stranc classified the type of nasal fractures based on a pattern of impaction and level of injuries. Stranc classification proposed here is based on careful clinical observation and relates to both treatment and prognosis. The aim of this study is to determine any predictive value to the preoperative classification of nasal fracture, using the description by Stranc and Robertson. Methods: We reviewed 310 patients with nasal bone fracture treated at our hospital for last two years. Results: Lateral impact type of nasal bone fracture predominated more than frontal impact in the ratio of 2.3:1. The most common type of Stranc classification was lateral impact plane I(48.4%). Male predominated more than female in the ratio of 3:1. The most frequent age group was first decade(27.1%), second decade in frontal impact(30.5%), first decade in lateral impact (30.7%). The most common etiology was violence (31.3%) followed by slip down(21.3%), and traffic accident(18.1 %).The most common associated fracture was orbital(22.9%) followed by zygoma(10%), and maxilla (6.1%). The most common complication was septal deviation(20.0%) in frontal impact, and nasal deformity (26.0%) in lateral impact. The incidence of nasal deformity in lateral impact(26.0%) was more higher than frontal impact(15.8%) Conclusion: By assessing the pathomechanics and resultant degree of injury to the nasal skeleton, a better understanding of the treatment plan and prognosis was obtained. Using this information, satisfactory informed patient consent can be obtained.

During the period of 4 years from August 1, 1975 to August 1, 1979, authors have experienced 100 cases of multiple rib fractures by nonpenetrating injury at Department of Thoracic Surgery, Paik Foundation Hospital in Seoul, Korea. 1. The ratio of male to female patients with multiple rib fracture was 2.6:1 with male predominance and 84% of the total cases were between 20 and 50 years of age. 2. The most common cause of multiple rib fracture was traffic accident and falls accounted for the next largest group. 3. The most common site of rib fracture was 4th rib to 7th rib level on both hemithorax [52%]. 4. Associated injuries were cerebral contusion in 26%, clavicular fracture in 22%, long bone fracture in 22%, pelvic bone fracture in 10%, and scapular fracture in 8%. 5. Early complications and/or result of the multiple rib fractures were lung contusion in 23 cases, subcutaneous emphysema in 21 cases, hemothorax in 21 cases, hemopneumothorax in 6 cases, and flail chest in 12 cases. 6. The flail chests were managed by strapping the chest with adhesive plaster, external traction of flail segment with towel clip, ventilatory assistance for marginal clinical indications, and in cases of complicated with intrathoracic hemorrhage, wire fixation of flail segment through open thoraco-tomy. 7. The principles of therapy for hemothorax and/or pneumothorax were rapid reexpansion of the lungs by thoracentesis [11%] and closed thoracostomy [22%], but open thoracotomy had to be done on 3 cases because of massive bleeding or intrapleural hematoma and diaphragmatic rupture. 8. The over all mortality was 4% [4 among 100 cases] and the cause of all deaths was head injury.

최근 집중호우, 잦은 강설, 급격한 기온차이 등 환경변화의 가속화에 따라 균열, 단차, 포트홀 등 다양한 형태의 도로 파손이 급증하고 있다. 이중 포트홀 관련 사고는 파손 특징상 대형사고를 유발하며 08년 기준 5년간 약 5배 이상 증가하였다. 매년 포트홀로 인한 인명피해, 차량파손 등 직 간접적인 피해가 증가함에 따라 보다 신속하고 효율적인 관리 대책이 필요하다. 따라서 본 연구에서는 포트홀 규모, 면적과의 상관관계를 통해 체적 보정계수와 보수재료 물량산출 알고리즘을 제시하였다. 제시된 물량산출 알고리즘의 검증을 위해 수도권 지역 15개소의 포트홀을 측정한 결과 통상적으로 개소당 약 5~7 kg까지 발생하던 재료 잔량이 1~2 kg까지 감소하는 것으로 나타났다. 작업자의 주관적인 판단에 의존하여 시공하고 있는 실정에서 포트홀 체적 감지 자동화 통합시스템은 재료/자원 절감뿐 아니라 적정한 보수물량 산정을 통해 다짐상태 등 포장 품질향상에 기여할 수 있을 것이다.

감각 및 운동 이상 증상을 동반하면서 꾀병이 의심되는 환자를 가려내는 방법에 대해서 약술하고 몇 개의 증례를 예시하였다. 꾀병을 규명하기 위해서는 우선 전환 장애, 가장성 장애를 차례로 증명하여 제외시켜야 한다. 이를 위한 방법으로는 자세한 병력 수집과 조사, 면밀한 신경학적 검사, 심리검사, 장시간의 면담 그리고 광범위한 행동 관찰이 필요하다. 그러나 증상 형성의 동기나 의도의 본질을 파악하기란 어려워서 환자의 고백에 의해 알게되는 경우도 있다. 신경 심리검사를 포함한 임상심리 검사를 통하여 꾀병의 가능성을 가려내고, 질병행동 특성을 파악하거나 기계적인 측정도구를 이용하기도 한다. 그러나 아직 객관적으로 타당한 검사 방법은 부족하다. 최근, 통증 차단제를 이용한 진성(眞性) 통증 구별법은 객관적인 검사법의 하나이다. 사고나 보상 문제가 겹친 만성 통증 환자는 꾀병의 가능성이 엿보인다 하더라도 많은 수에서 시간 경과와 환경의 영향으로 인해서 정신사회적 합병증을 동반한다. 향후 임상 심리검사법이 발달되고 행동과 의도성에 관한 뇌 기능의 연구론 통해 신체 증상이나 행위의 진실성에 대한 구별력은 더욱 향상될 것이다.

Background: An independent medical examination (IME) is a critical process for awarding reparation for injury. However, conducting an IME in pain medicine is very difficult, not only because pain is a subjective symptom, but also because there are no proper objective methods to demonstrate it. This study was conducted to compare IME reports and the court decisions on the disability status of the patients. Methods: We analyzed 79 IME reports and 25 corresponding court decisions on the disability status of patients. The diagnoses, causal relationships between the patients' status and the trauma, McBride's degree of disability, the American Medical Association's impairment ratings, the estimated annual cost for future treatment, and the necessity of care-giving were compared and analyzed. Results: The diagnoses in the 79 cases were complex regional pain syndrome (CRPS) type I (58 cases), CRPS type II (7 cases), peripheral neuropathy (5 cases), myofascial pain syndrome (4 cases), herniated intervertebral disc (2 cases), and fibromyalgia (1 case). The types of accidents were road traffic accidents (50 cases), military injuries (14 cases), industrial accidents (11 cases), and others (4 cases). The IME reports and the court decisions stated considerably different McBride's degrees of disability (P = 0.014). However, there was no significant difference in the estimated cost for future treatment between the IME reports and the court decisions (P = 0.912). Conclusions: IME reports should be accurate, fair, and based on objective findings. Feedback on IMEs from the court decisions is helpful for reference use.

Objective : Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. Methods : Nineteen consecutive patients who underwent single-stage reconstruction with titanium mesh for FCCD of the skull from April 2014 to June 2018 were retrospectively analyzed. The demographic and radiological characteristics of the patients with FCCD were investigated. The characteristics associated with surgery and outcome were also evaluated. Results : The frequency of TBI in men (94.7%) was significantly higher than that in women. Most FCCDs (73.7%) occurred during work, the rest were caused by traffic accidents. The mean interval between TBI and surgery was 7.0±3.9 hours. The median Glasgow coma scale score was 15 (range, 8-15) at admission and 15 (range, 10-15) at discharge. FCCD was frequently located in the frontal (57.9%) and parietal (31.6%) bones than in other regions. Of the patients with FCCDs in the frontal bone, 62.5% had paranasal sinus injury. There were five patients with fractures of orbital bone, and they were easily reconstructed using titanium mesh. These patients were cosmetically satisfied. Postoperatively, antibiotics were used for an average of 12.6 days. The mean hospital stay was 17.6±7.5 days (range, 8-33). There was no postoperative seizure or complications, such as infection. Conclusion : Immediate bony fragments replacement and reconstruction with reconstruction titanium mesh for FCCD did not increase infectious sequelae, even though FCCD involved sinus. This suggests that immediate single-stage reconstruction with titanium mesh for FCCD is a suitable surgical option with potential benefits in terms of cost-effectiveness, safety, and cosmetic and psychological outcomes.

Purpose: Fractures of the mandibular condylar area are common injuries that account for 29% to 40% of fractures of the facial bones and represent 20% to 62% of all mandibular fractures. Currently 3 main methods are being used in the treatment of mandibular subcondylar fractures: closed reduction; open reduction and internal fixation; Endoscopic reduction and internal fixation. Each method has its proponents and opponent as well as advantages and disadvantages, and indications for each vary among surgeons. There are six approaches of open reduction: submandibular, retromandibular, preaurilcular, postauricular, intraoral, transparotid approach. Among them, transparotid approach has been described for subcondylar exposure with dissection in the direction of facial nerve fibers to expose the bone through the parotid gland. This approach carries the risk of a parotid glandular fistula as well as facial nerve injury but has the advantage of being directly over the fracture site. We report safety and efficacy of surgical treatment using a transparotid approach for direct plating. Methods: A 43-year-old man sustained multiple facial bone fractures by driver traffic accident. Mandibular subcondyle was fractured and dislocated internally. We performed open reduction and internal fixation by transparotid approach. Fractured site was fixed by titanium mini plate & screw. We applicated arch bar for approximately 3 weeks. Results: Follow-up length was about 5months. Scar of surgical incision was indistinct, there was no symptoms and signs of facial nerve and parotid gland injury, and maximal mouth opening was measured 49.5 mm. Conclusion: Transparotid approach has high risks of facial nerve and parotid gland injury, but paradoxically it is the most effective technique in saving facial nerve. Open reduction and internal fixation of mandibular subcondylar fracture by transparotid approach with precise and versed procedure, best outcome can be expected.
