The results of radiographic study of healing of fractured mandible are often inconsistent with clinical evaluation of bone healing pattern of it. In addition, there is inconsistency between radiographic studies. We think if such inconsistency is resolved, clinical assessment combined with radiologic evidence can be used to guide to more accurate clinical management. The purpose of this study is to evaluate radiological healing pattern of mandible, and to apply its result to clinical use. Panoramic view was used to analyze the change of radiographic finding in 35 patients (27 male, 8 female, ranging 17 to 53 years old) treated for mandibular fracture at the department of oral & maxillofacial surgery, SNUH in the period 1991 to 1998, Patients are all treated by rigid internal fixation using monocortical miniplate. Within 9 weeks, no change is observed at fracture site. Osteogenic change is observed at various time interval (3 to 21 weeks). We have found radiographic change of healing is observed 4 to 6 weeks later to clinical healing, According to this result, we recommend radiographic follow-up at 4 week, 10 week, 10 month.

융비술시 실리콘 고무는 다루기 쉽고 조직 반응이 적어 현대 많이 돌출의 합병증이 생길 수 있다. 저자등은 이러한 실리콘의 단점을 보완할 수 있는 goretex를 사용하여 융비술을 시행하고 비첨에 대해서 자가연골을 이식하여 만족할 만한 결과를 얻었기에 goretex가 안면부 연조직의 증강을 위한 이식재료로 적합하다고 생각되어 문헌고찰과 함께 보고하는 바이다. Many different materials have been used to provide augmentation of the nasal dorsum. this include both autogenous and homogenous materials,as well as allografts. Silicone among the artificial materials has been most widely used. The silicone has some advantages and disadvantages. Goretex(expanded polytetra-fluoroethylene) which has widely used in vascular surgery and abdominal surgery can be used for facial soft tissue augmentation. The author presemts 2 cases of nasal augmentaion using goretex with literature review.

In the head and neck area, there are so many sensory nerves, which are sometimes injuried iatrogenically or inadvertently so that involved patients complained of the loss of sensations. In such cases, it is important to judge the degree of injuries and regeneration of nerve for better diagnosis and treatment. Seddon and Sunderland's classification, which is commomly used, is focused on histological change and nerve conduction. As times goes by, it is difficult to access patient's sensory disturbance by this method. Until now, so many methods such as contract threshold, direction, two-point discrimination, pin prick, thermal discrimination and current perception threshold have been introduced for sensory evaluation. However, there hasn't been enough information regarding each methodology nor integrated standard methodology for the measurement. the purpose of this study is to get Korean adult normative sensory values of lower lip,chin and tongue using modified methods of contact thershold, ditection, two point discrimination, pin prick, thermal discrimination and assess degree of regeneration of sensory nerve damage.

The surgery of oral and maxillofacial area poses the risk of cranial nerve damage such as trigeminal nerve or facial nerve. Inferior alveolar nerve is prone to damage in the third molar extraction, implant installation, orthognathic surgery, open reduction and rigid fixation, and tumor ablation surgery. On the other hands,facial nerve is likely to be damaged or sacrificed with trauma or parotidectomy. In case of inferior alveolar nerve injury, the incidence is reported to be about 1.3%. The nerve function will almost recover in minimal damage, but it won't recover at last in total damage of a part of nerve unit. In latter cases, nerve regeneration in intended by allograft as nerve substitute or various route of merve condit. But the recovery with autograft is believed to be most relialbe mrthod in the rapair of long-span(longer than 15㎜)nerve defect. We have performed autologous sural nerve graft in the repair of nerve defect, which is caused by resection of benign or malignant tumor. Hereby we report the method of nerve harvesting, recovery of defected peripheral nerve and the complications of donor site with the discussion of sural nerve anatomy.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

In a study of 20 cases have been investigated clinically and radiologically long term results (6 months and over) of the sagittal split osteotomy technique (Obwegeser - Dal Pont 1961). The overall relapse rate was 30% but reoperation is not required. A statistical analysis of cephalometric radiographs was done and possible causes of relapse was discussed. The results were as following. 1. There are 6 cases of relapse in 20 patients (30%). 2. There are significant correlationship between amount of setback and long term horizontal relapse (p<0.01). 3. There are significant correlationship between surgical change of mandibular plane angle and long term horizontal relapse(p<0.01). 4. The direction and amount of vertical changes are irregular and there are no statistical correlationship. 5. The duration of fixation and patients age at operation are not correlated to horizontal relapse. 6. In preoperative cephalometric measurements, mandibular plane angle and gonial angle are not correlated with horizontal relapse. 7. Wire osteosynthesis is inadequate comparing rigid fixation in the aspect of positional stability.

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.

환경문제가 심각해지며, 환경교육에 대한 중요성이 강조되고 있으나 대학교육에서는 환경교육은 활발히 이루 어지고 있지 않다. 대학에서의 환경교육은 환경공학 중심으로 이루어지고 있는데, 공학교육의 일환으로써의 환경교육 은 환경공학에서의 학문분야뿐만 아닌 공과대학생 전체에 적합한 환경교육이 이루어져야만 더욱 큰 효과가 있을 것 이다. 본 연구에서는 공과대학생을 위한 환경교육을 위하여 공학교육과 환경교육 전문가의 의견을 반영한 AHP 기법 을 적용하여 공학도에게 적합한 환경교육 범주를 선정하였다. 공학도를 위한 환경교육범주를 선정한 후 공과대학생을 대상으로 환경교육을 실시하였으며 교육전후의 인식변화 설문조사를 통한 교육전후의 환경에 대한 인식변화를 통계 적으로 검증하였고 추가적으로 친환경제품의 구매 데이터를 기반으로 통계적 분석 및 RFM 분석을 실시하여 환경교 육의 실질적 성과분석을 수행하였다. The environmental education is more and more important according to increasing environmental problems, but university students don't receive it actively. Actually, environmental education in university is conducted and focused on environmental engineering. In order to have an effect on environmental education for all engineering college students, the course of environmental education consists of various fields of engineering study including environmental engineering. The environmental education categories for engineering college students are determined by using an AHP technique in this study. After educating engineering college students with the developed environmental education course, we evaluated the environmental education performance using the survey on perception level and purchasing data of environmentally consciously products by statistical and RFM analysis.
