This study evaluated the results of surgical and conservative treatment of managing simulated unilateral dislocated fractured mandibular condyles. Group A left the fractured condyle in its dislocated position outside the glenoid fossa. Group B consisted of surgical treatment by completely detaching the condyle, then replacing it as free graft and its subsequent fixation with interosseous wiring. Immediate postoperative mandibular function was performed in both groups. In both groups, we performed simulated retrodiscal injury and discal displacement by incision. Clinical, morphologic, functional, radiologic, and histologic examinations were conducted on all animals. We got the following results. 1. There were no functional and morphological deformities in both groups. 2. The radiographic examination showed the good union of fractured line and condylar remodeling at 3 months in both groups. 3. In all experimental period, no inflammatory reaction was observed. In both groups, good condylar remodeling change was observed. The chondroid tissues apperared between the hypertrophic zone and subchondral bone area. None of the condyles were lost as result of necrosis in group B.

북방수염하늘소 유충의 이목 침엽수 종류에 따른 성장과 발육 및 생식
황인천,김주현,박종빈,신상철,정영진,조세열,박용철,Hwang, In-Cheon,Kim, Ju-Huyn,Park, Jong-Bin,Shin, Sang-Chul,Chung, Young-Jin,Cho, Sae-Youll,Park, Yong-Chul 한국응용곤충학회 2008 한국응용곤충학회지 Vol.47 No.4
북방수염하늘소의 유충은 먹이로 공급된 잣나무, 소나무, 젓나무, 일본잎갈나무, 백송, 그리고 리기다소나무 각각을 식이하여 성장할 수 있다. 이목의 종류는 유충의 크기와 생존력에 큰 영향을 준다. 처리구 모두 유충의 성장곡선은 사육 3개월 동안 계속 증가하며, 이 후에는 약간 감소한다. 유충과성충의 크기는 백송에서 가장 크게 나타났다. 다음으로 소나무, 잣나무, 젓나무에서 비슷한 크기로 자랐다. 가장 작은 것은 일본잎갈나무와 리기다소나무를 급여한 것이었다. 유충은 적당한 양의 수분이 공급되어야 성장할 수 있다. 유충에서 생식 활동이 가능한 성충으로 우화할 시기까지 생존율은 잣나무식이구 53.6%, 소나무 51.8%, 젓나무 34.7%, 백송 17.8%, 일본잎갈나무 16.7%, 그리고 리기다소나무 12.3%로 나타났다. 각 처리구에서 우화한 성충은 산란을 하였으며, 알은 부화하여 정상적인 유충으로 성장하였다. 실내 사육(2007년 6월부터)되어 월동시킨 노숙유충의 일부는 용화하지 않고 2008년 10월말 현재까지 유충상태로 남아있다. 야외에서 자연 감염된 잣나무와 일본잎갈나무 각각에서 우화한 성충의 두폭은 암 수 모두 잣나무 개체군이 크게 나타났다. 탈출공의 크기도 잣나무에서 크게 나타났다. 탈출공의 크기는 자연에서의 것보다 먹이 경쟁을 최소화하고 적당량의 수분을 공급한 실내 잣나무 접종목에서 크게 형성되었다. Larvae of Monochamus saltuarius showed normal growth and development on conifers of Pinus koraiensis, P. densiflora, Abies holophylla, Larix leptolepsis, P. bungeana, and P. rigida, respectively, but the conifers influenced significantly the body weight and the survival rate of larvae. Though the larval body weights were in a wide spectrum among treatments, growth curves of them were very similar from each other, showing continuous increase from the early larval stage to about 3 months old. The body weight was decreased slightly after the feeding period of the early 3 months. The size of larvae and adults became the largest from P. bungeana fed larvae. The mid-sized ones were from P. koraiensis, P. densiflora and A. holophylla. Small ones came from L. leptolepsis and P. rigida. The larval growth was retarded without water supply. Overall survival rates from the early stage of a larva to a fertile adult were 53.6% from P. koraiensis; 51.8%, P. densiflora; 34.7%, A. holophylla; 17.8%, P. bungeana; 16.7%, L. leptolepsis; and 12.3%, P. rigida. Adults from larvae fed the 6 species of conifers, respectively, were grown into the reproductively potent adults, which laid viable eggs. A few of overwintered larvae did not pupate and remained still as a larva until the late October of the year. Data from the field survey, the head width emerged from P. koraiensis was larger than that of L. leptolepsis. The adult emergence hole in P. koraiensis was larger also. While, the size of the emergence hole was larger in the artificially innoculated log of P. koraiensis, which was kept for a larva to be with a minimized food competition and sufficient water supply, than that of the field.

특이한 악관절 강직증 : 진성 악관절 강직증과 상악골과 하악골 사이의 골성 유합
서재훈,조세인,여환호,이기혁,김영균 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.2
TMJ ankylosis is classified with true and false type. A true ankylosis is defined as any condition that produces fibrous or bony adhesions between the articular surfaces of the temporomandibular joint. The main causes of true ankylosis are trauma or infection. A false ankylosis results from pathologic conditions outside the joint that limit mobility of the mandible such as myogenic disorders, coronoid impingement or rare direct bony fusion between maxilla and mandible. The treatment of choice of TMJ ankylosis is surgical intervention. We experienced the male patient with complete mouth opening limitation since 45 years before. This patient has true TMJ ankylosis and rare bony synostosis between maxilla and mandible in the right posterior region. We performed surgical intervention and had a favorable result.
