When the midfacial fractures involve the upper maxilla (LeFort I, II, III), there is a chance that the nasolacrimal duck may have been injured. When this suspected, We must observe the presence of epiphora carefully. If the epiphora was not improved following conservative treatment, dacryocystorhinostomy would be the treatment of choice. We performed two cases of DCR and got the favorable results.

투명세포암은 대개 신장, 폐, 갑상선, 인후부 및 타액선 등에서 발생하는 드문 악성종양이다. 타액선에서 발생하는 경우는 아주 드물며, 이하선이나 소타액선에서 간혹 발생된 증례가 보고되고 있다. 저자등은 상악 우측 후방 치조능 부위에 발생한 투명세포암을 경험하였으며, 외과적으로 완전 적출하였으나 술후 18 개월째 사망하였다. 투명세포암의 진단, 감별진단, 치료 및 예후에 관하여 문헌 고찰과 더불어 보고하고자 한다. Clear cell carcinoma arises mainly in the kidneys, thyoid glands, uterus, lung and sweat glands. This tumor is very rare in the salivary glands, but arises mainly in the parotid and minor salivary glands. We experienced a rare case of clear cell carcinoma in the upper right alveolar ridge. This patient died 18 months after wide radical resection. We present the diagnosis, differential diagnosis, treatment and prognosis of clear cell carcinoma with literature review.

Leukemia is a malignancy affecting the WBCs of the bone marrow. Leukemia is classified as either acute or chronic, and classification is essential since there are important differences in response to treatment of the various types of leukemia. The etiology of the leukemia is unknown. For accurate diagnosis, several laboratory studies, including CBC, PBS, BM biopsy, immunophenotyping, chromosome analysis, are necessary. Dentists have become increasingly interested in leukemia, because the oral complications are common throughout the clinical course of the disease, dental management is complex, and the mouth is a potential source of morbidity and mortality. Because oral signs and symptoms are common, the dentist may be the first clinician to suspect the disease. A case of leukemia presenting as facial infection is described with literature review.

Because of the prominence of the nose and its central location, it is the most frequently encountered fractures in the face. Yet reports about the nasal bone fractures are virtually rare in the oral and maxillofacial surgical literatures. This sis a retrospective study on 19 nasal bone fractures treated in Chosun university hospital Department of Oral & Maxillofacial Surgery from Jan. 1991 to Sep. 1993, under admission to our Dept. and the obtained results were as follows. 1. Of the 240 patients with facial bone fractures, 28 patients suffered nasal fractures(12%) and male to female ratio was 5.3:1. 2. The most frequent cause was traffic accidents(39%)m, the next fall down(36%), first blow(4%). 3. The age frequency was the highest in the fifth decade (32%). 4. Clinical classification of nasal fractures was simple fractures(74%), comminuted fractures(26%), and single fractures(37%), combined fractures(63%). 5. The most frequently combined site was msxilla(50%). 6. Treatments of nasal fractures were closed reduction(63%), open reduction(5%), and secondary rhinoplasty(32%). 7. The initial treatment time from accident was 1.7 days in single fractures, and 3.5 days in combined fractures, and the period of splint retained was about 8.2 days in single fracture, about 8.7 in combined fracture. 8. It was necessary to treat secondarily in delayed treatment, and all treatment methods showed relatively good prognosis. 9. Closed reduction was treated under local anesthesia, but open reduction & secondary rhinoplasty was treated under general anesthesia except 1 case. 10. The complications were disturbance of swellings 5 cases, eithetic problem 5 cases, epiphora 3 cases, abnormal sensation 6 cases in relation with other fractures.

Human Dura mater treated by various processes was used to restore small periodontal defects, large bony defects for improvement of new bone formation, and soft tissue defects and replace the disc of TMJ, etc.. Tutoplast Dura is the solvent-preserved Human Dura mater and sterilized by gamma radiation. In our department, Tutoplast Dura was implanted in 32 patients, from 1994, 6 to 1995, 7. We implanted the Tutoplast Dura at 11 various cysts, 6 implantations, 4 fractures, 3 clefts, 2 TMJ disease, 2 maxillary sinusitis, etc.. We performed the retrospective study about the purpose of Tutoplast Dura implantation, postoperative complication and histologic examination of biopsy specimen at implant second surgery.

The authors investigated the 17 patients with the condylar fractures of the mandible who were admitted in Dept. of Oral and Maxillofacial Surgery, Chosun University, Dental hospital from 1990 to 1993 and could be taken follow-up above 6 months. Helkimo's clinical dysfunction index and mandibular mobility index were applied to the evaluation of the patients and the obtained results were as follows. 1. Mean maximal mouth opening was 38.4mm in the conservative group, 41.3mm in the surgical group and that showed no statistically significant difference.(P>0.05) 2. Clinical dysfunction index was higher in the surgical group than in the conservative group but .that showed no statistically difference.(P>0.05) 3. The extent of maximal mouth opening was increased gradually throughout the follow-up period. 4. Both groups didn't show severe clinically dysfunction.
