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.

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.

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.

Inselecting scars for treatment, attention be paid not only to the features of the defect as seen objectively but also to the element of the defect most distubring to the paitent. We revised the scar tissues with simple elliptical excision, Z-plsty, modified Z-plasty, W-plasty and hand dermabrasion in varialbe pattern of scrs and got the favorable results. The success rate of scar revision usually depends on the paitent's usbjective judgement. We must inform our patient the limitation of scar revision and importance of postoperative care. The oral and maxillofacial surgeons must resolve the variable scars which re involved in varialbe operations and traumas.

A wide variety of deformities can occur following repair of the cleft lip. Especially, cleft lip nasal deformities offer the severe psychologic, esthetic, and functional impairment. We must restore the deformities of alar cartilge, nasal tip, septum, columella, or pyriform aperture. The authors reconstructed the cleft lip nasal deformities using with the alar cartilage rearrangement, postauricular cartilage graft, and/or columellar lengthening. The 3 case reports are presented.

The purpose of this study is to evaluate whether the ashed tooth powder is utilized as an alternative material of the implant. For this purpose the author performed the experimental study to investigate the tissue response of sintered toothash and its histocompatibility. Bony defects to expose the body of marrow, $1{\times}1cm$ in size, were created in the right and left mandibular body of mature dog, and then the ashed tooth powders were filled in right side and the blood clot was filled in the left side as an control. The dogs were sacrificed at 4th, 7th, and 16th week after implantation and histologic examination was performed. The results of this study were obtained as follows : 1. Any inflammatory response was not noted after implanting of the ashed tooth powder during the whole experimental period. 2. At 4th week, ashed tooth powders were surrounded by mature connective tissue. And we could observe hydroxyapatite crystal structure within the ashed tooth powder. 3. At 7th week, we could observe that macrophage phagocyted the small granules of ashed tooth powders. 4. At 16th week, the union with host bone by growth of new trabeculae was observed. And there were remnants of ashed tooth power within some of new trabeculae.
