        골 결손 내에 이식한 자가 이개연골 및 연골막에 대한 연구

        권건영,강진성,한기환,오두종 大韓成形外科學會 1992 Archives of Plastic Surgery Vol.19 No.2

        Autogenous bone graft has been the method of choice in bone defect reconstruction. Yet it has the disadvantages of a significant operation time and added morbidity to the patient from the harvesting of bone. Auricular cartilage can be obtained easily under local anesthesia, and a significant portion of th concha can be removed without deforming the coner area. The fate of layered autogenous cartilage-perichondrial grafts into the bone gap was observed in a dog model. Twelve Korean adult dogs underwent surgically induced segmental ostectomies of the body of the mandible. Teeth in the area of the defect were extracted six to eight weeks prior to creation of the defect. The cartilage attached to the perichondrium was obtained from ears, and sectioned into 10 x 10mm slices, and layered with wire fixation. The layered cartilage-perichondrium was grafted into 25mm bone gap that was kept separated with a miniplate and screws. A specimen of 35mm long including host bone was obtained as an en and 24weeks, postoperativly. The specimen was investigated by radiology and sectioned sagittally for hematoxylin-eosin staining. Radiologically, the bone formation ratio to the graft was about 81% and osseous bridge was almost completed at 24 weeks postoperatively. All grafts demonstrated degeneration of cartiage and neocartilage formation between the cartilage and perichondrium. Subsequently, the neocartilage was replaced by the woven bone which in turn was remodelled into lamellar bone. This was substantiated by radiologic examination of the specimen. The potential of cartilage and bone formation of layered autogenous cartilage-perichondrial graft in bony gap was investigated in this experiment so it may provide an alternative to bone graft.

        액취증에 대한 피하지방층 삭제술 중 수공법과 Inaba법의 비교

        오두종,한기환,강진성,송중원 大韓成形外科學會 1992 Archives of Plastic Surgery Vol.19 No.1

        Various surgical methods for the treatment of osmidrosis have been descirbed for many years. Two basic types can be identified : one method that removes skin and subcutaneous tissue altogether : the other method that removes only subcutaneous tissue without removal of skin. The former had problems such as prolonged healing, scar formation, restriction of shoulder movement, and incomplete cure, so the latter has become a better solution in surgical treatment of osmidrosis because it leaves more favorable scars and excellent results. The authors compared the two surgical methods which remove the apocrine and eccrine glands without removal of skin : One is a manual method where two incision lines parallel to skin crease are made in the axilla and the underneath of the skin is removed by scissors, and another is Inaba's method wgere one small incision line is made in the axilla and the underneath of the skin is removed by subcutaneous tissue shaver. Comparative studies were made grossly and microscopically. The authors reviewed 15 patients who were treated by the manual method in right axilla and inaba's method in the left axilla from April 1988 to October 1989. They were 10 females and 5 males with the mean age of 22years. Follow up studies were carried out for at least one and half years up to 3 years after the operation. The results were as follows : 1. The operation time was 14 minutes shorter in Inaba's method. 2. There were no significant differences in hair growth, sweating and histologic findings. 3. The scar was more inconspicuous in Inaba's method than in manual method. 4. All the patients were satisfied with the results : no recurrence of odor, good wound healing and favorable scars. In summary, we have obtained excellent results in both methods but the Inaba's method is simpler and easier, leaves more inconspicuous scar and saves time.
