개에서 임프란트 주위 골결손부의 수복에 골형성 단백질이 미치는 영향

The porpose of this study was to evaluate the effect of the bone matrix gelatin and bone morphogenetic protein on amount and shape of regenerating new bone adjacent to implant. Implants were placed in canine mandible at 2 months after teeth extraction. Artificial bone defects 3㎜ in diameter and 4㎜ in depth were performed at the mesial and distal side of implant. The mesial defect was filled with the bone matrix gelatin, and the distal defect with the bone morphogenetic protein. The animals were sacrified at 1, 3, 5, and 10 weeks after implantation for light microscopic evaluation. Although there were differences in degree between bone matrix gelatin and bone morphogenetic protein, bone regenerating activities were observed in all defect sites. Bone morphogenetic protein had a more excellent bone forming activity than bone matrix gelatin in the repair of the bone defects. Compared with bone morphogenetic protein group, downward growth of fibrous connective tissue was observed in bone matrix gelation group, and bone level of bone matrix gelatin group was lower than that of bone morphogenetic protein group. Above results suggest that success rate of implant was increased when bone morphogenetic protein was implanted to the bony defects by immediate implantation after tooth extraction or in space between implant fixture and bone tissue, and also bone morphogenetic protein could be applied in reconstruction of bone defects caused by diseases or trauma.

우측 협부의 종창과 압통을 주소로 내원한 59세의 여자 환자에서 방사선 소견상 우측 상악골의 광범위한 골파괴상이 나타났고 조직생검에서 MFH로 진단되었다. 치료는 술전과 술후에 SWOG외 CY-VA-DIC요법을 변형시킨 화학요법과 총 40Gy의 $^{60}Co$ 방사선요법 그리고 우측 상악골전적출술의 삼자병용요법을 시행하였다. 술후 2년이 경과된 현재까지 재발이나 전이 등의 소경은 관찰되지 않고 있으며 환자의 예후에 대하여 주의 깊은 관찰을 계속하고 있다. Malignant fibrous histiocytoma rarely occurs in the jaws. A case of malignant fibrous histiocytoma originated from the maxillary sinus is reported with review of literature. A 59-year-old woman visited the Chonnam University Hospital in March, 1990, with chief complaint of swelling and tenderness in the right cheek. Radiographic findings revealed wide destruction of the maxilla. The biopsy taken from the maxilla showed histopatholgic findings of malignant fibrous histiocytoma. Accordingly the patient received preoperative and postoperative anticancer chemotherapy by the modified CY-VA-DIC protocol of the Southwest Oncology Group (SWOG). Preoperative and postoperative radiotherapy were also given to her in total 40Gy of $^{60}Co$ And she underwent radical resection of the maxilla. No evidence of recurrence or metastasis was shown for 2-year period of postoperative follow up.

유리 늑골-늑연골 복합이식술을 이용한 하악지 및 하악과두 재건

Various surgical technique have been used for the reconstruction of temporomandibular joint. During the past several years, conventional(nonvascularized) costochondral bone graft has been employed most successfully because of its anatomical similarity and functional capabilities of the condyle and costal cartilage. But the conventional costochondral bone graft has limitation in poor recipient site combined with large soft tissue and bone defect. With the advent of microsurgery, vascularized bone graft has proven invaluable. In this report of a case, we discuss the surgical technique and anatomy of free vascularized myoosteochondral rib graft. The result confirms that it is a successful and sound method for reconstruction of temporomandibular joint.

The fibula was investigated as a donor site for free flap mandibular reconstruction. We have found many advantages of fibular flap over the others when used for mandibular reconstruction. It had the advantages of consistent shape, ample length, distant location to allow a two-team approach, and low donor-site morbidity. The fibular graft could be tailored to fit even major mandibular defect using wedge osteotomy. And, the fibular transplant was considered ideal for the insertion of implants to supports dental suprastructures to obtain maximal oral rehabilitation. We have used fibular graft in two cases for secondary reconstruction of left hemimandibular defect resulted from ablation surgery of squamous cell carcinoma. At least two osteotomies were performed on each graft, and miniplates were used for fixation. The results have been most encouraging with respect to function and cosmetic appearance. There have been no transplant failures and minimal donorsite morbidity.

We analysed the clinical datas obtained from 10 patients who underwent reconstructive microsurgery using venous autografts(male, 9 : female, 1 : range of age, 18-70 years old). The autologous veins were used to lengthen the pedicle in 6 cases. In the rest 4 cases, we used the autologous veins to reconstruct the defect of radial artery, lacrimal canaliculi, Wharton s duct and to guide the nerve regeneration, respectively. A length of long(7 cases) or small(3 cases) saphenous veins were harvested. Various types of venous graft with long saphenous vein and its branches(Medial femoral vein and external pudendal vein) were designed, including Y-, Loop- and interpositioning-type. These designs were very helpful when there were inadequate pedicle length, unsuitable recipient vessels. We could observe the patency in the repaired Wharton s duct and lacrimal canaliculi with good salivation and lacrimal drainage. Sensory was restored with the venous tubular guide. In conlusion, venous autografting was most reliable(success rate 90%) and useful technique that might be used in the field of oral and maxillofacial surgery.
