CASES OF THE SURGICAL CORRECTION OF FACIAL ASYMMERY
허홍열,민승기,조상기,정인원,Huh, Hong Yell,Min, Sung Ki,Cho, Sang Ki,Jeong, In Won Korean Association of Maxillofacial Plastic and Re 1991 Maxillofacial Plastic Reconstructive Surgery Vol.13 No.2
안모비대칭은 심미적 정서적으로 영향을 줄 뿐만 아니라 기능적인 장애를 초래하는 경우도 있다. 안모비대칭은 안면골 중에서 특히 하악골과 관련된 경우가 많은데 이는 하악골이 안면하부의 연조직을 지지하므로 작은 위치, 형태 변화에도 두드러지게 나타나기 때문이다. 비대칭안모를 초래하는 하악과두의 거대증은 Hyperplasia, Hypertrophy, 골증, 외골증, 골연골증, 연골육종 등을 들 수 있다. 비대칭안모 분류는 여러 학자에 의해 다양하게 분류되지만 Bruce와 Hayward는 Deviation prognathism, Unilateral macroganthia, Unilateral condylar hyperpiasia로 분류한 바 있다. 과증식된 하악과두의 절제술은 1856년 Humphry에 의해 최초로 시행된 후 여러 학자들에 의해 성공적으로 시행되고 있다. 본 증례에서는 Unilateral condylar hyperlpasia와 골연골종으로 인한 안모비대칭 환자로써 Condylectomy, Le Fort I osteotomy, Vertical ramus osteotomy, Mandibular inferior border ostectomy, Genioplasty 등을 시행하여 심미적 기능적으로 양호한 결과를 얻었기에 이를 보고하는 바이다. This is a case report and review of literature of the facial asymmetry corrected by various surgical methods. In case 1, facial asymmetry resulted from osteochondroma of condyle and corrected via condylectomy only. In case 2, unilateral condylar hyperplasia with compensatory maxillary growth resulted in severe facial asymmetry. Procedures used in case 2 are vertical ramus osteotomy, condylectomy, genioplasty, mandibular inferior border ostectomy and Le Fort I osteotomy.

가토 하악골 결손부에 Dense Hydroxylapatite Block 과 Porous Polyethylene 의 이식후 치유과정에 관한 비교 실험적 연구

N/A This study compared the response of surrounding tissue and new bone formation after PHDPE and HAP block graft in rabbit mandible. The experimental method consisted of making artificial defects (4mmx6mm) in the inferior border of rabbit mandible, inserting PHDPE and HAP block in defect area. The histologic examination was revealed as follows. l. One week after grafting, blood clot, fibroblast and mild inflammatory reaction were observed, but foreign body reaction was not found in both group. 2. Two weeks after grafting, new bone formation started in PHDPE pore near host bone and in host bone adjacent to HAP block. Fibroblast was proliferated in both group. 3. Four weeks after grafting, new bone formation was more apparent in both group. Newly formed bone of HAP block graft group showed more maturity than that of PHDPE graft group. 4. Eight weeks after grafting, new bone formation area of both group showed lamellated structure. In HAP block graft group, direct bony union between HAP surface and newly formed bone was revealed partially and haversian canal was observed. In PHDPE graft group, pore was almost completely filled with newly formed bone.

We had treated 63 cases with cleft lip and palate which visited Department of Oral & Maxillofacial surgery, college of Dentistry, Chon Buk National University from May 1981 to April 1986. In total 63 cases, male patients were 41 cases (65.1%) and female patients were 22 cases (34.9%) Cleft lip and palate patients were 31 cases (49.2%) cleft palate patients were 14 cases (22.2%) and cleft lip patients were 18 cases (28.6%) We performed cheiloplasty by means of Millard s method, LeMesurier s method, Veau s method, Tennison s method and Bauer s method, palatorrhaphy by means of Von Langenbeck method and V-Y retroposition procedure.

Healing process of fresh autogenous iliac bone (as a control group) and Particulated Cancellous Bone & Marrow, Frozen bone, Autoclaved bone grafting, PHDPE and HAP block graft in to the inferior border of the mandible were observed histologically in rabbits. Results 1. One week after grafting, new bone formation was formed in walls of medullary cavity near the cut end of both the host and grafted bone. Coagulation nets, inflammatory cell infiltration, the proliferation of fibroblast was found. Vascularization to medullary cavity of the grafted bone started. In case of PCBM graft group was found osteoclastic activity only. In case of alloplastic grafts, blood clot, fibroblast and mild inflammatory reaction were observed. 2. Two weeks after grafting, new bone formation was apparent in outer surface and cut end of host bone and the grafted bone. New bone formation occurred earlier in the PCBM graft group than in block bone graft. In case of alloplastic graft, new bone formation started in PHDPE pore near host bone and in host bone adjacent to HAP block. Fibroblast was proliferated in both group. 3. Four weeks after grafting of block bone and PCBM, widened haversian canal was partially observed. And new bone formation, started on the host bone, and bony union between host and graft was complete four weeks after transplantation. New bone formation area of frozen autogenous bone graft was more wide than that of frozen autogenous bone graft was more wide than that of autoclaved bone graft. In case of alloplastic graft, new bone formation was more apparent in both group. Newly formed bone of HAP block graft group showed more maturity than that of PHDPE graft group. 4. Grafted bone into mandibular defect area is gradually resorbed and replaced by new bone from at second or fourth week. In HAP block graft group, direct bony union between HAP surface and newly formed bone was revealed partially and haversian canal was observed. In PHDPE graft group, pore was almost completely filled with newly formed bone.

The velopharyngeal mechanism has been described as a valve whose actions serve to separate the oral & nasal section of the upper airway. Velopharyngeal incompetence is the result of abnormal velopharyngeal mechanism. Goal in surgical correction of VPI is to achieve a functional closure of the nasopharynx during the production of single words and connected speech. We had treated 6 cases with VPI which visited dept. of oral & Maxillofacial surgery, college of Dentistry, Chon Buk National University from January 1986 to October 1986. We performed pharyngoplasty using superiooly based pharyngeal flap and inferiorly based pharyngeal flap.

There is a special relationship between the teeth and the alveolar bone. Edentulous patients frequently present a severe atrophic mandibular ridge. Patients with less than 15㎜ of bone in the molar region of the mandible deserve conside ration for bone augmentation. In the visor osteotomy, the bone used to increase mandibular height is a vital graft of basal mandible since it has a soft tissue pedicle. Thus, it may be more resistant to resorption than free bone grafts used in other techniques. We treated patient with severe atrophic mandible via a simul taneous visor osteotomy and Kazanjian vestibuloplasty.
