Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

Fibrous dysplasia is a benign pathologic condition of bone which medullary bone is replaced and disturbed by poorly organized, structually unsound fibro-osseous tissue. When facial bones are involved, considerable esthetic deformity may result. The term monostotic fibrous dysplasia has been applied when one bone is involved : when more than one bone is affected, the term polyostotic used. The polyostotic form may be accomplished by pigmented skin lesion (Jaffe type), or by pigmented skin lesions with endocrine disturbance (Albright syndrome). No general agreement exists on the cause of fibrous dysplasia. A few authors have suggested that fibrous dysplasia as a result of trauma. It occurs predominantly in infant, adolescent females and runs a variable clinical coures. When several bones are involved, it tends to be unilateral. Involvements of alveolar bone may produce displacement of teeth with malocclusion, or loss of teeth, or both. Now, we will present a case of fibrous dysplasia on the left facial region treated by conservative contouring surgery.

An experimental study on gtr technique using lyodura and microfilter in rat s osseous defects
조세인(Se In Cho),여환호(Hwan Ho Yeo),김영균(Young Kyun Kim),임석균(Seok Kyun Lim) 대한구강악안면외과학회 1995 대한구강악안면외과학회지 Vol.21 No.4
구강악안면외과 영역에서 골 결손부에 대한 골재생유도에 관한 많은 연구를 통해 GTR technique에 이용되고 있는 Gore-tex membrane의 생물학적 친화성이나 골 결손부의 재생시 유도능력에 관한 확신올 제공하고 있다. 최근에는 치주치료에 이용되는 GTR과 구분을 위하여 골 조직의 선택적인 재생을 유도한다는 의미로 GBR(Guided bone regeneration)과 osteopromotion이라는 용어가 주로 사용이 되고 있고 협의의 치료개념이 아닌 광범위한 악안면의 결손부의 재건에 응용이 기대되고 있다. 그러나 재료의 값이 비싸고 비흡수성으로 제거가 필요하다는 단점을 갖고 있다. 이에 저자 등운 값이 싸며 흡수성을 갖는 lyodura와 비흡수성의 microfilter를 GTR에 이용하여 Gore-tex membrane을 대치하는 효과를 살펴보고자 하였다. 실험군은 lyodura와 microfilter group으로 나누어 백서의 좌측 하악 우각부에 인위적인 8×8mm의 전층골결손부를 형성하고 각기 lyodura와 microfiliter를 골결손부위에 기개하고 봉합하였으며 반대측은 각 실험군의 대조군으로 골 결손부를 피개하지 않고 방치하였다. 술후 1주, 3주, 5주, 8주 후에 각기 실험동물을 희생시키고 골결손부의 조직학적 검사를 시행하였다. 양 실험군은 대조군에 비해 골결손부에 새로운 골의 형성이 더 많이 되었고, Lyodura 군이 Micro filter꾼에 비하여 골형성이 더 이루어졌다. 본 실혐의 결과로 흡수성의 Lyodura가 GTR technique에 이용되는 Gore-Tex를 대치할 수 있는 매우 유용한 재료로 사료되었다. Many reports confirmed excellent biocompatibility and ability of bony regeneration of e-PTEE (Gore-tex membrane) in the Oral & maxillofacial field. At present, the term「Guided bone regeneration」and osteopromotion are mainly used in the literature for this membrane technique. Biologically membrane coverage of bone defects create a suitable environment for bone regeneration. However, disadvantages of high cost and necessity of membrane removal still remained. Recently, biodegradable membranes have been studied and used The present study was designed to consider the effect of lyodura and microfilter for replacement of Gore-tex membrane in rat s osseous defects. The experimental groups were divided into 2 groups. Group 1 is the lyodura group, Group 2 is the microfilter group. The control group was the contralateral angle defect without membrane coverage. Fullthickness bony defects to expose the marrow 8×8 mm in size were created in the right and left mandible angle of rats, and then lyodura and microfilter were covered on the left side and not covered in the right side as a control. Each group was sacrificed after 1 week, 3 weeks, 5 weeks, and 8 weeks after surgery and histologic examination was performed. Both experimental groups had earlier and more bone formation than the control group. The Lyodura group seemed to have more bone formation than the Microfilter group. These results suggest that Lyodura may be very useful in GTR for replacement of Gore-tex material.

Bilateral cleft lip reconstruction can be performed in one-or two-stages. The choice depends on the surgeon's proficiency and experience. However the type and severity of the cleft must be considered. Complete or incomplete symmetric, bilateral clefts in which the premaxilla is within the alveolar arch or slightly protruded can be successfully treated with simultaneous lip reconstruction on both sides. There are some advantages that one-stage lip reconstruction facilitates creation of a symmetric and balanced lip, retraction of protruding premaxilla and the parent's psychologic satisfaction. However, there are some disadvantages such as micrognathia of the upper jaw by severe scar formation and poor adaptation of flap margins by severe tension. The surgeon must be able to judge and exploit the advantages offered by one-stage approach. We present the case report of one-stage reconstruction of primary bilateral cleft lip with literature reviews.

Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.
