Cleidocranial dysplasia is rare inherited skeletal dysplasia. It was first reported by Martin in 1765. Subsequently, Marie and Sainton independently documented the criteria of the disease. Cleidocranial dysplasia is a bone disorder caused by a defect in the CBFA1 gene of chromosome 6p21. This gene guides osteoblastic differentiation and appropriate bone formation. Patient with cleidocranial dysplasia has maxillary deficiency, high and narrow palate, prolonged retention of primary teeth, unerupted permanent teeth and supernumerary teeth. Therapeutic options in these patients include of autotransplantation of selected impacted teeth, forced eruption of permanent teeth, full denture, overdenture and implant-supported prosthesis. We report a patient with cleidocranial dysplasia. This patient was treated with implant supported bar overdenture. Despite of gene defect that affects osteoblastic activity, bone remodeling and osseointegration occurred in our patient. So, we report this case with review of literature.

Purpose: Adipose tissue is located beneath the skin, around internal organs, and in the bone marrow in humans. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. Adipose tissue also has the ability to dynamically expand and shrink throughout the life of an adult. Recently, it has been shown that adipose tissue contains a population of adult multipotent mesenchymal stem cells and endothelial progenitor cells that, in cell culture conditions, have extensive proliferative capacity and are able to differentiate into several lineages, including, osteogenic, chondrogenic, endothelial cells, and myogenic lineages. Materials and Methods: This study focused on endothelial cell culture from the adipose tissue. Adipose tissues were harvested from buccal fat pad during bilateral sagittal split ramus osteotomy for surgical correction of mandibular prognathism. The tissues were treated with 0.075% type I collagenase. The samples were neutralized with DMEM/and centrifuged for 10 min at 2,400 rpm. The pellet was treated with 3 volume of RBC lysis buffer and filtered through a 100 ${\mu}m$ nylon cell strainer. The filtered cells were centrifuged for 10 min at 2,400 rpm. The cells were further cultured in the endothelial cell culture medium (EGM-2, Cambrex, Walkersville, Md., USA) supplemented with 10% fetal bovine serum, human EGF, human VEGF, human insulin-like growth factor-1, human FGF-$\beta$, heparin, ascorbic acid and hydrocortisone at a density of $1{\times}10^5$ cells/well in a 24-well plate. Low positivity of endothelial cell markers, such as CD31 and CD146, was observed during early passage of cells. Results: Increase of CD146 positivity was observed in passage 5 to 7 adipose tissue-derived cells. However, CD44, representative mesenchymal stem cell marker, was also strongly expressed. CD146 sorted adipose tissue-derived cells was cultured using immuno-magnetic beads. Magnetic labeling with 100 ${\mu}l$ microbeads per 108 cells was performed for 30 minutes at $4^{\circ}C$ a using CD146 direct cell isolation kit. Magnetic separation was carried out and a separator under a biological hood. Aliquous of CD146+ sorted cells were evaluated for purity by flow cytometry. Sorted cells were 96.04% positivity for CD146. And then tube formation was examined. These CD146 sorted adipose tissue-derived cells formed tube-like structures on Matrigel. Conclusion: These results suggest that adipose tissue-derived cells are endothelial cells. With the fabrication of the vascularized scaffold construct, novel approaches could be developed to enhance the engineered scaffold by the addition of adipose tissue-derived endothelial cells and periosteal-derived osteoblastic cells to promote bone growth.
Midfacial degloving approach를 이용한 중안면 골절 환자의 치험례

In 1974, Casson et. al. reported midfacial degloving approach to repair the midfacial bone fracture. After then, this approach has been used frequently to treat the lesions on nasal cavity, nasopharynx, facial plastic surgery and midfacial trauma. Midfacial degloving approach consists of 1) bilateral sublabial incision 2) complete transfixion incision/ septocolumellar incision 3) bilateral intercartilaginous incision 4) bilateral pyriform aperature incision. This approach provides proper access for midfacial bone structure without facial scar but has post-operative complications such as transient epistaxis, infraorbital nerve paresthesia and nasal crust. We treated three patients using midfacial degloving approach to correct traumatic deformity in midface area. In two patients, rhinoplasty with autogenous rib graft was done simultaneously. So we report these cases with review of literatures.
