Influence of nasal bone fracture and its reduction on the airway.

Studies regarding nasal bone fractures have mainly focused on esthetic aspects, but the nose also plays an important role as an airway. The purpose of this study was to evaluate the influence of nasal bone fractures and the treatment of nasal bone fractures on nasal obstruction. Nasal bone fractures were classified by fracture site and septal displacement.

Effect of human bone marrow stromal cell allograft on proliferation and collagen synthesis of diabetic fibroblasts in vitro.

In previous pilot studies, the authors reported that bone marrow stromal cells (BSCs) have a superior effect on healing of acute wounds compared with fibroblasts in vitro and in vivo. The present study was designed to compare the effect of allograft of normal BSCs with that of normal fibroblasts on the activity of diabetic fibroblasts in vitro. Diabetic fibroblasts were cultured in 24-well culture plates.

Corrective osteotomy technique for a posttraumatic deviated nose.

Posttraumatic nasal deformities may not be adequately corrected by conventional osteotomy techniques when the configuration of the nasal bone has been changed as a result of malunion. The purpose of this study is to present an osteotomy technique, including refracture along malunion sites and anatomic reduction of a malformed nasal bone, for the correction of a posttraumatic deviated nose. From March 2003 to May 2004, 27 patients, who underwent corrective rhinoplasty for the correction of bony pyramid deviation, were included in this study.

Midface augmentation using bony segments obtained from sagittal splitting angle ostectomy in asians.

Background: Asians characteristically have flat or broad and round facial features. These characteristics are primarily attributable to enlarged and widened jawbones, impressive muscles associated with mastication, and a zygomatic arch involving the masseter. Their faces appear flat, with midface regression in the center.

The effect of human bone marrow stromal cells and dermal fibroblasts on angiogenesis.

Background: A cell therapy methodology for angiogenesis using fibroblasts has already been developed. Bone marrow stromal cells, which contain mesenchymal stem cells, have a low rate of immunity-assisted rejection and are capable of expanding profoundly in culture. Therefore, these cells offer several advantages for transplantation over mature cells.
