Reports of mandibular symphysis widening with distraction osteogenesis / 대한치과교정학회지

Transverse skeletal deficiency is a common clincal problem associated with narrow basal and dentoalveolar bone. The clinical characteristics of transverse deficiency presents with anterior crowding and posterior buccal crossbite. Orthodontic expansion, using lip bumper and functional devices, was recommanded for younger ages. However, expansion of lower anterior area in older patients is unstable and tends to relapse toward the original dimension. Distraction osteogenesis is a unique form of clincal tissue engineering and biologic process of new bone formation between bone segments that are gradually separately by incremental traction. Distraction osteogenesis was considered that great potential for correcting transverse mandibular deficiencies. In this paper, a case of treated transverse deficiency patients with distraction osteogenesis using tooth-borne and tooth & bone-borne distractor is presented.

Soft Tissue Reconstruction Using Peroneal Myocutaneous Island Flap / 대한정형외과학회잡지

The Authors newly designed one of the Myocutaneous Falp modifying the peroneal island flap. This flap involved a part of peroneal muscle and skin on the outer side of leg and pedicle consisting of the peroneal artery and vein as an island flap. It was useful on soft tissue and skin defect of ipsilateral leg or foot region, which area was needed thicker one than simple cutaneous flap. We have treated four patients using this flap and achieved satisfactory results.
