The Orbital fracture which is often combined with midface fracture can cause decreased visual acuity, limitation of eyeball movement, diplopia, enophthalmos, etc. Traumatic orbital fracture causes change of orbital volume, results in diplopia and enophthalmos thus, accurate repositioning of displaced bone and reconstruction of orbital defect with autogenous materials(cranial, rib, iliac bone, cartilage and fascia lata) or alloplastic materials(gelatin film, polyglactin mesh, methylmethacrylate, Teflon, silicone, Supermid, hydroxyapatite and metal). The key point of reconstruction of orbit is accurate repositioning of displaced orbital floor, lateral, medial orbital wall and sufficient bonegraft in anatomical defect. As this cases, we obtained good results through transconjunctival and coronal approach who were required orbital reconstruction. Also, we accurately diagnosed orbital fracture with C.T., 3D model and good result for orbital reconstruction with sufficient parietal block bone graft during average 16.8 months follow-up.

Skeletal class III malocclusion with aterior deep bite is difficult to manage properly, especially in case of mild mandibular prognathism. We have designed lower anterior segmental osteotomy for improving the lower third of the facial contour. Considerable improvement of esthetic facial contour with correction of cross bite in anterior incisors was observed in patients with mandibular prognathism.

In recent decade, there has been a very rapid development in technical possibilities to provide patients with maxillofacial prostheses. Dr. Brenemark first introduced possibility of use of maxillofacial interosseous implant in patients with ablative tumor surgery in 1979. He did introduce the new type of maxillofacial implants system which widen the fixture flange on top of the bone. The advantages of fixed prostheses with implants were well known to various ways, easy to attach, keep clean prostheses, and not to disturb recipient bed. But there are some problems to install implants on maxillofacial regions, because mostly facial bone has very thin cortical bone and poor bone quality. It needs more retention between implant and bone which overcome that fault with fixture flange. To make maxillofacial prostheses, it should be understood general procedure of maxillofacial laboratory work. Ear and midface maxillofacial fabrication which include nose and eye defects will be described step by step.

This is clinico-statistical & retrospective study of 30 patients with only unilateral mandibular condyle fracture and combined with 24 midface fracture patients who were treated with open reduction in Wonkwang University Dental Hospital during the period 1993 to 2000. The results were as follows : 1. In mandibular condyle fracture combined with midface fracture, the most incident type is associated with zygomaticomaxillary complex fracture and level Ⅳ of mandibular condyle fracture combined with ZMC fracture is the most related(33.32%). 2. In the period of intermaxillary fixation, unilateral mandibular condyle fracture group (9.8 days) is shorter than combined with midface fracture group (15.3 days), but no statistical difference between two groups(p.>0.05). 3. In the mouth opening recovery, unilateral mandibular condyle fracture group is faster than combined with midface fracture group in post-operative 1 month, but no significant difference between two-groups after 3 months postoperatively (p>0.05). 4. In two-groups, treatment method is almost open reduction with internal fixation(ORIF) and overall 25% temporary complications were shown, but little lower incidence in unilateral condylar fracture group.

The jaws of children differ from those of adults in the aspects of architectural and mechanical properties, sites, form and treatment modality. This study reviews the result of treatment of pediatric mandibular fractures between 1994 and 1998 at dept. of Oral & Maxillofacial Surgery, School of dentistry, Wonkwang University by means of the age and sex distribution, mechanism of injury, location of fractures and associated patterns, fracture management, postoperative complications, any associated injuries to other organ systems. Total number of these study was 61 facial bone fractures in 32 patients. The results were as follows. 1.The pediatric mandibular fractures predominated in the age of 6∼12, and had no sexual predilection. 2.The main cause of pediatric mandibular fractures was the traffic related accidents(56.2%) 3.The condylar fracture only was 23 cases (37.7%) in total 61 sites of mandibular fractures and the symphysis fracture was 20 (32.7%) ; the highest incidence of mandibualr fracture was the symphysis with unilateral condyle combined fracture in 61 total mandibular fracture sites. 4.The major postoperative complication was deviation during mouth opening (41.2%) and the facial asymmetry(17.7%) in second. 5.Soft tissue laceration(53%) was the most associated injury with mandibular fracture and the abdominal injury(12.5%), the head injury(12.5%), and the extrimity injury (6.2%) in order.
Pediatric Vascular Surgery Review with a 30-Year-Experience in a Tertiary Referral Center
민승기,조성신,김현영,김상준 대한혈관외과학회 2017 Vascular Specialist International Vol.33 No.2
Pediatric vascular disease is rare, and remains a big challenge to vascular surgeons. In contrast to adults, surgery for pediatric vascular disease is complicated by issues related to small size, future growth, and availability of suitable vascular conduit. During the last 30 years, 131 major vascular operations were performed in a tertiary referral center, Seoul National University Hospital, including aortoiliac aneurysm, acute or chronic arterial occlusion, renovascular hypertension, portal venous hypertension, trauma, tumor invasion to major abdominal vessels, and others. Herein we review on the important pediatric vascular diseases and share our clinical experiences on these rare diseases.
