Thumb Reconstruction with a Free Neurovascular Wrap / 대한정형외과학회잡지

On the length, strength, free lateral motion, and perfect mobility of the thumb, depends the power of the human hand. The thumb is called pollex because of its strength and that strength is necessary to the power of the hand being equal to that of all the fingers."So stated Sir Chales Bell in the fourth Bridgewater Treatise, first published in 1833. Morrison and O'Brien advocated reconstruction of the thumb with a free wrap around flap from the big toe to recreate a stable, sensate and functional digit including the nail in 1980. From March, 1982 to July, 1988, Twelve thumb reconstructions were performed using the wrap around procedure at Hanyang University Hospital;12 successful thumb reconstructions were reviewed at an average of 16 months after surgery. There were several complications;these included skin necrosis(4), malunion(1), resorption of the bone graft(7). We considered that cosmesis and function were good;pinch grip averaged 68% of normal, sensibility returned in all patients as assessed by two-point discrimination(average 9.5mm). Over all the results are as follows. 1. The wrap around technic provides a good method of reconstruction. 2. The wrap around technic is one stage operation and can be used in the level of metacarpal amputation. 3. The surgeon should be familiar with microsurgical technic.

Aneurysamal Bone Cyst in Pubic Bone: A Case Report / 대한정형외과학회잡지

The pubic bone is an unusual site for an aneurysmal bone cyst. This case, a 15year old male patient, was diagnosed as an aneurysmal bone cyst in the superior ramus of the right pubic bone. He was treated by complete excision of the superior ramus and on five years follow up no problems were noted in terms of weight bearing as well as hip function or evidence of recurrence.

A roentgenocephalometric study of the bony structure and its profile / 대한치과교정학회지

The primary objective of this study was to define the differences that exist. between different sexes on the dentoskeletal framework and the soft tissue profile around the mouth. For the purpose of this study, cephalometric radiographs were obtained from the centric occlusion with closed lip position, through the research on each 42 males and females aged from 17 to 22 years with normal occlusion and acceptable facial appearence. The results were as follows: 1. Maxillary to mandibular relationships. Among the angles formed by the long axis of the maxillary and mandibular anterior teeth, the maxillary and mandibular anterior alveolar bone, and the lower and upper lips (Fig.2), only the angle formed by the lips was more acute in males than in females. The males have a more rounded profile, and the females have a flatter profile in the lower third of the face. The differences is statistically significant for the angle formed by the lips. The fact that the lips have a difference greater than that of teeth or the alveolar bone indicates that the lip position is not entirely due to tooth and bony support. Possibly the thickness of the lips has an influence. 2. Occlusal plane. The occlusal plane was related to the anterior tooth inclination, anterior alveolar bone profile, and the lip contour, both maxillary and mandibular (Fig.3). Only the angle related to lower lip was statistically significant. The females again had the more obtuse angle, indicating a flatter profile than that of the males. 3.Skeletal planes. The angles formed by the anterior maxillary lips, teeth, and alveolar bone with the Frankfort plane and the angles of the mandibular lips, teeth, and, alveolar bone and the mandibular plane were investigated (Fig.4). Results were similar to those from maxillary to mandibular relationships. The results were statistically significant for the upper lip and the lower lip, only. 4. Esthetics. The facial line and the mandibular plane were compared with the esthetic line. These angles were different for the different sexes, but only the latter was statistically significant. This difference may be due to the profile contour of the nose.

Orthodontic consideration of cleft lip and palate (Report 1) / 대한치과교정학회지

The role of the Orthodontist in cleft lip and cleft palate therapy is primarily ill correction of malocclusion which is required by practically every child who has these defects. He can contribute to the assessment of dento-facial growth and development. We may gain the possible limited correction of delayed malocclusion due to cleft lip and palate. The authors have attempted delayed orthodontic treatment of a cleft lip and palate of 12.9 years old girl, who had a cleft lip and palate of surgical closure at 2,3 and 4 years old.

Clinical consideration of Angle's classification Class III malocclusion / 대한치과교정학회지

Class III malocclusions are difficult to treat and take more time than any other types. But if such problems are detected at the earliest opportunity, we may gain the best possible correction consistent with the limitations imposed by morphogenetic pattern. The question of whether a patient has false or real Class III malocclusion is not important. Therapy wilt eleminate the malrelationship, in any event. Graber said, "It has been my experience that many so-called "pseudo" Class III"s are full-blown Class III" s later on during the prolific growth period." The authors have attempted early treatment of a Class III malocclusion of 8-year old girl, who has the familial history of Class III malocclusion.
