  • The present study was performed to establish the cephalometric norms and to study characteristics of craniofacial skeleton of Korean male and female with normal occlusion. The author studied and analyzed statistically vertical cephalometric measurements of the 52 adult male ranging in age from 18 to 26 years and 43 adult female ranging in age from 16 to 30 years with normal occlusion and acceptable profile. The results were as follows; 1. Cephalometric craniofacial norms and standard deviation chart were abtained about adult Korean male and female with normal occlusion. 2. Vertical dimensions of the craniofacial skeleton were larger in male than in female. 3. Lower face was more divergent in female than in male. 4. In simple correlation coefficients between vertical linear mesurements in male and female, high correlation were shown between ATFH and ALFH, PTFH and PLFH, ALFH and ALDH, PLFH and PLDH.

  • It is important to investigate the growth aspects of craniofacial skeleton in the orthodontics. The purpose of this study is to find the factors, which have a great influence on the growth aspects of craniofacial skeleton, and to evalute the control values of each factor in order to construct orthodontics diagnostic and planning.

  • This study was performed to establish the cephalometric standards and to observe the nature of anatomic fit in the internal structural relationship of the craniofaciodental complex of the normal Korean by means of Moyers' method. Lateral cephalograms of 143 males and 144 females with normal occlusion and acceptable profile from 6 to 25 years of age, which were consisted of 5 groups that were 6 year-, 9 year-, 12 year-, 15 year- and adult-group were obtained. Data were gathered by traced digitizing the cephalograms and were statistically analyzed. The findings can be summerized as follows. 1. Norms of Korean males, females and both sexes in each group were established. 2. There was little significant sexual dimorphism in the form of craniofacial skeleton of all age groups. 3. The height and length of craniofacial skeleton was alike in each sexes in the 6 year-, 9 year- and 12 year-group, whereas it was larger in male than in female in the 15 year- and adult-group. 4. There were no significant sexual differences in the internal structural relationship of the craniofacial skeleton in all age groups.

  • Upon analyzing the literature, it becomes apparent that norms for orthodontic diagnosis were from normal occlusion with pleasing face, and that the form and size of craniofacial skeleton were different between racial or ethnic groups. Therefore, this study was intended to establish Korean adult norms be useful for diagnosing the cases and to compare those to other ethnic or racial groups. Lateral cephalometric radiographs were taken of ninety-one Korean adults with normal occlusion showing pleasing face consisted in forty-three males and forty-eight females. The subjects ranged in age from seventeen to twenty-six years. The tracings involved measurements that were analyzed with a digitizer. The findings of this study can be summarized as follows, 1. Norms of Korean adult males, females, and combined sexes were established. 2 It was found that in the form and shape of craniofacial skeleton, there were no significant differences between males and females, but in the size males were larger than females 3. There were a great variation between ethnic or racial groups in the measurements of craniofacial skeleton 4 The size of Korean cranial base was smaller than the American Caucasian. 5 The maxilla and mandible of Korean were less protruded than those of the other ethnic groups 6 The dental pattern of Korean were more proclined than that of the American Caucasian and less protruded than that of the American Negro and the North Indian.

  • Purpose: For the best possible aesthetic reconstruction after craniofacial bone tumor resection, pasteurization has been adopted to devitalize neoplastic cells while maintaining osteoinductive properties and mechanical strength. This case report aims to demonstrate a long-term follow-up result of a monostotic fibrous dysplasia in frontal bone which was reconstructed by pasteurized tumoral autograft in situ. Methods: A 14-year-old girl presented with a hard, nontender, slowly growing mass of 6-year duration on her left supraorbital area. CT showed $5{\times}4{\times}3cm$ sized well defined bony mass confined to frontal bone with heterogeneous density. Tumor was excised completely through bicoronal approach and reimplanted to its original site after pasteurization at $60^{\circ}C$ for 30 minutes. The pathologic examination confirmed fibrous dysplasia. Results: She revisited our clinic 5 years later after suffering some assault on her face. On CT examination, pasteurized tumoral autograft was incorporated to host bone except the fractured upper orbital rim without any evidence of recurrence. She has been satisfied with the result. Conclusion: Pasteurization offers a simple, reliable, cosmetic, economic, and durable reconstruction method for craniofacial skeletal tumor. It has advantages of both biologic incorporation ability and mechanical strength without risk of recurrence. So, it should be considered as one of the primary options in benign as well as resectable malignant tumors of craniofacial skeleton.

  • The configuration of mandibular symphysis is likely to be dependent upon the genetic predeterminants and/or compensatory adjustments onto functional demands. The interrelation of morphological distinctives of symphysis in conjunction to the craniofacial skeleton had been scarcely anecdotal, therefore, the objective was to determine the correlation of morphological modifications between the mandibular symphysis and craniofacial complex. Lateral cephalometric headfilms of 212 subjects were employed for the conventional measurements. The proportion of chin height against chin depth length was referred as chin ratio, then, Low Symphysis (IS) and High Symphysis (HS) groups were turned out by means of the chin ratio. These samples yielded 35 in LS and 35 in HS groups. The data per capita were statistically analyzed and the following results were drawn ; 1. Overall characteristics of the craniofacial skeleton in HS group manifested hyperdivergence and LS group showed hypodivergence. 2. Gonial angle increased as chin ratio increased and was highly correlated to the chin ratio. 3. The chin ratio presented high correlation to the vertical face height, especially in terms of the chin height to anterior face height and the chin depth to posterior face height. 4. The morphological configuration of chin was hardly correlated with hyoid bone position.

  • Superior orbital fissure syndrome is characterized by ophthalmoplegia, ptosis of the eye, reflex dilation of the pupil, and anesthesia of the upper eyelid and forehead. This syndrome may be the result of craniofacial fractures as well as neoplasms of the retrobulbar space, hematomas in the orbital muscle cone and retrobulbar space, and hematoma and infection of the cavernous sinus. A case of superior orbital fissure syndrome is described.

  • Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the "lines of weakness". According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton. Le Fort fractures result in both a cosmetic and a functional deficit if treated inappropriately. In this article, authors review the management of a Le Fort I fracture with a case-based discussion.

  • Purpose : The purpose of this study was to present the clinical features of a case series of osteomas in the craniofacial region and to compare them with those described in the dental literatures. Materials and Methods : A retrospective study of 18 patients diagnosed with osteomas in the craniofacial region was performed. The age, gender, location, symptoms, and the radiological findings were recorded. Results : There were 13 women and 5 men from 18 years to 69 years of age (mean age, $42{\pm}27$ years). Fourteen osteomas were found in the mandible (78%), two in frontal sinus, one in sphenoid bone, and one in maxilla. Conclusion : Osteomas are benign tumors composed of mature compact bone or cancellous bone. They are essentially restricted to the craniofacial skeleton and rarely, if ever, are diagnosed in other bones.
