Biennial serial cephalometric radiographs of 47 children (26 boys, 21 girls) were used to analyze the craniofacial growth changes in Korean children from 8 years to 16 years of age. A craniofacial model was designed for this study. It consisted of 72 anatomical points and 98 derived points. The craniofacial changes of these samples during these ages might be summarized as follows: 1. Mandibular growth to cranial base was more forward than maxillary growth. 2. Mandibular growth during this period was found to be a forward-upward (bite closing) rotation of the mandible. 3. Growth changes in total mandibular length (Ar-Gn) showed a pubertal growth spurt at 12-14 years of age in boys and 10-12 years of age in girls. Synchrony of the growth spurts on total mandibular length (Ar-Gn) and standing body height was found. 4. The pubertal spurts occured in the growth of total cranial base (Ba-Na) at 10-12 years of age in boys and 8-10 years of age in girls. The time of the spurts of the cranial base growth was 2 years ahead of that of the total mandibular growth. 5. Synchrony of growth spurts in anterior facial height (Na-Me), posterior facial height (S-Go) and body height was found. 6. The whole craniofacial changes during this period were plotted by using a X-Y plotter and personal computer. A simple profilogram for an diagnostic tool was obtained.

The purposee of this study is to investigate the correlation between the horizontal and vertical discrepancy of facial bones and the horizontal and vertical position of glenoid fossa. For this study, the cephalograms were taken to the adults over 18 of age(96 men and 108women). The cephalograms were divided into three groups according to the ANB angle(below 0.5 degree, 0.5 to 4.0 degree and above 38 degree), and they were divided into three groups according to the SN-MP angle(below 30 degree, 30 to 38 degree and above 38 degree). The following conclusions were obtained : 1. In the horizontal discrepancy of facial bone(ANB), the horiontal position of glenoid fossa(X) was anterior position as the order of Class II, Class I, Cias III. 2. The horizontal position of glenoid fossa(X) showed the significant correlation with ANB and SNB, but not with SNA. 3. In the vertical discrepancy of facial bone(SN-MP), thee less anglee was the greater vertical position of glenoid fossa (X) and was followed by the medium and high angle in order. 4. The vertical position of glenoid fossa(Y) showed thhat the SN-FH was the most significant correlation, and it was followed as the order of SN-FH, SN-MP and SN-OP angle. 5. There was the samllest length of anterior cranial base in the Class III malocclusion.

Patients with maxillectomy defects predisposed to not only difficulty in deglutition, mastication, speech but also psychological depression from impaired facial esthetics that affect life quality. Obturator prostheses play a important role in restoring the lost form, function and the quality of life for patients with maxillectomy defects. This clinical report presents the simplified approach to predict the degree of adequate facial support by Artificial palate which reflected from a maxillary interim obturator during the stabilization period after maxillectomy.

In Fibrous dysplasia(FD) of the jaws, the majority of cases can await the cessation of growth before surgical intervention, and it seems prudent to delay surgery whenever possible until growth has ceased. In craniofacial FD, however, the dangers of dystopia, dystopia and loss of vision may require early surgery to prevent or control cranio-orbital complications. Delaying surgery in those circumstances may be significantly detrimental to such patients. Conservative surgical management of FD is widely practised and we advocate an extension to this conservative treatment by combining surgical recontouring with appropriate osteotomies if indicated, to achieve an optimal esthetic and functional results in craniofacial FD. One case will be presented to illustrate the feasiblility of such combined treatment, to report the uneventful healing of osteotomies in the FD of the jaws, and to demonstrate the use of titanium miniplate fixation in dysplastic bone. The other case had expansile disease of the left facial and fronto-temporal bones and osteolytic change left mandible. This patient complained of severe spontaneous bleeding of left mandibular premolar area and it was suspected as central hemangioma of the left mandible and craniofacial FD. Angiogram disclosed generalized dilation of the external carotid artery and its branches, especially terminal branches of the left facial and inferior alveolar arteries. But no specific abnormalities, such as A-V shunt, venous lake, or early venous drainage, was seen. So it was diagnosed craniofacial FD with hypercellularity and generalized bony recontouring was performed via coronal and transoral approaches.

편측 왜소증의 얼굴을 상하악과 하악 모두 신장할 필요가 있는 경우 하악을 신장하여 상악도 신장시키는 방법을 최근 소개한 바 있으나 본 논문에서는 오히려 상악을 신장시킬 때 하악도 같이 신장시키는 방법을 개발하여 좋은 결과를 얻었다. 두 명의 편측안면 왜소증 환자에서 양악 동시에 골 신장술을 시행하였다. Ortiz Monasterio의 방법과 달리 상악은 구내 르포트씨 제일 골절단술을 시행하였고, 하악은 구내 시상분할 골 절단술을 이용하여 골신장시 저항을 최소한으로 줄이려 하였다. 편방향 구내 골 신장기와 스플린트를 이용하여 양악 골신장술을 시행하였다. 5일의 잠재기 후 매일 1mm의 골신장을 시행하였고 6주에서 8주간의 경화기를 둔 후, 골 신장기와 스플린트를 제거하였다. 골신장 길이는 각각 13mm와 15mm이었고, 특이할 만한 부작용은 관찰되지 않았다. 이에 본 교실에서는 상악신장을 바탕으로 양악을 신장시키는 새로운 술식을 보고하는 바이다.

지면의 한계 상 다양한 악성종양을 모두 다룰 수가 없어, 주로 상악에 발생하여 골 파괴를 야기하고 있는 증례들의 영상 소견을 소개하고자 한다. 악성종양의 진단 과정에는 보통 CT, MRI, PET/CT 등의 특수 장치들이 필요하지만, 개원의들이 일반 환자들의 진단과 치료 과정에서 흔히 접하게 되는 파노라마 방사선사진을 중심으로 하여, 악성종양들의 병인이나 기본적인 악성종양에 대한 설명 보다는 실제 임상 증례들을 통해 악성종양의 공통된 영상 소견 특징을 찾아보고자 한다.

This is to report a case of secondary reconstruction after partial mandibulectomy by using of marrow-cancellous bone and cortical bone harvested from the iliac crest in the case of an ameloblastoma on the mandible. According to the past experimental studies, the marrow and cancellous bone have the marked osteogenic potential of hematopoietic. And the cortical bone has the highest activity of bone induction, which is mediated through the action of bone morphogenic protein(BMP). This grafting technique, the combination of PMCB and cortical bone, has advantage in restoring lange defect of the mandible.

Distraction osteogenesis is a well-estabilished procedure of membraneous bone formation and has been used to correct craniofacial deformities in dentofacial orthopedic-surgery area for decades. In this articale, distraction osteogenesis is used for treatment of facial asymmetry. The patient underwent procedures to lengthen the mandibular ramus and body. After distraction, orthodontic treatment was done for ooclusal settling.

Purpose: Inevitably, Maxillary structural defect follows maxillary cancer extirpation. Maxillary reconstruction is over every surgeon's head. Every physician tried to overcome limited donor site of craniofacial defect. We considered to suggest optimal method of inferior orbital wall defect in functional point as well as esthetic point. Methods: We performed wide excision of maxilla and vascularized partial thickness calvarial bone flap to reconstruct the defect from cancer extirpation in three cases. We select ipsilateral superficial temporal artery, vein and outer cortex of parietal bone flap as donor. And we applied bone flap as inferior orbital wall structure. The bony surface was wrapped with fascia to prevent direct contact between orbital contents and rough bony flap surface. Computed tomography image was checked during follolw up period. Results: We can observe these patients for over two years. In all three cases, We can get fair inferior orbital wall structure. Even though they got radiation therapy, there was no limitation of extraocular movements, no diplopia. no enophthalmos. Also there was minimal donor site morbidity. Conclusion: We suggest vascularized calvarial bone flap is practically excellent strategy for inferior orbital wall reconstruction.

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.
