  • Recently the goal of orthognathic surgery has been focused on esthetic improvement of the patients. Also early corrective surgery was favorable selected by most of the oral and maxillofacial surgeons. We should consider the etiologic factor of the patient's dentofacial deformities when treatment is planned, because this is the major factor in estimating the predictability or stability of result. The more researches were carried on the etiologic factors of the dentofacical deformities, The more possibility of the early surgical correction will be increased. The authors analyzed about etiologic factors and epidemiologic studies of the forth patients who had received the orthognathic surgery. The analyzed results were as follows: 1. The predilection ration between male and female was 17:23, and 32 patients (80%) of 40 patients were aged twenties. 2. 26patients(65%) complained estetic problems as well as functional problems. 10 patients(25%) complained only esthetic problems, and 4 of 40 patients complained only functional problems. 3. Mandibular prognathism was found to be done most frequently(25, 39%). Facial asymmetry (13, 20%) and angle hypertrophy were found to be next in sequence. 4. Sagittal split ramus ostetomy was done most frequently(27, 35%). Lefort I osteotomy(13, 17%), angle reduction (12,16%), and genioplasty(11, 15%) were done also. 5. The number of the cases due to nonspecific etiologic factor was 22(55%), that of cases due to inhertied tendency was 12(30%), that of cases due to congenital anomaly was 3(7.5%), and that of cases due to trauma was 3(7.5%). 6. The number of patients who got only maxilliary surgery was 2(5%), that of patients who got only mandibular surgery was 23(57.5%), and that of patients who got simultaneous two jaw surgery was 15(37.5%).

  • Background: Carcinoma of the tongue is the most common intra-oral malignancy in Western countries. Incidence and mortality rates have increased in recent years, and survival has not improved. This study aimed to determine etiologic factors for tongue cancer with age-sex matched case-control data. Materials and Methods: 47 patients with carcinoma of the tongue referred to our oral medicine clinic between years 2005-2006 were analyzed and compared with control group data. The medical records, including family history of cancer, dental trauma, and history of abuse of alcohol and tobacco products was recorded for all subjects. Chi square comparison tests and linear regression analysis were performed using the SPSS program for statistics. Results: Patient and randomly selected control groups each consisted of 30 male and 17 female subjects with mean ages 53.2 (${\pm}12.6$) and 52.6 (${\pm}11.5$) years respectively. Smoking and alcohol abuse proportions were significantly higher in the patient group (p=0.0001, p<0.0001 respectively). Chronic mechanical trauma was observed in 44.7% of the patients and 17.0% of the control group (p=0.004). Similarly, family history of cancer of any type (for the first degree relatives) was found to be more common in the patient group (p=0.009). On regression analysis, alcohol abuse, family history of cancer, smoking, chronic mechanical traumas appeared as significant etiologic factors (p=0.0001). Conclusions: We believe that field cancerization may become evident in oral and oropharyngeal mucosa with multiple steps of molecular changes starting from the first sign of dysplasia with chronic exposure to etiological factors. Chronic trauma cases need particular attention to search for very early signs of cancer.

  • The main current in the pathology of oriental medicine is composed of etiologic factor, pathogenesis and clinical manifestation. The access of a disease is consist of etiologic factor, location of the lesion, nature of the disease and patient's condition. The nature of disease and the property of a drug are inseparably related to each other. The nature of disease is composed of six exogenous factors, cold and heat, deficiendy and excess, Yinyang and pain. Cold nature is divided into cold symptom due to excess and asthenia cold, fever nature is divided into sthenic fever and asthenic fever. According to the location, cold and heat can be subdivided into heat in the upper and cold in the lower, cold in the upper and heat in the lower, exterior cold and interior heat, exterior heat and interior cold. Yin syndrome characterized by hypofunction of the viscera is generated from insufficiency of yang-qi, excess of yin-coldness, deficiency of both qi and the blood.

  • Objective : Trauma has been a controversial issue although it has been considered to be a major factor for the temporomandibular disorder(TMD). We evaluated the relationship between macrotrauma or microtrauma and TMD. Methods : This study was performed in patients with TMD undergoing treatment at SNUBH from October 2006 to January 2007. Sixty one male patients and 166 female patients(total 227) were included and the average age was 34 years(ranging from 14 to 85 years). We investigated the possible etiologic factors, diagnosis and treatment with the review of medical records and radiography. Chronic pain, depression, somatic score(including pain item), somatic score(excluding pain item) were evaluated on the basis of diagnostic index from the Research Diagnostic Criteria on TMD. Results : Eighteen patients(7.9%) out of 227 patients suffered from TMD as a result of macrotrauma. Ninety four(41.4%) patients had microtrauma and six patients(2.6%) had both macro- and microtrauma(etiologic factor). The main symptoms included pain. joint noise and mouth opening limitation while the other symptoms were headache and tinnitus. The patients had suffered from TMD for average 41 weeks (ranging from 1 to 480 weeks). 116 patients took splint as a major treatment. As a prognosis, 19 patients(8.4%) recovered completely. 26(11.0%) had improvement and 181(80%) had persistent symptoms. 1 patient(0.4%) underwent an arthroplasty. Diagnostic index from RDC chart showed that macrotrauma was the highest score(except depression score) among the other etiologic factors. Conclusion : This study showed that macro- and microtrauma can be considered to be the major etiologic factors of TMD, which also affect the chronic, depression and somatic discomfort.

  • The cause and mechanism of eye diseases are follow in biblography. The etiological factor of eye diseases are nearly caused by heat. It is important to distinguish deficiency and substance. In external etiologic factors wind-fever is most of all in six exogenous factors. In internal etiologic factors xu(deficiency) of kidney, blood and fire of seven emotions are lots. In factors other than the internal and external, eating greasy food and hyper-caloric food are a lot of case. In relation with the yin-yang andxu-shi, ther are a lot of eye diseases symptom as dark-dizziness due to the yin-xu of hepatic-kidney. According to eight principles of differentiation of syndromes, syndromes of exterior, heat, shi, almost fall into the category of yang and syndromes of interior, cold, xu, nearly fall into the category of yin. In interior treatment, inducing wind and clearing heat, using Qi and tonifying blood, tonifying and suing of hepatic-kid ney are useful and often used treatment.

  • In spite of the development of scientific and medical technology, the rate of prevalence and death of the chronic disease gets higher. Therefore people come to know prevention is more important than treatment in disease. In Western, it is nearly after 1970's when it is revealed that the major factor of chronic disease comes from habitual behaviors in everyday life. But that is common idea in Oriental Medicine since thousand years. In Oriental Medicine, the main cause of disease is composed of natural factor including climate condition, living-life factor, psycho-social factor, constitutional factor, inbody-pathologic-substance factor, and other factors including habits of using drug and medical service, injury, environmental pollutions, and occupational etiologic factors. Among these, the major factors of disease in modern society are lifestyle factors like the tendency of choosing and intaking food, the level of physical activity and labor, smoking and drinking alcohol, psychological tendency, the habits of using drug and medical service and so on. This is a practical aspect of oriental medicine where the most important etiologic factor comes from human behaviors, not from external factors like germ or virus. So that etiology in Oriental Medicine where improvement in the way of life is needed to prevent disease would play an important role in modern society.

  • Objective : We analyzed 3 clinical cases to estimate the possibility of shanghanlun as a completed clinical text which has its own diagnostic system. Methods : We collected 3 cases treated by huang lian e jiao tang conducted by a practiced shanghanlun doctor and defined the conceptional meaning of each provisions by analyzing the application of them in each case. Results : Shanghanlun provisions dualized with Je Gang(提綱) and Jo Mun(條文) is the record of preceding factors which describe the phenomenon initiating the diseases. Conclusions : Rudimentarily a factor can bring about many outcomes, so if shanghanlun is structured record of the factors which can make a human sick from many diseases, it can be used as the completed clinical text only with those 113 prescriptions. Factors that shanghanlun recorded seem somewhat different from western conventional medicine because the field of each factors are very varied from biological phenomenon to psychological phenomenon. However it is not that weird because psychosomatic medicine in western conventional medicine also point out the factors come from mental, society and behavior.

  • Chronic recurrent TMJ dislocation results in difficulty of mastication, speaking, and swallowing due to the limitation of the mandibular movement. Etiologic factors are considered as the looseness of the capsule and ligaments, the decrease of the articular eminence, condylar morphologic change, muscular disharmony near by TMJ, and the decrease of the vertical length of the mandibular ramus. Treatment approach has been suggested that surgical methods are selected for the correction of the etiologic factors when conservative treatments are not effective. Many surgical methods have been reported such as eminectomy, eminence augmentation, condylotomy, and zygomatic arch down fracture technique. We performed the eminence augmentation through interpositional bone graft in chronic recurrent TMJ dislocation. This method leads to favorable postoperative result without recurrence and complication, so we report the case with related references.
