  • 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%).

  • 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.

  • 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.

  • Objectives : This research aimed to develop a new etiologic classification for traditional Korean Medicine in order to respond to the social and environmental change. Methods : We reviewed the existing theories on etiological classification for East Asian Medicine thoroughly and discussed the problems and limitations. Based on the experts' consensus, we abstracted disease factors and etiologic items. Results : The disease factors are classified into three parts: the human body, the environment, and the interaction between the human body and the environment. We defined them as the inner factor, the external factor, and the interaction between the inner and the external factors. The inner factor is free from the influence of the environment, and it causes diseases solely from the components of the human body. It is divided into genetic factors. The external factor is defined as a case when a disease occurs due to a factor outside the human body and includes external injuries, environmental pollution, and natural disasters. The interaction between the inner and the external factors is a disease factor that causes diseases by the interaction of the human body and the environment and includes emotions, habits, and social environment. As a result of the analysis, it was possible to see the meanings at a single glance as the scattered and fractional meanings were integrated with focus on medicinal herbs, but the increasing number of analyzed medicinal herbs tended to more and more complicate their relationships, thus, requiring additional work like filtering. Conclusions : The new etiologic classification of Korean Medicine fully reflects the perspectives on life in Korean Medicine while embracing the changes in modem society. Also, by avoiding the usage of ambivalent terms and wrong classification methods, the new classification system constructs intuitive and concise etiology and improves usability in clinical medicine.

  • A total of 636 patients of primary infertility were analyzed by computer on the basis of statistical evaluation of etiological factors and therapy with the outcome of the pregnancy. In this report, it included the results of the study analyzed the single etioligic factors responsible for the primary infertility with the outcome of the pregnancy. 1. Two hundred and fourty one patients out of a total 636(37.9%) achieved pregnancy. 2. Four hundred and fifty nine patients out of a total 636(72%) had a single etuiologic factor responsible for the primary infertility. 3. One hundred and seventy six patients out of 459 parients (38.3%) who had a single etiologic factor responsible for the primary infertility achieved a pregnancy. 4. The endometriosis was the most frequent responsible factor for the primary infertility. 5. The success rate of the pregnancy was different in each etioligic factor responsible for the primary infertility. The highest success rate of the pregnancy was in the patients who had the intermediate factor responsible for the primary infertility as much as 66.7% of the patients. 6. The expectancy of the pregnancy in terms of the duration of the therapy and the follow-up was variable and depended upon the etiologic factor of the primary infertility.

  • 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.

  • Gastroesophageal reflux is thought to be an important etiology of the various upper aerodigestive tract disease. To investigate the role of gastric acid and pepsin as an etiologic factor of laryngotracheal stenosis, and the difference of injury by synthetic gastric juice between in ciliated respiratory epithelium and in squamous epithelium, experimental study was carried out using rabbits. Mucociliary transport affected by synthetic gastric juice was also studied in dogs. Synthetic gastric juice of low pH caused serious damage and Impairment of mucociliary transport in the epithelium of the larynx and trachea. Gastric acid played major role in the mucosal damage. Squamous epithelium of vocal folds and pharynx was more resistant to synthetic gastric juice than respiratory epitheium. In conclusion, gastroesophageal reflux may be an etiologic factor in the developement of laryngotracheal stenosis, so the adequate management is necessory In patients of laryngotracheal stenosis.
