Abstract PDF: Mandibular retrusion showing the facial problem with a marked maxillarry incisors protrusion and chin deficiency, resulting in a highly convex profile is uncommon in Korea.. The large incisor overjet and deep-bite create functional limitations and unpleasing esthetic result. The majority of theses cases are susceptible to correction by orthodontic therapeutic methods. But severe Class II retrognathic cases in which orthodontic treatment alone has not been capable of achieving good results. Orthognathic surgery offers several approaches. In this case, mandibular advancement by bilateral sagittal split ramus osteotomy and augmentation genioplasty has a special surgical problems. The suprahyoid muscle gorup are lengthened if the body of the mandible is surgically repositioned anteriorly. Instability of results and relapse return to original position shoud predicted during post-surgical muscular readjustment.. To maintain maximum correction with this technique, it is suggested that the mandibular body be well rotated forward at time of surgical intervention and overcorrected anteriory as much as possible. So, the authors report the case with review of concerned literature.

Diagnostic Reliability & Case Reports Of The Dynamic MRI For Temporomandibular Joint Disease: Jin Ho Park, Byung Rho Chin, Woo Mok Byun; Yeungnam Univ J Med. 1995;12(1):141-148. Published online June 30, 1995; DOI: https://doi.org/10.12701/yujm.1995.12.1.141

Abstract PDF: The Magnetic resonance imaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very effective to evaluate the disk position under function. This is to study the correlation between the clinical diagnosis and the findings of dynamic MRI for diagnosis of internal derangement of the 7 patients were examined clinically, and the movement of TMJ meniscus was reviewed in the dynamic MRI. MRI was very reliable to diagnose the amount of anterior displacement of articular disc, the structural abnormality of temporomandibular joint, the cause of functional limitation, and to differentiate the muscle related pain & dysfunction

Noninvasive Functional therapy of Mandibular Condylar Fracture.: Jin Ho Park, Jong Sup Kim, Nan Hi Im, Hong Sik Yun, Byung Rho Chin, Hee Kyung Lee; Yeungnam Univ J Med. 1994;11(2):398-404. Published online December 31, 1994; DOI: https://doi.org/10.12701/yujm.1994.11.2.398

Abstract PDF: Functional recovery after mandibular condyle fracture was a contradictory result of many authors. The treatment goal of condyle fracture has been directed primarily toward restoration of functional movement of the mandible. We selected some patients who requested functional therapy in many cases of condylar fracture, depend on pattern of fracture, patient's demand, occlusion, age. Without intermaxillary fixation, we induced the patients to rapid healing of temporomandibular function and normal mandibular protrusive, lateral movement as a result of early functional therapy by activator. So, the authors report the cases with review of concerned literature.

Abstract PDF

1.050 patients who visited orthodontic dental department from 1983 to 1994, were surveyed on the yearly tendency of orthodontic patient distribution and state by means of Angle's classification. The results were as follows : 1. There was increased visiting rate of patient per year and higher visiting rate in female than in male. 2. 8-15 age group was 61.4% in total visiting patients and over 20 age group was 18.5%, under 7 age group was 8.1%. 3. Class I malocclusion was 42.2%, class II div 1 was 22.5%, class II-2 was 3.9%, class III was 29.1% and cleft lip & palate was 2.0% in total visiting patient. 4. As showed the living distribution, Namgu and Susunggu's patients were 43.7% of the total patients. 5. There was increased tendency for the number of the patient to be received orthognathic surgery.

Abstract PDF: This is a case report and review of literature that deals with hemifacial microsomia corrected by costochondral graft, Lefort I osteotomy and bilateral intraoral sagittal split ramus osteotomy. Patient, 23 years old female, had visited to treat the esthetic problem due to a deviation of jaw. On the basis of clinical and radiographic examinations, she was diagnosed as hemifacial microsomia. First, costochondral graft was performed to bridge the defect between glenoid fossa and body of mandible. After 11 months,. Patient was performed a Lefort I osteotomy and bilateral intraoral sagittal split ramus osteotomy to create a symmetric jaw. Patient was satiesfied with final esthetics and there have been no evidence of infection ill now.

The comparison of influence of difficulties in nasal breathing on dentition between different facial types.: Myeong Jin Lee, Chang Kon Lee, Sup Jong Kim, Jin Ho Park, Byung Rho Chin, Hee Kyung Lee; Yeungnam Univ J Med. 1993;10(1):37-47.

Abstract PDF: It is. commonly assumed that nasorespiratory function can exert a dramatic effect upon the development of the dentofacial complex. Specially, it has been stated that chronic nasal obstruction leads to mouth breathing, which causes altered tongue and mandibular positions. If this occurs during a period of active growth, :the .outcome is development of the "adenoid facies". Such patients characteristically: manifest a vertically long lower third facial height, narrow alar bases, lip incompetence, a long and narrow maxillary arch and a greater than normal mandibular plane angle. But several authors have reported that so-called adenoid facies is not always associated with adenoids and mouth breathing, and that a particular type of dentition is not alwarys found in mouth breathers with or without adenoids. Some authors have believed adenoids lead to mouth breathing in cases with particular facial characteristics and types of dentition. We assumed that the ability to adapt to individual's neuromuscular complex is various. So, we compared the difference of influence of mouth breathing between childrens who have different facial types. This study included 60 patients and they were divided into three groups by Rickett's facial type. Their dentition and tongue position were compared. The results are as follows. 1. There is a significant difference in arch width of upper molars between different facial types. Especially dolichofacial type patients have narrowest arch width. 2. There is a significant difference in tongue position between different facial types. Especially dolichofacial type patients have lowest positioned tongue.

Abstract PDF: A clinical review of 34 cases of aortic dissection which were admitted to Yeungnam University hospital between March 1983 and April 1992. The results are as follows: 1. The peak incidence was in 5th, 6th decade and male to female ratio was 1.83:1. 2. The most common cause of aortic dissection was atherosclerosis and hypertension (79%). 3. The most common presenting symptom was pain (73%). but dyspnea, palpable mass, murmur, shock were also observed. 4. Abnormal electrocardiographic finding was myocardial ischemia in 6 cases, arrhythmia in 5 cases, LVH in 5 cases. 5. The X-ray findings showed abnormal aortic contour in 10 cases but normal X-ray finding was observed in 63% of DeBaKey Type III. 6. The most common diagnostic procedure was echocardiogram and abdominal Ultrasonography. 7. The mortality of all cases was 20%, operation mortality was 18% but no death of medically treatment in medical indication.
