174 patients who visited in the Department of Dentistry, College of Medicine, Yeungnam University from 1983. 7. 15 to 1986. 11. 30 were surveyed on the tendency of patient distribution and the state of Angle's classification. The results were as follows 1. There was increased visiting rate of patient per year. Female outnumbered male by a ratio of 1.3:1. 2. 8-15 age group was 74% in total visiting in the most frequency. The average visiting numbers of each month were higher among the vacation and was about 74% in that period. 3. As showed the living distribution, Nam Go and Su Sung Gu's patients were 53% of the total. 4. As the motive of visiting in Dental Department, patient of 30% in total patients visited for themself to receive orthodontic treatment and other was introduced patients. 5. By classification, Class I malocclusion was 63% in total visiting patient, Class II malocclusion 17%, Class III malocclusion 20%. Crowding among Class I malocclusion was 60%.

The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue change after mandibular setback surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patient (12 male and 13 female) who had severe anteropostrior skeletal discepancy. These patient had received presurgical orthodontic treatment and surgical treatment which is bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The result were as follows: 1. After mandibular bilateral sagittal split ramus osteotomy, lower facial soft tissue horizontal posterior changes were high significance value. but vertical soft tissue changes were low significance value. 2. After mandibular bilateral sagittal split ramus osteotomy, relative upper lip protrusion increased(p<0.01) and relative lower lip protrusion decreased(p<0.01) and lower facial soft tissue thickness increased(p<0.01).

Oro-facial dyskinesia (OFD) is involuntary, abnormal, uncontrolled and stereotyped movements,
consisting of forehead furrowing, eye opening and closing, smacking and pursing of the lips, lateral
deviation and protrusion of the tongue, and occasionally lateral deviation and protrusion of the jaw.1
OFD is known to have various complications including speech difficulty, chewing and eating disorders,
and social embarrassment; facial muscle stiffness, mucosal and gingival traumatic lesions. In addition,
it may leads to cranio-mandibular joint (TMJ) complications in the presence of intense and prolonged
abnormal movements, with pain and degeneration.1,2 There is no previous report of TMJ dislocation
due to OFD. In this report, we describe a patient who developed bilateral anterior TMJ dislocation
due to OFD which occurred following intra-cranial hemorrhage (ICH).

Enlargement of the gingival caused by phenytoin. An anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions. 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingival to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.

The mechanisms involved in brain neuronal damage in ischemia are related to the elevation of cytosolic calcium concentration and calcium antagonist is considered as a promising drug that may alleviate ischemic neuronal damage. Using transient global ischemia model of Mongolian gerbil, we studied the effect of nimodipine, a cerebroselective calcium antagonist, on ischemic brain edema. We treated each gerbil intraperitoneally with nimodipine (lmg/kg) or the same amount of saline 30 minutes prior to ischemia, and transient global ischemia was induced by means of clipping both common carotid arteries either for 10 minutes or for 45 minutes. Three hours after reperfusion, the animals were decapitated and the water content of the bain was determined by oven dry method. With 10 minute ischemia the brain water content in nimodipine pretreatment group (78.6 +/- 0.2%) was lower than that in saline pretreatment group (79.1 +/- 0.4%) significantly (p<0.05). But with 45 minute ischemia nimodipine pretreatment did not reduce the postischemic increase of water content compared with saline pretreatment (79.8 +/- 0.4% and 79 6 +/- 0.4%, respectively; not significant). Our results suggest that nimodipine pretreatment may suppress the development of ischemic brain edema and its effect depends largely on the extent of brain ischemia.

Single photon emission computed tomographic(SPECT) imaging, performed at oral and maxillofacial surgery department, is valuable in assessing temporomandibular dysfunction, looking for metastases in patients with malignancies, diagnosing facial asymmetry. Conventional planar scintigraphy is limited by two-dimensional representation of three-dimensional structures. The SPECT exam, by sectioning through a distribution of tracer, eliminates the obscuring effects of tracer located outside the plane of interest. In our department, we used this image for four type cases retrospectively. 1. Those patients who have facial asymmetry 2. To find metastases in patients with malignacies 3. In combination with magnetic resonance imagine, to confirm the diagnosis of internal joint derangement 4. To evaluate the viability of grafted bone. Recently, this image is able to be used in those patients whose symptoms etiology cannot be explained by other diagnostic techniques.

Congenital esophageal stenosis due to tracheobronchial remnants is one of main forms of congenital esophageal stenosis, and it was first described by Frey and Duschel in l936. An 18-month-old male presented with underdevelopment and dehydration state due to persistent vomiting several times per day since 3 months after his birth. Esophagogram revealed an elongated and diiated esophagus with marked stenosis at distal portion. Partial distal esophagectomy was performed. Histologically, the thickened esophageal wall is composed of tracheobronchial remnants including hyaline cartilages, mucous glands, and ductal structures lined by ciliated respiratory epithelium under stratified squamous mucosa.
