DIAGNOSTIC VALIDITY OF BONE SPECT IN ORAL MAXILLOFACIAL REGION

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.

Noninvasive Functional therapy of Mandibular Condylar Fracture / 영남의대학술지

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.

The Distribution and Trend of Malocclusion Patients Visited at Department of Dentistry in Orthodontics / 영남의대학술지

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.
