The minor fissure is an important anatomical landmark in the localization of the pulmonary diseases. For the evaluation of the normal feature of the minor fissure, we analyzed the high-resolution computed tomography (CT) scans in 51 normal patients. The purposes of this study are to evaluate the normal appearance of the minor fissure on high-resolution CT scans and to compare it with that on the coventional CT and chest radiographs. We analysed the morphologic feature of the minor fissure on the high-resolution CT scans in 51 normal patients, and compared it with that on the conventional CT scans. On the high-resolution CT scans, we particularly paid attention to the completeness and types according to Berkmen classification. And finally, we compared the types determined by the high-resolution CT scans with those by the plain radiographs. In most patients (n=47), the minor fissure was seen as a hyperattenuating line or hand on the high-resolution CT scans. In contrast, it was mostly seen as a lucent zone on the conventional CT scans (n=44). Of 47 patients having a hyperattenuating line or band on the high resolution CT scans, the minor fissure was considered to be complete in 17 patients (36%), and incomplete in 30 patients (64%), who had defect at medial portion of the minor fissure. The most common type of the minor fissure seen on the high-resolution CT scans was type I variety (n=23), followed by type IIa (n=10) and type II (n=8). We could not determine the type in six patients. The type determined by the high resolution CT scans was highly well correlated with that determined by the plain radiographs (p<0.05). In conclusion, the minor fissure was seen on CT studies as variable appearances and high-resolution CT scans were superior to the conventional CT scans in the evaluation of the minor fissure. The type of the minor fissure determined by the high-resolution CT scans were well correlated with those seen on the radiographs.

TMJ internal derangement has been treated by the conservative methods and the surgical methods according to the clinical state. There are several surgical methods for treatment of TMJ internal derangement, such as disk repositioning and repair, diskectomy with and without grafts, articular surface contouring, high condylectomy, condylotomy, and arthroscopic surgery etc. Especially, it has been reported that the condylotomy produced the increase of the joint space, the pain relief, the elimination of the joint dysfunction due to the antero-inferiorly movement of the condyle, and the condylar morphologic change resulted from the progressive remodeling in TMJ without the surgical intervention within the TMJ. We have performed EVRO(extraoral vertical ramus osteotomy) to the 5 patients diagnosed as ADDWR(Anterior disk displacement with reduction) from June 1997 to December 1997 in the Chin-Hae military hospital. We diagnosed them with MRI and clinical examination. And we compared the preoperative symptoms with postoperative 2 months symptoms. They were compared by Helkimo index, mandibular mobility index, and pain scale. Anamnestic Index(Ai) was changed from 2.0 preoperatively to 1.2 postoperatively, clinical dysfunction score from 11.8 to 2.8, and Clinical Dysfunction Index(Di) from 2.8 to 1.2. The pain scale of the affected side was changed from 4.4 to 2.6 and that of the non-affeted side from 2.2 to 2.6. The maximal mouth opening was changed from 35.2mm to 40.9mm, right lateral excursion from 7.8mm to 8.0mm, left from 8.8mm to 7.0mm, and protrusion from 6.2mm to 6.2mm. In these results, we could not expect any excellent improvement of the clinical symptoms during the immediate postoperative periods. But we could observe the disappearance of the joint noise and the improvement of the clinical dysfunction score. On the basis of the results of the previous investigations about condylotomy effect which presented the condyle position were changed antero-inferiorly in the articular fossa during the immediate postoperative period, the displaced condyles may prevent wide mouth opening. Therefore it is elucidated that the improvement of the maximal mouth opening and other functions were restricted during the immediate postoperative periods. After long term follow-up period, the symptomatic and functional improvement will be expected by the passive repositioning of the proximal segment. We report the preliminary results with the related references.

STUDY DESIGN: Two case reports. OBJECTIVES: We present two cases of quadriplegia after posterior decompression with fusion caused by a suspicious reperfusion injury of spinal cord without remarkable surgical insult. SUMMARY OF LITERATURE REVIEW: Posterior decompression and posterolateral fusion have been reported as effective procedures in patients with multilevel myelopathy. However, postoperative spinal cord injury without remarkable intraoperative technical damage has been reported in a few articles. Reperfusion mechanism was suggested as one of the leading causes and reported in some animal models. MATERIALS AND METHODS: There was one case of ossification of the posterior longitudinal ligament and one developmental multilevel stenosis that underwent laminectomy with lateral mass instrumentation. After surgery, the patients presented with quadriplegia; MRI demonstrated swelling of the spinal cord and intramedullary lesion in two cases. RESULTS: After surgery, the patients presented with quadriplegia; MRI demonstrated swelling of the spinal cord and intramedullary lesion in two cases. CONCLUSION: Although patients with such a medical condition are rare, it is difficult to predict postoperative swelling of the spinal cord before surgery. The surgeon should thus be aware of such rare disease conditions involving the spinal cord before the surgical procedure.

OBJECTIVES: There have been no consistent reliable and valid tool for examining the psychosocial problems for the patients with mental disorders in Korea. The purpose of the present study is to develop a scale that examine the psychosocial problems for the patients with mental disorders and to test its reliability and validity. METHODS: To identify the psychosocial problems for 1,100 patients with mental disorders were selected in university hospitals and professional training institutes. And the items of the psychosocial problems were taken from them and divided them into individual and environmental categories. The representative items were established among these items of psychosocial problems and a questionnaire for a pilot study was made based on the representative items. The pilot study was done for 306 patients with mental disorders using the questionnaire to investigate reliability of the questionnaire. After the pilot study items and format of the questionnaire were revised and complemented. The revised questionnaire was given to 600 patients with mental disorders to test its validity and reliability and new scale for psychosocial problems was developed. RESULTS: At the pilot study, which was performed with 1,100 patients, 3,200 items of psychosocial problems of 205 types were selected. Among these items 78 representative psychosocial problems items were withdrawn. Fifty-eight psychosocial problem items were finally set for the questionnaire after discussing them with the expert groups and examining its content reliability. Forty-seven psychosocial problems items were finally selected and given to 306 subjects at the pilot study. At the main study in which 600 subjects were tested inner-reliability. Correlation between items and scale was relevant and correlation coefficient between test and retest was high. The finally developed psychosocial problems testing scales were consisted of 46 testing items into 9 areas. CONCLUSION: The Psychosocial Problems Assessment Scale, which were developed at this study is proved to be valid and reliable and it will be able to be used to examine overall psychosocial problems for the patients with mental disorders in Korea.
