Seventy-two cases of benign fibro-osseous lesions of the jaws were reassessed, and a modified classification is proposed that may be helpful in their understanding and management. The anatomical distribution of these cases is described and compared to previously reported cases. The histogenesis of each particular lesion is also discussed. Correlative analysis of histopathologic and oral radiographic features is essential for definitive diagnosis.

OBJECTIVE: To investigate the expression of E-cadherin in benign, borderline, and malignant ovarian tumors. METHODS: An immunohistochemical technique was applied to formalin-fixed paraffin-embedded samples of 20 benign cystic ovarian tumors, 14 borderline ovarian tumors and 13 ovarian carcinomas. Expressions of E-cadherin immunostaining in three histological types were compared, and the survival rate in malignant ovarian cancer according to E-cadherin expression was also assessed. RESULTS: E-cadherin was positively or heterogeneously expressed in both benign and borderline ovarian tumors. But it was negatively, heterogeneously, or positively expressed in malignant ovarian tumors. The difference of expression of E-cadherin between borderline and malignant ovarian tumors was statisticaIly significant (p<0.05). In ovarian carcinoma, there was difference between negative and positive group in survival (p<0.05). CONCLUSION: Our results suggest that alterations in E-cadherin seem to occur at a later stage of the ovarian carcinogenesis, and may have some prognostic value in malignant ovarian tumor.

PURPOSE: The goal of this study was to develop a technique for creating a computerized composite maxillofacial-dental model, based on point-based surface best fit algorithm and to test its accuracy. The computerized composite maxillofacial-dental model was made by the three dimensional combination of a 3-dimensional (3D) computed tomography (CT) bone model with digital dental model. MATERIALS AND METHODS: This integration procedure mainly consists of following steps : 1) a reconstruction of a virtual skull and digital dental model from CT and laser scanned dental model ; 2) an incorporation of dental model into virtual maxillofacial-dental model by point-based surface best fit algorithm; 3) an assessment of the accuracy of incorporation. To test this system, CTs and dental models from 3 volunteers with cranio-maxillofacial deformities were obtained. And the registration accuracy was determined by the root mean squared distance between the corresponding reference points in a set of 2 images. RESULTS AND CONCLUSIONS: Fusion error for the maxillofacial 3D CT model with the digital dental model ranged between 0.1 and 0.3 mm with mean of 0.2 mm. The range of errors were similar to those reported elsewhere with the fiducial markers. So this study confirmed the feasibility and accuracy of combining digital dental model and 3D CT maxillofacial model. And this technique seemed to be easier for us that its clinical applicability can good in the field of digital cranio-maxillofacial surgery.

BACKGROUND: Postoperative patients frequently associate postoperative backache with epidural anesthesia administered for the operation. Epidural steroids are often used for the treatment of low back pain. We performed this study to compare the effect of epidural triamcinolone on the incidence and severity of postepidural backache after cesarean section. METHODS: Eighty patients scheduled for cesarean section under epidural anesthesia using 2% lidocaine received 40 mg of triamcinolone (n=40) or 1ml of normal saline (n=40) epidurally via indwelling catheter after delivery. Backache were checked preoperatively and 24, 48, 72hr postoperatively using VAS score. A patient was considered to have postepidural backache when the postoperative VAS score was higher than the preoperative score. RESULTS: The incidence and severity of postepidural backache were much less in triamcinolone group than in control group (p<0.05). CONCLUSION: Epidural triamcinolone has a preventive effect on postepidural backache in cesarean section patients.

PURPOSE: Due to the biological characteristics of cardia cancer, prognosis is poor. It is therefore essential to achieve a sufficient proximal resection margin to maximize survival. The authors studied gastric cardia cancer, focusing on adenocarcinoma. METHODS: One-hundred fifty patients who were diagnosed with gastric cardia cancer and underwent surgery between January 1990 and December 2006 by a single surgeon were included in this study. RESULTS: Of the 150 cases, 141 were adenocarcinomas, 4 were carcinomas, and 3 were leiomyosarcomas. In the adenocarcinoma group, the male-to-female ratio was 2.62:1. There were 2, 60, and 79 (56.0%) cases of adenocarcinoma type I, II, and III, respectively, and there were 32 (22.7%), 18 (12.8%), 70 (49.6%), and 21 (14.9%) cases of stage I, II, III, and IV tumors, respectively. The mean distance from the proximal tumor to the resection margin was 1.93+/-2 cm pathologically, and there was tumor invasion of the resection margin in 4 cases (2.8%). In the 10 cases of extended surgery in type II, the mean distance was 5.85+/-3.67 cm, with no tumor invasion of the resection margin. Recurrence occurred in 30 (21.3%) cases, and 5 of those cases were local anastomotic site recurrences. Cumulative survival was 81.3%, 77.8%, 51.4%, and 28.6% for stage I, II, III, and IV tumors, respectively. CONCLUSION: Although it is possible to remove the tumor with an appropriate resection margin by only an abdominal incision, the surgeon should always keep in mind the possibility of a thoracoabdominal incision when operating on a patient with esophageal infiltration.

This study analyzed the incidence of wound infection after the operation of mandibular third molar extraction in relation with antibiotic prophylaxis with the object of young and healthy patients. The study object was 1,177 mandibular third molars of 850 men of 20 to 25 years old without any specific systemic disease. Three methods of preventive antibiotic medication were selected according to the preventive antibiotic medication previously reported; three experimental groups were selected based on them, and the antibiotic used was amoxicillin((R)Kymoxin, Yuhanyanghaeng, Seoul). The group 1 includes the patients that took the antibiotic orally before the operation(one hour earlier, 500mg) and for three days after the operation(250mg per time, three times/day), the group 2 is the ones that took the same antibiotic orally only once about one hour before the operation(500mg), and the group 3 did not take any antibiotics before and after the operation. And to compare the difficulties and the degrees of extraction during operations which can be possibly related to the wound infection after the operations, the mandibular third molars' impacted depths and extraction methods were investigated as well. To check if the wound was infected, observations with an internal of one week were performed twice after the operation, and the meaningfulness of the infection incidence was verified through Chi-square test using SPSS program(SPSS Inc., IL, USA). There was no statistically significant difference between the antibiotic medication methods and the wound infection incidence after the operation among the experimental groups. As examining the relations between the mandibular third molar operation methods and the wound infection incidence after the operation, there existed a statistically meaningful difference in the infection incidence according to the operation methods(p=0.020). And there was no statistically significant difference in the wound infection incidence according to the impacted depth of the mandibular third molar. Therefore, it is thought that there exists little necessity of prophylatic antibiotics medication when extracting the mandibular third molar of young and healthy men without any systemic disease in general; however, in case when it is expected that the possibility of infection will be high or the wound on the tissue will be severe, it is sure that the prophylactic antibiotics medication will be necessary.

Sagittal split ramus osteotomy (SSRO) is one of the surgical techniques used to correct mandibular deformities. In order to prevent many surgical anatomical problems, we observed the anatomical structures related to SSRO. In dry mandibles of Koreans, lingular tips were located somewhat posteriorly and superiorly on the mandibular ramus. On the coronal sections of mandible, the mean cortical width of facial cortex was increased toward the ramus region while the lingual cortex was thinnest in the ramus region. On the same sections, all the fusion points of the buccal and lingual cortical plate were located above the mandibular lingula and beneath the mandibular notch. So, performing the SSRO on Koreans, medial horizontal osteotomy should be done through the superior aspect of the mandibular lingula. The cut line is extended 5-8 mm posterior to the mandibular lingula to preserve sufficient cortical width to strengthen the involved osseous segments and reduce possible surgical complications.
