Mandibular condylar fracture is common in mandibular fractures. Unlike other facial, skeletal fractures, most of mandibular condylar neck or head fractures are treated with closed reduction and subsequent functional therapy is essential for preventing complications including ankylosis, arthrosis and growth disturbance. From January, 2000 to September, 2002, we have treated 15 cases of mandibular condylar fractures with closed reduction by using functional appliance with bite block. Among these cases, we report a case of 14-year-old female with mandibular condylar neck fracture, resulted in good clinical and radiographic progress.

BACKGROUND: Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. MATERIALS AND METHODS: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. RESULTS: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. CONCLUSION: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.

Intracranial lipoma usually occurs at or near the midline, predominantly in the callosal cistern and very rarely in the sylvian fissure. We report a case of lipoma of the sylvian fissure without association with other congenital anomaly or vascular abnormality.

We present two cases of compression of the common hepatic duct by overriding of the right hepatic artery. One case is gall bladder, common hepatic duct stone and one case is right intrahepatic duct stone. We observed the compression of the common hepatic duct caused by overriding of the right hepatic artery in the both cases. The final diagnosis was made at operative fields. These patient were successfully treated by dissection of adhesion, suture, fixation between gall bladder bed and right hepatic artery.

OBJECTIVE: The aim was to evaluate whether the differences of PG concentration in follicular and peritoneal fluid during preovulatory phase exist between the women with and without endometriosis. MATERIAL AND METHODS: Twenty-three patients with endometriosis, 8 were stage I-II and 15 were stage III-IV, and another 23 patients without endometriosis were undergone laparotomy during late follicular phase. Peritoneal fluid from 46 patients and follicular fluid from 42 patients were obtained, and these samples were analyzed double times for PGF2alpha, PGE2 and estradiol. RESULTS: The mean level of PGF2alphain the peritoneal fluid was significantly higher in the group with endometriosis than in the control(P=0.0293), especially more significant in stage I-II endometriosis. Although there was no significant difference of PGF2alphaconcentration in the follicular fluid between the groups, the stage III-IV endometriosis group showed slightly higher PGF2alphalevel than both the stage I-II group and the control(P=0.0604). And also, there was significant positive correlation with the level of PGF2alphaand estradiol in the follicular fluid only in the endometriosis group(r=0.4988, P=0.0154), not in the control. However, there was no difference in the level of PGE2 and estradiol in the peritoneal or follicular fluid between the groups. CONCLUSION: Some alterations of PGF2alphalevel exist in the women with endometriosis. These are significantly higher PGF2alphalevel in peritoneal fluid with mild endometriosis and slightly higher PGF2alphalevels in follicular fluid with extensive endometriosis during preovulatory phase, which suggest that PGF2alphamay play some roles in subfertility associated with endometriosis.

PURPOSE: To determine the MR and CT imaging findings of inflammatory pseudotumor of the extraorbital head and neck. MATERIALS AND METHODS: We reviewed the MR (n=10) and CT (n=9) imaging studies of 11 patients with this condition (M:F=5:6, age range: 35-75 years), analysing each case in terms of location, occupying space, signal intensity, intracranial involvement, degree of contrast enhancement and adjacent bone change. Follow-up images were obtained in nine cases, and the response of each patient to steroid treatment was reviewed. RESULTS: Lesions involved the masticator space (n=8), the buccal space (n=6), the nasopharynx (n=5), the paranasal sinus (n=4), the parapharyngeal space (n=3), the prevertebral space (n=2), the orbit (n=2), the carotid space (n=2), the paravertebral space (n=1), parotid space (n=1), and the oral cavity (n=1). In ten of eleven cases, there was adjacent bone change. In three cases, the cavernous sinus was involved, and in two, the dura. One case involved both of them. At T2-weighted imaging, the lesions showed hypointensity in nine of ten cases; in four of nine, signal intensity was markedly low, and in no case was it diffusely high. In five of nine cases, the mass decreased in size after steroid therapy. CONCLUSION: Inflammatory pseudotumor showed iso-to hypointensity at T2-weighted imaging. Lymphadenopathy was not apparent.

PURPOSE: The aim of this study is to correlate the non-characteristic dual-phase CT imaging findings of hepato-cellular carcinoma with the observed characteristics of surgical specimens. MATERIALS AND METHODS: We studied four cases in which homogeneous low attenuation was observed during the arterial and delayed phases of dynamic CT scanning and in which hepatocellular carcinoma with coagulation necrosis above 95% was pathologically confirmed. We compared the findings of dual phase CT scanning, ultrasonography, angiography and Lipiodol CT scanning with the observed features of surgical specimens. RESULTS: Nodules were 30-50 (mean, 41) mm in size, and were round in three cases and oval in one. In all four cases, a low density lesion was observed during the arterial and delayed phases of dual-phase CT scanning. Ultrasonography demonstrated internal echo and the presence of a hypoechoic halo, implying that in all cases a capsule was present. At angiography and LiCT, minimal peripheral and central tumor staining or lipiodol up-take was observed. In all surgical specimens a complete capsule was visible, and histologic structures were mainly of the trabecular type, Edmondson grade II or III was recorded, and the mass had undergone extensive coagulation necrosis (above 95%). CONCLUSION: In cirrhotic liver which is hepatitis B-antigen positive, clear sonographic findings of internal echo and a capsule, rather than a simple cyst, indicate the possibility of hepatocellular carcinoma with extensive coagulation necrosis. This is so even if the arterial and delayed phases of dual-phase CT scanning indicate the presence of a low-density lesion, and in such cases additional work-up is therefore required.
