Because of the. rise in the incidence of high speed automobile accident and various gun shot wound, complicated vascular injuries are becoming more frequent. Inferior vena caval injury seems to be also in high incidence, but reports in the literature were rare. because of potentially lethal. Recently we have experienced a case of inferior vena caval injury due to stab wound on the posterior aspect of the right abdomen. This was successfully treated with inferior caval ligation on the both, proximal and distal of the injured infrarenal vena cava.

Although inferior alveolar nerve block is one of the most common procedures performed at dental clinics, complications or adverse effects can still occur. On rare occasions, ocular disturbances, such as diplopia, blurred vision, amaurosis, mydriasis, abnormal pupillary light reflex, retrobulbar pain, miosis, and enophthalmos, have also been reported after maxillary and mandibular anesthesia. Generally, these symptoms are temporary but they can be rather distressing to both patients and dental practitioners. Herein, we describe a case of diplopia caused by routine inferior alveolar nerve anesthesia, its related physiology, and management.

Purpose: The purpose of this study was to evaluate possible differences in the location of the inferior alveolar canal in male and female Egyptians. Materials and Methods: This cross-sectional retrospective study involved the evaluation of 210 CBCT scans of Egyptian individuals (18-70 years old). The inferior alveolar canal was localized by measuring 8 linear dimensions: 2 for the vertical localization of the mental foramen (superior and inferior to the mental foramen), 4 at the first molar bifurcation for the vertical and horizontal localization of the inferior alveolar canal (superior, inferior, buccal, and lingual to the inferior alveolar canal), and 2 for the horizontal localization of the mandibular foramen (anterior and posterior to the mandibular foramen). The measurements were statistically analyzed via comparative analysis, stepwise logistic regression, and receiver operating characteristic (ROC) curve analysis. Results: Six of the 8 measured distances differed to a statistically significant extent between the sexes. Regression analysis suggested a logistic function with a concordance index of 84%. The diagnostic accuracy capabilities of the linear measurements as sex predictors were calculated using ROC analysis, and the 6 best predictors for sex determination were selected and ranked from highest to lowest predictive power. Moreover, combining these 6 predictors increased the predictive power to 84%. Conclusion: The location of the inferior alveolar canal in the Egyptian population varies significantly by sex; accordingly, this anatomic landmark could be used as a reliable indicator of sexual dimorphism.

Objectives: To measure tympanic bone thickness (anterior-superior, anterior-inferior, and inferior wall), external ear canal length, and tympanomandibular distance that can be useful in cases that undergo tympanic bone resection. Materials and Methods: The temporal computed tomography (CT) images of 349 patients were retrospectively evaluated. The anterior-inferior, anterior-superior, and inferior wall thicknesses; tympanomandibular distance; and external auditory canal (EAC) bone canal length were measured from the narrowest part of the canal. The shapes of the EAC in the coronal and sagittal planes were also examined. Results: The numbers of female and male patients were similar, and the mean age was 49.45±13.95 years. The anterior-superior, anterior-inferior, and inferior wall thicknesses were 1.92±0.60, 2.54±0.74, and 9.16±2.20 mm, respectively. The anterior-superior and anterior-inferior wall thicknesses and canal lengths were greater on the right side (P<0.001). All measurement values were higher in males, except right tympanomandibular distance (P<0.05). A non-significant negative correlation was found between the age of the participants and the left anterior-inferior wall and tympanomandibular distance on both sides. Intra-observer agreement was high for all measurements. We observed four main shapes in the external ear canal in the coronal plane: Type 3, Type 2, Type 1, and Type 4 in order of frequency on the right, and Type 2, Type 3, Type 1, and Type 4 on the left. In the sagittal plane, we detected three shapes: oval (74.4%), triangular (16.3%), and round (9.4%). Conclusion: The anterior wall thicknesses and tympanomandibular distance should be measured on preoperative temporal bone CT to safely perform tympanic bone anterior resection, which is required in some otological procedures, and also to prevent temporomandibular joint damage.

We operated three cases of intrahepatic inferior vena caval obstruction from January, 1969 to February, 1978 at the department of Thoracic and Cardiovascular Surgery in Seoul National University Hospital. They were all female. And their ages were 33, 38 and 32 respectively. The lesions were the same site; just above the opening of the hepatic vein of inferior vena cava. In first case, segmental narrowing of the inferior vena cava without thrombosis was noted. In second case; thrombus occluded the inferior vena cava and left hepatic vein. In third case, we observed membrane of 4mm thickness which occluded the lumen completely. They were totally operated by using cardiopulmonary bypass. Their post-operative courses were good in the last two cases and re-obstruction was suspected in the first case.

A 21 year-old male patient had a diagnosis of Budd-Chiari syndrome caused by inferior vena caval obstruction. Conservative medical therapy failed to control the symptoms of both portal hypertension and inferior vena caval stasis. Portocaval or mesocaval shunts may relive the symptoms of chronic forms of Budd-Chiari syndrome. But when inferior vena caval stenosis is severe, another procedure has to be used. Cavoatrial or portoatrial shunt has been suggested. Therefore, a long Dacron graft was placed from the inferior vena cava just below the left renal vein to the right atrium. He exhibited almost complete relief of symptoms for 1.5 year postoperatively. And there was angiographic proof of patency of the graft. This simple procedure should be encouraged in treatment of these patients.

Nonrecurrence of the inferior laryngeal nerve always results from a vascular anomaly during embryonic development of the aortic arches. The nonrecurrent inferior laryngeal nerve is important clinically for two reasons, it is vulnerable during thyroid surgery and it is associated with difficulty in swallowing. It can be suspected preoperatively from signs associated with the vascular anomaly : dysphagea, thoracic x-ray images showing evidence of retroesophageal subclavian artery, or situs inversus viscerum. If such signs are noted, a barium swallow test and chest computed tomography are justified. We experienced a case of Rt. nonrecurrent inferior laryngeal nerve, which is diagnosed thyroid papillary carcinoma.

Purpose : The purpose of this study was 1) to find nerve damage after inferior alveolar nerve transposition and 2) to examine whether the soft tissue or bone changes around the nerve produce the compression to the nerve in the healing period. Materials and Method : Inferior alveolar nerve was exposed through the bony window and the scratch was made in the bone to be thought as the inferior alveolar canal. Suture was made after the nerve was repositioned. The nerve and surrounding tissues were examined with the light microscope and the fluorescent microscope before surgery and at 1 month, 3 months, and 5 months after surgery. Results : After surgery, the epineurium was damaged and the nerve was divided to several fascicles covered with the perineurium The newly formed fibrous connective tissue and vessels were seen around fascicles. There was new bone formation. However the nerve was not compressed by the connective tissue or the new bone. Conclusion : The results of this study suggest that neurosensory disturbances after inferior alveolar nerve transposition are resulted by the direct trauma in surgery rather than the compression to the nerve by the scar or new bone formation in the healing period.

Objective : This clinical research was conducted to test patients with dark circles by external application with Chinensis galla, Lithospermi radix and Salviae miltiorrhizae radix in cosmetics. Methods : We gave prototype cosmetics to 27 patients who volunteered for this clinical research in Kyungwon university from October 14th, 2009 to November 11th. Left inferior palpebra area of patients was treated with Chinensis galla, Lithospermi radix and Salviae miltiorrhizae radix in cosmetics(Experimental group) and right inferior palpebra area of patients was treated with placebo(Control group) for 4weeks. We observed change of darkness of inferior palpebra and subjective satisfaction. Also taking digital image and color meter were used to evaluate the effects of Chinensis galla, Lithospermi radix and Salviae miltiorrhizae radix in cosmetics. Results : Overall evaluation was slightly positive. It is more effective on Right inferior palpebra than on Left inferior palpebra to improve darkness of inferior palpabra in this clinical research. Conclusion : We can guess that cosmetics with Chinensis galla, Lithospermi radix and Salviae miltiorrhizae radix has some therapeutical effects in reducing the symptoms of dark circles.

하장간막동맥은 산후출혈의 매우 드문 출혈 혈관이다. 저자들은 질분만 후 하장간막동맥에서 출혈이 있었던 일차성 산후출혈 두 개의 증례를 보고한다. 두 환자 모두 저혈량성 쇼크의 징후를 보이고 있었고, 파종성혈관내응고가 의심되는 상태였다. 산후출혈의 흔한 출혈 혈관인 자궁동맥을 색전한 후에도 출혈은 지속되었다. 하장간막동맥 혈관조영술에서 상직장동맥으로부터 조영제의 혈관외누출이 확인되어 N-butyl cyanoacrylate를 이용한 선택적 색전술을 시행하였다. 이 증례를 통해 산도 손상에 의한 산후출혈이 조절되지 않고 지속될 때 하장간막동맥이 출혈 동맥일 수 있다는 점을 강조하고자 한다.
