Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

Macrostomia is a relatively rare malformation. There have been many surgical methods for the correction of macrostomia. The old method, a simple straight line closure , did not include reconstruction of the orbicularis oris muscle. Postoperatively, a depressed scar and severe contraction on the cheek were found, especially with animation. As a result, many authors have known that reconstruction of the orbicularis oris muscle was very important to avoid a depressed scar for the correction of macrostomia. The tendency toward lateral displacement of the reconstructed commissure has been attributed to linear scar contraction, and Z-plasty is advocated to prevent this deformity. However, we found that the Z-plasty scar may be conspicuous when the patient smiles. So we performed reconstruction of the orbicularis oris muscle to avoid a depressed scar, and straight line closure to avoid a conspicuous scar. In order to prevent linear scar contracture due to straight line closure, we overcorrected the new commissure. We treated 6 cases of macrostomia form May 1, 1996 to April 30, 1999 using straight line closure and reconstruction of the orbicularis oris muscle. Periods of follow-up were from 12 months to 35 months, with an average of 20,2 months. Every patient was analyzed clinically by ordinary scale method and anthropometrically by the ratio of abnormal distances to normal distances between cheilion and crista philtri. In 3 clinical assessments : symmetry of the commissure was excellent: degree of the scar at rest was good: and degree of depression with animation was excellent. The anthropometrical ratio was 1:1.05. Despite the fact that the linear scars were perpendicular to the minimal skin tension lines, the scars were inconspicuous. The muscle repair provided reconstruction to the modiolus and gave a natural appearance to the commissure, however it did not seem to provide sufficient bulkiness around the commissure. The straight line skin closure and repair of the orbicularis oris muscle provide effective functional and aesthetic reconstruction.

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.

In order to investigate the factors influencing QOL and life satisfaction of the physically disabled, the author interviewed, by using structuralized questionnaire, 440 individuals among the physically disabled who were participated in Health Examination from April to July, 1997. The questionnaire consisted of the general characteristics(sex, age, marital status, family number, etc), the Reintegration to Normal Living Index(RNLI) to assess QOL, and the single item of five-likert scale to evaluate life satisfaction. The means of RNLI were 16.2+/-4.8 in total score, 12.2+/-3.4 in daily functioning and 4.0+/-2.1 in perception of self. The respondents were less reintegrated toward social activities and relationships than impairments or disabilities. While the satisfied group was 47.3%, the dissatisfied group was 52.7%. As the results of multiple regression and logistic regression analysis, the significant predictors of QOL were age, education, job, grade of disability and subjective health status. The life satisfaction were related to economic status, job and subjective health status. To improve QOL and life satisfaction of the physically disabled, it is important that we improve their basic socioeconomic status by getting a job through rehabilitation education and induce them to have positive self-assessment by extending the opportunity of social participation.

We report a case of esthesioneuroblastoma with intracranial extension treated with surgical resection and chemotherapy. A 5-year-old child presented with visual disturbance, and was subsequently found to have a huge sized mass in the anterior skull base, suprasellar region and lateral ventricle. A bifrontal craniotomy with excision of the tumor through subfrontal and interhemispheric approach was performed. The patient received postoperative chemotherapy according to Tandem protocol. A follow-up magnetic resonance(MR) image showed that the tumor showed partial regression, however, there was no change in tumor size in lateral ventricle. Second operation with excision of remnant mass through a transcallosal approach was performed. MR image, 9 months after first operation showed the postoperative change in frontal area without enhancing mass. By employing staged operation and chemotherapy, the authors obtained good results in the treatment of esthesioneuroblastoma with intracranial extension.

The application of stereotactic techniques and endoscopy dates back to the beginning of this century and is almost as old as neurosurgery itself. However, endoscopic techniques progressed slowly for several reasons. A reappraisal of endoscopic techniques become popular about 1985. The major indication of endoscope in neurosurgical field is intraventricular procedures. Recently it can be used selectively in the intraaxial mass lesion associated cavity. For example, cystic mass, with liquefied necrosis, blood clot can be approached with endoscope. Authors present its intraaxial application in basal ganglionic hematoma in three patients. Conventional stereotactic guidance of neuroendoscope was done and the hematoma was gently removed through continuous irrigation and suction under video-guidance. The clinical course was uneventful. Brief overview is given of this intraaxial neuroendoscopic procedure.

Fluorescein fundus angiography is a valuable method in diagnosis and treatment of central serous chorioretinopathy. We observed 136 eyes of central serous corioretinopathy by fluorescein fundus angiography, between March, 1973 and September, 1974. Leakings are analysed by pictures and the following results were obtained. 1. The cases were classified by leaking patterns as following: Type I, leaking is unremarkable, Type II, leaking point appears at early arterial phase and fades out gradually. Type III. leaking point appears at early arterial phase and increases in density gradually, but the size of the leaking area is not enlarged. Type IVa, leaking point appears at early arterial phase and increases concentrically in the density and size. Type IVb. leaking point appears at early arterial phase and increases vertically (mushroom shape) in its size and density. 2. In large serous detachment of the macula, the leaking tend to be single and located at peripheral area. 3. In type IVa and IVb, the leaking tend to be located superiorly and nasally in midperiphery. 4. Photocoagulation can be applied more easily in type IVa and IVb for the location of the leaking points.

The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.
